The Essential Ingredient in Analytical Chemistry

The Essential Ingredient in Analytical ChemistryAn empirical formula is a mathematical formula that uses observed data to formulate a particular equation or formula. It is applied in all areas of science and has been proven to be effective in several ways.For example, to know what happens to a molecule under pressure, a chemist does not require knowing what happens in the periodic table of elements. A chemist needs only to know what happens under pressure. In many cases, the chemical bonds are unstable at these temperatures and this instability gives rise to the volatile aromatics that are present in volatile organic compounds (VOCs).An empirical formula can help in knowing how volatile aromatics (VOCs) react with compounds under different circumstances and this is useful to a chemist for he or she needs to know what reacts and which does not react under the same circumstances. These formulas are applicable for almost all chemical reactions where one element can interact with another to form molecules that are found in the most common substances like gasoline, oil, and so on. This type of formula can also be used to define reactions in other processes, such as the production of carbon dioxide, chlorinated gases, or water vapor.The equation is commonly known as 'Eqular' or 'Eqo' and is formulated in an analytical chemistry course. If one understands Eqular, he or she is well on his way to becoming an excellent analytical chemist who can predict exactly how an analyte will react under a given condition. Eqular can be used to calculate the reaction potential of a compound by reading its molecular weight, the reactivity constant (Kr), its ionic concentration, and its time to complete a reaction. It can also be used to determine the change in the functional group configuration during a reaction and that too under a particular reaction conditions.There are actually several versions of Eqular, the most popular of which is the 'Eqular-Bond Formula'. This is derived fro m the point that the bond is inscribed between two atoms of the same element. Thus, when the two atoms are added, they result in a reduction in the amount of their collective valence electrons.In addition to Eqular, there are other formulas that are used in analytical chemistry that derive from Eqular. They include the 'Synergy Formula' and the 'Imperfect Equilibrium Formula'. They are derived from Eqular. Also, two other formulas derived from Eqular are the 'Harpoon Formula' and the 'Turbulence Formula'.But the most important thing is that Eqular is essential for understanding how chemical reactions occur, as this formula has been proven to be very useful in many areas of science. It is therefore worth learning this formula so that one can have an insight into how chemistry works.

Introducing Yourself Online and in Person

Introducing Yourself Online and in Person First impressions have a lasting impact. It is critical therefore to be equipped with the know-how to create the right impression on people you meet online or in person for the first time. This article focuses on how to achieve this when introducing yourself to a room full of people or to a pen pal online. Step 1: Plan The first step of introducing yourself is to come up with a plan. List the main information you wish to share, such as your name, where you live, your school, your program, your goals, your job, and other interests. To create an informal tone, mention your hobbies and pastimes. You may want to emphasize what makes you different from your peers. Plan to end with a question. Questions help to continue the conversation and make you seem less self-centered. An example of an appropriate question after introducing yourself to a small group could be something like this: Now that I have told you a little about myself, could you tell me a little about yourself, too? Step 2: Understand your audience While planning your message, be aware of your audience’s interests. If they are students like you at a different college, they will be particularly interested in your school and program. Some will be interested in your career goals while others will want to delve into the details of your social life. Older readers might be interested in your family life. Readers in another country will want to know about your city and neighbourhood. If your audience is pressed for time, they won’t want to read or listen to a long treatise about your lifeso it is best to keep it short. Once you have understood your audience, you will get a sense of what to emphasize. Keep your tone friendly and informal to make you seem approachable. Avoid slang and aggressive language. You want to put your audience at ease. Step 2: Revise written introductions Write a draft, and then check it for embarrassing errorsespecially if you intend to post it online or send it in an email. Make sure to capitalize the first word of each sentence, your name and the pronoun “I.” NEVER USE ALL-CAPS. It makes you look like you are shouting. Remember to put a period (.) at the end of your sentences and a question mark (?) at the end of questions. Important! Use exclamation points (!) sparinglyyou don’t want to seem crazy. Finally, check your spelling and grammar with the VirtualWritingTutor.com grammar checker, and eliminate your errors before sending your message. Step 3: Practice oral introductions Practice your pronunciation for those occasions when you have to introduce record yourself or speak to a live audience. To make sure that you pronounce words correctly, enter your text into the VirtualWritingTutor.com and click on the speaker icon or download the MP3. Once you are sure of your pronunciation, practice reading your speech aloud to a classmate to determine the reaction of the audience in advance. Encourage him or her to ask questions and be honest about the weak parts of your introduction. Memorize your introduction. It will help you to create an impression of self-confidence. If you have to refer to your notes, read a sentence, look up, and say it. Step 5: Reduce your anxiety While delivering the speech to a room full of people, try to relax. Find a quiet place to breathe slowly and deeply. Instead of telling yourself that you are nervous, tell yourself that you are excited. Stand up straight to portray a sense of confidence and strength. Make eye contact with the people in different parts of the room. Use humor instead of apologizing for mistakes. It will indicate that you are comfortable and likable. Undoubtedly, you can introduce yourself in a speech or in a written message to create the right impression with just a little forethought and effort. The elements of proper planning,  simplicity, feedback from classmates, confidence, and humour will guide you through the process to a result you will be proud of.

Do you think children face peer pressure - ALOHA Mind Math

Do you think children face peer pressure Peer pressure is the feeling when child feels the need to adhere to a group of friends that they have. This peer pressure can influence how children dress, the things they want buy, what kind of music they listen to,  the places they want hand out at etc. These characteristic and behavioral patterns usually develop at a very early age, when children actually start to try and get the other kids to play games they want. Children face peer pressure at different stages of their lives as they grow to be teens and then adults. It is very important for a parent to identify this from its roots and always keep an eye on their kids because as they grow, parents need to be their support system and help them recognize and cope with their wants in terms of doing what they really want to do and to be able to say no to their peers whenever needed and still remain a part of the group. Peer pressure is a progressive stage as parent you cannot know the effects overnight, they need to more cautious and know their children well and see the signs as they are growing and nip it at the bud. If you children start hanging out and do similar activities with a group of peers you don’t think they in fit in with then that’s the first sign for a parent to start working with their kids. To tackle an issue as sensitive as peer pressure, parents will need to start spending more time with their kids, listen to them with more attention, Monitor their daily activities with a close eye and always keep a discussion open without being judgmental. This in turn will encourage your kids to share and discuss their problems with you making it an easier process for you as parent to help them out of peer pressure. All of us as children or adults have faced peer pressure at some point of our lives. Let use this forum and share our experiences to help other learn from it.

Emojis could soon be appearing on certificates - Tutor Hunt Blog

Emojis could soon be appearing on certificates Forget a* grades beaming emojis could soon be appearing on certificates Forget a* grades beaming emojis could soon be appearing on certificatesSchoolsA secondary school in Kent has been censured for using emojis to display pupils` GCSE scores. St John Fisher Catholic School in Chatham displayed the GCSE results of all year 11 pupils on a colour coded board, with emoji faces representing their grades. The decision to display the results in such a way was not a popular one: less than a week after the array of faces had been put up vociferous opposition from a number of parents led to their removal, and a more traditional - numerical - method being employed. Once would assume that the highest grade would be represented by a yellow face positively beaning with happiness; while the lowest grade would be indicated by as much sadness and grief a little graphical countenance can show. The headteacher explained that the emojis actually correlated with each pupil`s personal targets - so the pictograms are an indication of a positive or negative outcome; `Although the display board was not intended to cause any upset, we have taken the decision to remove it as three pupils in total have asked for their details to be taken down and a small number of parents have been in touch with us. ; The focus must be on improving students` life chances and we will continue to support each pupil and help them work towards their targets.` Emojis have become all the rage recently - only a few years ago it was impossible to send much more than a crudely constructed face, with deft arrangement of a bracket, a colon and perhaps a hyphen if you were really feeling artistic. Now mobile phone users can chose from hundreds of different faces, all clearly showing a variety of emotional states. The old maxim that a picture says a thousand words certainly feels true when you add an emoji to a concise text message. They do feel rather playful and sophomoric though - their inclusion would certainly not be appropriate in a business email, and it is unlikely that emojis will feature prominently in the next booker prize winning novel. Maybe this is the reason that there were complains when they were used to depict the GCSE grades at the John Fisher School. There are many academics who take the whole business of emoji`s very seriously though. Vyvyan Evans, former professor of linguistics at Bangor university, says their use is considerably altering the way in which we communicate. His latest book `The Emojo Code` opposes the view that their usage leads to lazy communication. `The naysayers, the doom-mongers, the self-appointed grammar police in the popular press and so on argue without any evidence that things like emoji are basically the equivalent of an adolescent grunt,` Professor Evans has said. His theories seem to imply that that human communication actually has more to do with posture and tone of voice - the pitch itself - rather than the purely linguistic content. Emojis are just another way that human embodiment is creeping into technological use. A trivial example of this is how the telephone replaced the letter (or telegram) as the primary method of long distance communication. We can learn more information about someone - how they are feeling, their attitudes and state of mind - through a brief telephone conversation, where we hear not just their words, but (critically) their tone of voice too, than we can from a lengthy letter or email. Whether smiling or frowning faces are a good way to convey how a student has performed in an exam is another matter of course. In my opinion a simple percentage is the best option, not just for clarity, but because it offers a such a high resolution of grading. A student who just scrapes a C grade will have performed considerably worse than a pupil who barely misses a B grade - though this detail will be masked by the final mark they both receive. At university of course things are even worse: a student who just manages to attain a 2:1 could be many marks behind another student who just misses out on a first. Displaying pupil`s results in order of their grade could help to motivate them - and it should be pointed out that the John Fisher School was displaying the pupils` progress in emoji`s - these weren`t final, or even predicted marks. Do Emoji`s have a happy future in the education sector - it seems doubtful to me, but only time will tell. 2 years ago0Add a Comment

4 Habits Students Need to Develop Before They Start College

4 Habits Students Need to Develop Before They Start College San Diego College Tutoring Tips: Develop These Four Habits Before Starting College High school students will have learned a number of study habits that helped them thrive in their classes for the last four years. They had the guidance of teachers and tutors to help them be successful and prepare to apply for college. Students have worked incredibly hard in order to gain admission to a great college, but now all the rules have changed, and they will start out with a blank slate once they arrive on campus. One of the most difficult things for students to do is adjust their study habits to whats appropriate at the college level. Students will have more freedom and control over their schedule, but this will also require greater responsibility our private San Diego college tutors are here to help you prepare for college. 1. College-level time management Managing time in college is very different than the heavily structured environment that high school students experience. For the most part, high school students are guided by their teacher each step of the way and given short-term due dates. For example, the rough draft of their paper is due next week, the final draft is due two weeks from now, and the outline is due tomorrow. In college, however, students are given a date three or four weeks from now when their entire paper needs to be completed. Students who are not used to managing their own time will often struggle to get things done on time and end up pulling an all-nighter which can be stressful and result in a lower quality assignment. 2. Maintaining a balance Most college freshmen have trouble maintaining a healthy work-life balance. They are not used to college-level assignments and have the most freedom theyve ever had in their life thus far. Many students find that they spend all of their time working and dont have any time to get to know new people or participate in campus activities. Other students may spend all of their time socializing and forget about work altogether. This can put students at risk of dropping out or being forced to repeat classes in future semesters. Its important to talk about how to maintain a healthy balance before arriving on campus so that students experience an easier transition (READ: Orange County SAT Tutor Tips: The Summer SAT). 3. Personal finance Once students enter college, they will become responsible for their own finances. This can be exciting and scary at the same time. A portion of college students will have learned how to manage money at some level by working at a job while they were in high school but others will be earning their own money for the very first time. College freshman will also be responsible for making sure that their savings last them through the end of the term and that they are able to borrow money responsibly, if necessary, to pay their tuition and fees. Its essential for students to learn the basics of personal finance before heading off to college on their own. 4. Broadening your horizons College is also an opportunity for students to get to know people from many different places, take classes about things theyve always been interested in, and get involved in the general college community. Many students want to stay within their own social circle, especially if they are attending their local college, and never move away from their comfort zone. Although it can be helpful to be around familiar things during the initial transition, college students are encouraged to broaden their horizons and learn about new subjects, cultures, and potential career options, so they have more doors open for their future.
