Role of Catalyst in Chemistry

Role of Catalyst in ChemistryCatalyst is the element that reacts with the carbon atom of the element. Catalyst will be an essential ingredient in any chemical reaction and if it is present in a certain percentage in the chemical formula then it will convert the chemicals and the elements present in the reaction to simpler ones. Catalyst can also be called as the primary agent that aids in the conversion of various elements to simpler ones.This catalytic process can be in any aspect of chemistry as it can cause transformation of different elements to simpler ones and the reactions of this catalytic process will occur very easily. The reaction of the catalyst in the chemistry will not take place instantaneously but can take place on a certain time span depending upon the mass of the catalyst and the mass of the other chemicals that are present in the reaction.When the catalyst is used in a chemical reaction then there will be no need to remove the catalyst from the reaction because the catalytic process will take place without any issues. There are few materials like Fe, Co, Mn, Ni, Si, Cu, Ag, Cd, Cr, K, Fe, Mn, and Al in the periodic table that are catalysts and the process will start with the presence of these compounds. If you are a student and wish to take the examination in chemical reaction then you should have to give a special attention towards this topic.As the catalyst is used in the chemical reaction then it will undergo some changes and those changes will be the catalytic process. There are certain materials that are required for a proper catalytic process and these include the nickel, the iron, the cobalt, the cadmium, the mercury, the iodine, the sulfur, the chromium, the titanium, the titanium oxide, and the copper. If the catalyst is used in a certain quantity in the chemical formula then it will allow the reactions to occur and all these are the metals that are used in the catalyst.All these metals are termed as catalytic material and they have the capability of taking part in the catalytic process and this will result in the occurrence of the chemical reaction. It is the role of the catalyst to convert the elements into simpler ones and the material is active only when it will enter the chemical equation.The use of the catalyst in the chemical reaction will increase the speed of the reaction and this speed can be increased by the fact that it allows the reaction to occur and complete itself in a better manner. When the catalyst is used in the chemical reaction then it will enable the reaction to occur with better efficiency. The fact that the catalyst is used in the chemical reaction will facilitate the conversion of chemical elements into simpler ones and also the reaction will take place in a faster way.The catalyst is a definite and necessary component in the reaction and it should be taken into consideration when you want to perform the chemical reactions. The catalyst can be divided into two different groups and the first group includes the electrochemical substances and the second group include the semi-conductor. Each group has its own significance and role in the chemical reactions.

Staying Motivated - Private Tutoring

Staying Motivated BobbiM Mar 31, 2014 Getting motivated is one thing; staying motivated is another. Which one is harder for you? In order to stay motivated you should give yourself checkpoints on the way to reaching your goals. These checkpoints might include: -Monitoring your motivation for learning just as you monitor your comprehension when you read. Each time you sit down to study, ask yourself about the level of motivation for what you are doing. You have an internal body clock, which means that you will find that certain times of the day are more conducive to learning than others. Try to plan your study sessions around those times. -Studying the subjects you find the most difficult, or are least motivated to learn, first. Then move to the subjects that are easier, or those that you enjoy more. In that way you will be more likely to stay motivated to study the subjects you find the most interesting. -Planning some breaks in your study time-dont try to study for more than one hour without a short break because you will find it difficult to maintain your motivation. But what if you find yourself losing motivation? Its important to have strategies to follow in this scenario as well. It might help if you: -Take a break and come back to what you were doing at a later time. -Switch topics every hour or so. -Work with a study group. Misery loves company and others can often demotivated you. -Plan to study in the library or another quiet place if you find that your social life is interfering with studying because your friends are calling you or dropping by. Find somewhere to study where you will be free from distractions and temptation. Excerpt from  College Success Strategies  by Sherrie L. Nist and Jodi Patrick Holschuh.

Skype English TV Comparatives and Superlatives

Skype English TV Comparatives and Superlatives Hello! This is our first video recording of our Skype English Classes. In this video you will see Frank using comparatives in English. He is comparing his daughter to his son. Watch the video below, then read the notes to learn more about comparatives and superlatives in English. In English we use comparatives by adding an ER at the end of an adjective or adding the word MORE in front of the adjective. How do you know when to add ER or when to use MORE? Easy, for short adjectives (fat, thin, tall, rich, smart) we add ER. For long adjectives (intelligent, extroverted, beautiful, stupid) we put MORE in front of the adjective.We use than as our connecting word.Some common comparative mistakes:using BOTH more and er: Frank says, “My daughter is more taller than my son.” Incorrect. Correct, “My daughter is taller than my son.”using that instead of than. “My daughter is 3 years older that my son.” Incorrect. Correct, “My daughter is 3 years older than my son.using THE with co mparatives. Frank says, “The Peru is better than Chile.” Incorrect. Peru is better than Chile. We don’t use The with formal nouns unless it is part of the name: The United States, The Dominican Republic, The European Union.using the superlative rather than the comparative, “Peru has the best food than Chile.” Incorrect. “Peru has better food than Chile. Remember we use the comparaitives with ER or MORE when we are comparing 2 things, people, or places. We use the superlative when we are comparing 3-999,999,999,999 things, people, or places.If you have any more questions or would like to take a class on comparatives and superlatives please contact us.

Three Key Ways to optimise how the Brain Learns

Three Key Ways to optimise how the Brain Learns Guest post by David Morgan. Children spend so much of their life in a classroom. The average person spends fourteen thousand, one hundred and forty-five hours of life at school! But there are a few key ways that help the brain learn more easily and make that time better spent: 1. Prioritizing play Learning is optimized for children and many adults in an active, play-based learning environment. I think we would all agree that boredom is the death of learning! When schoolchildren are actively engaged in completing a learning task, it is more likely that the knowledge acquired will be retained by the brain. Numerous pedagogical studies have proven this principle over the years; trawl through your search engine to find many pages of relevant results! Children that are primarily kinaesthetic learners should have an extra emphasis on this kind of active learning, though all learning styles can benefit from it. 2. Shrinking Stress If boredom is the death of learning, then stress is the enemy of education. Neurologically, stress elevates your levels of cortisol and adrenaline which in turn reduces peripheral brain activity. You may have heard of this effect before: when the brain interprets there being a threat or risk of some kind, it shuts down all higher functioning and addresses the stressful situation at hand through the classic fight, flight or freeze response. All kinds of knowledge acquisition involve higher brain functioning, so any activities which create anxiety in the classroom environment will actually prevent learning. If a child is overly anxious, then it is important to focus on increasing his or her confidence through short learning exercises where failure is an unlikely outcome. 3. Mobilizing Emotion Emotion is one of the most prominent players in memory creation. In fact, selecting which memories to retain is one of the crucial roles of our emotions. As you might expect, when your emotions are disengaged, memory retention is much reduced. In an interesting paradox, the standard Victorian method of creating an atmosphere of fear or punishment in the classroom would have reduced the ability of the students to perform due to stress, but counteracting that, it might have helped them remember some knowledge taught. As a rule, however, scare tactics in the classroom are unadvisable! Positively enforced emotions lead to optimum performance AND good memory retention.

How to Enjoy a Car Trip with your Kids.

How to Enjoy a Car Trip with your Kids. Are you going on a car trip with your kids? Your friends make you worry a little bit asking only one question Are you crazy?. But you have such wonderful memories of past car trips when you were a kid. So, now you  want to take your  kids on the best car trip ever, but how? Dont worry! Ill give you a few tips how to have everything under control and enjoy the ride. My number one suggestion is to never let your kids be starving. Pack up nuts, fruits, crackers, cheese, beef jerky or whatever they like. Also bring a plenty of  water and soda. Do not ever travel without a big pack of baby wipes! It can come in handy when you clean your kids sticky fingers after eating snacks. And, of course, do not forget about sun cream, bug spray and also  the  first aid kit. You might think you dont need these, but bring them just in case. Then you may think about your kids travel entertainment. For instance,   everyone knows the alphabet game or car bingo. In order to make bingo more interesting let your kids make the bingo board by themselves. Let them write the words down they want in there. Older kids can write a travel diary. These diaries dont have to be expensive; a simple notebook would do just fine. Engage them to write down places you go and impressions they have. In a couple of years they will read this diary with a smile on their faces. Create a music playlist that holds the favorite songs of  the entire family. And sing them together like in a real rock band. Another fun thing to do is to give your kids a road map. It is a great time to teach them map skills which  is  an essential outdoor skill. You will be  surprised if this is the reason your son becomes an geography tutor. Or let them just read the funny city names like Bee Cave, TX or Angels Camp, CA. Car trips can be an exciting time  to your entire family and might even produce  some of the best memories of this fabulous summer 2015.

5 Top Online Resources for Practicing Languages to Fluency

5 Top Online Resources for Practicing Languages to Fluency 5 Top Online Resources for Practicing Languages to Fluency The internet has truly revolutionized language learning.I remember what it was like back in the day, when the Web was home to only a few amateur sites that claimed to teach various languages.I was at the mercy of  what my library chose to order or what the local bookstore happened to have in stock.Audio? Inconvenient.Video? Impossible.Actually speaking  with native speakers online? Unheard of!But today?Were able to practically take all these things for granted.So let us take a moment of silence to be grateful for the modern internet.With today’s veritable gold mine of target language media,  online courses  and other learning tools, there’s no reason not to excel at your chosen language.You can immerse yourself completely, so that you’re only interacting in your target language. It’s beautiful!But how exactly do you go about maximizing this wonderful modern world in which we live?Keep reading, because Im going to share the very best resources and tips with you! 5 Top Online Resources for Practicing Languages to FluencyOnline Conversation Sites for Speaking PracticeSpeaking is really what we think of when we consider fluency in a particular language. It’s communication! It’s impressive! It’s… intimidating?Sure. Whether you seek out speaking practice when you have only a few words under your belt (à la Benny Lewis from Fluent in 3 Months), or whether you decide to talk after a lengthy silent period, talking to a native speaker for the first time can be a scary prospect.That’s why conversation exchanges are one of the best ways to practice languages. You can find a partner on a site like italki. Someone who is in the throes of learning your native language from scratch. The mutual understanding works wonders and makes you both comfortable with baring it all in your stumbling first attempts at your respective target languages. The practice will make you all the more confident when you travel to the country or have to speak with a native speaker who doesn’t know about your language learning journey!And, on a side note, italki is the perfect platform for finding a paid language tutor if youre looking to invest a little more. A professional tutor can give you tons of feedback on your conversation skills.What to Do with Your Language ExchangeWhen you first seek out a language learning partner on any of the above sites (or all of themâ€"the more the merrier!), use the advanced search features so you have a higher chance of being able to relate to the personâ€"because you’ll actually need things to talk about. Consider gender, family status, age, hobbiesâ€"things you can find on their profile that might indicate you two have something in common to talk about. Believe meâ€"a conversation in which your only commonality is learning languages… well, it’s boring at best, and tedious at worst. Choose well, but rememberâ€"you can always call it off if things aren’t working out. Dont hesitate to try someone new!You’ll then meet up on Skype or Google Hangout. During the first couple sessions, I recommend simply getting to know one another. Talk about yourself, and ask them questions about themselves. Then, as you dive deeper, ask for constant corrections, as folks can be polite and overlook some errors. Constant corrections can be annoying, but your language skills will soar.After your sessions, SRS those corrections so you remember them until your dying day. Ask lots of questions, but remember that grammar points might not be the easiest things for your partner to discuss, so entrenched are they in their own native language. Ask for resource ideas like movies, books, comics and TV shows. Share jokes with each other to acquire a new sense of humor. With luck, you’ll build a real relationship and maybe make a new friend in the process!FluentU for Personalized Media-based Learning at Any LevelAre you not ready to dive into the conversational suggestions in this post? Or maybe you’d love to get into L 2 immersion, but you have some concerns, or the vast sea of the internet seems too big to find something you might like.FluentU can help you out.FluentU takes real-world videosâ€"like music videos, movie trailers, news and inspiring talksâ€"and turns them into personalized language learning lessons. It  teaches languages based on native media, but in bite-sized amounts, so you don’t have to sit through a whole movie or TV show you don’t grasp yet. You can absorb vocab and grammar from cartoons and hilarious commercials. It helps you wade into native media while holding your hand with interactive captions, quizzes to test your knowledge and other cool learning features when you need them. No need to shy away!With FluentU, you learn real languagesâ€"the same way that natives  speak them. FluentU has a wide variety of videos like movie trailers, funny commercials and web series, as you can see here:FluentU App Browse ScreenFluentU has interactive captions that let you tap on any wo rd to see an image, definition, audio and useful examples.

Swipe left or right to see  more examples for the word you’re learning.FluentU Has Quizzes for Every VideoWhat to Do with FluentULike with any language program, consistency is key: Devote 20 minutes a day to FluentU. Make ample use of the built-in SRS and word list features so you never forget new vocabulary. Fortunately, you dont even have to think too much about what to do because FluentU keeps track of all the words youve learned for you, automatically personalizing the whole experience.And when you need to take a break, check out the language specific blogs (Chinese, Spanish, French, German, English, Japanese, Russian, Arabic, Korean, Italian  and Portuguese, alongside this one) for lots of extra language learning information!Consistent use of FluentU will have you raring to go at more advanced language learning resources like conversation exchanges or targeted lessons with a tutor. And it’s a great option for accessing the world of native media.Chat Rooms (and Games) for Writing and Communication PracticeHa! You thought chat rooms didn’t exist anymore, didn’t you?Well, you’re dead wrong on that. Chat rooms may very well be a relic of the early 2000s, but they’re still alive and well in certain corners of the internet, albeit a little tougher to find. And you can find them in your target language!I personally love chat rooms because text chatting with strangers gives you real time language practice if you’re not quite ready to take on speaking just yet.How do you track down these ancient beasts? Search for forums (in your target language) about one of your interests, whether it’s gam es, gardening, politics, crafts, whatever. Many forums have a chat room! For example, heres a Pokémon chat room in French, a Spanish-language Star Wars/table top gaming chat  and a French math and science chat. Itll take some hunting, but you can get good results by translating chat room into your L2, and Googling that along with your hobby/interest of choice.If forums aren’t your style, many online multiplayer games have that same real-time text that we’re after. Think World of Warcraft or League of Legends. You jump right in, and players converse in real time. All you have to do is start up the game in your target language, and many of these games have tons of different language options. Games are also great because they can be more active and easier to find than forums.What to Do with Chat RoomsWhat do you do once you’ve found a chat room or game? I recommend eavesdropping at first. Watch others’ conversations. What are they saying? How are they saying it? Take note of n ew vocab and slang, and SRS those so you remember them later. Then, when you’re ready, try answering in short, easy phrases. Stick to things you knowâ€"don’t attempt to express complicated ideas if your vocabulary is limited to that of a first-year textbook. But be patient, and you’ll slowly improve.Considering these places are not learning sites, rest assured that mistakes may be met with laughter and teasing. Just dust yourself off when the inevitable embarrassment hits you. On the bright side, you’ll remember not to repeat those mistakes!Twitter for Additional Immersion and ExposureWe all know that changing default languages is a great way to immerse and practice a new language. If you’re studying a new language, you should already have changed the language of your phone, your email client, your Web browser, even your OS!So, why is Twitter any different?Twitter is unique in that when you change the default language, you’re not just seeing the options and onscreen word s translated. Instead, you’ll default to seeing tweets from target language sources! You’ll be constantly learning new online slang and abbreviationsâ€"lots of snippets of natural language.What to Do with TwitterHow do you go about changing your default? If your browser is in your L1 (or a different language), simply click on your little profile pic in the upper right corner of the page. Go to Settings, and then the language option is the first one down. And if you dont have an account and your browser is already in your target language, your Twitter will default to your target language when you sign up.Now what? Check those trending hashtags on the left-hand side of your home page! Most tweets  will probably be in your L2, so get in that reading practice. (If theyre not in your L2, its probably because you already follow English-language accounts, and the algorithm is trying to cater to youâ€"just change the location setting by clicking Change next to Trending and you should ge t better content.)You can also look for topics of interest in the search bar to find people talking about your favorite hobbies. The short format makes reading easier for those of us that shy away from novels or even blogs. It’s especially great for beginners who can probably parse a quick sentence, but maybe not long, convoluted paragraphs of a literary novel.And then, follow the Twitter users you enjoy reading. That way, your feed will be peppered with target language exposure. Even when you’re checking social media during work, you’ll have to come into contact with your L2!Online Tutors for Lessons and CorrectionsWhile not freeâ€"and I love free resourcesâ€"an online tutor can advance your language skills like nothing else in this mortal coil. You can get a real-life tutor by checking local universities or venturing online and hiring one from italki at very affordable prices per lesson.Another great source that specializes purely in online language tutors is Verbling, where you can  explore hundreds upon hundreds of language teachers and find the one whos just right for you.  But why would you do this after I’ve told you that you can get language practice for free with a language partner?It turns out, trained tutors are trained for a reason!A tutor with experience in teaching will be able to give you pinpointed language advice. They’ll have a vested interest in your skills and weaknesses, and how you cover up those weaknesses. You won’t have to worry about switching back to your native language as you would with a language exchange partnerâ€"it’s all you!A great tutor will keep you talking and force you out of your comfort zone so that you can expand and be comfortable in more situations. And it’s all tailored to you. If you need writing practice, a tutor will ruthlessly correct your writing. If you need to get through a class, tutors will help you through your particular curriculum. And if you just want targeted conversation practice, tutor s are there for you, too.What to Do with Your TutorWhen you find a tutor you think you might like, send questions before you meet. Really explain in detail what your issues are and what your goals are, and where you see yourself going. The more detail the better, as your tutor can decide how to help you out.In particular, grammar questions and issues are great to bring up with a tutor. A professional teacher is much better equipped to explain grammar and address your questions than a language partner (although language partners can be great in letting you know what “sounds right”).After your meetings, SRS corrections (like always!). Make sure you meet consistently, or decide on a particular number of lessons. Take lots of notes before, during and after so that you’re gleaning all you can from these sessions. And then, when you go out into the real world (or just to Skype to meet with your conversation partner), apply what you’ve learned! Constant application and practice are what stretch your abilities and keep you improving.Don’t underestimate the variety and depth of online language learning tools.There really is something out there for everyone, at every stage of learning.And before you know it, youll be moving effortlessly through online spacesâ€"all in your new language!
