How Chemistry Uses Radicals in Chemical Reactions

How Chemistry Uses Radicals in Chemical ReactionsIn chemistry, radicals are inorganic particles, some of which can modify the rest of the molecules of a given compound. They can either be attracted to or repelled by the molecules that surround them and they play an important role in the chemical reactions that occur within the body.The middle radical-type proteins are responsible for the changes in the overall physical properties of the molecule. For example, the outermost coating on our skin, called the epidermis, consists of four layers of keratin, or protein-rich cells, each linked by a fibrous protein called collagen. The middle radical molecules, however, do not attach to the keratin but instead use their attractive chemical energies to break apart the collagen, changing the outer layer into a lipid called 'sebum'.A radical molecule is composed of an electron (the negative type) attached to a negative or proton (the positive type). The molecular structure of a radical can be tho ught of as a chain with two-or three-substituted radical centers, which are exposed to the environment of a strong reaction. These bonds are unbalanced, so that their energy levels are out of balance, which will cause the formation of what we know as a radical. When this happens, it is called a 'catalyst.'In a catalytic effect, the reaction of a catalyst begins when a catalyst is added to a catalyst-based system, and the system's reaction speeds up by releasing more energy than needed to allow it to perform its job. Normally, the reaction starts with a carbon atom added to the catalyst. Once the catalyst is in contact with the catalyst-based system, the system's energy level and the energy of the new carbon bond that has been created by the two atoms is an optimal combination, allowing the reaction to occur. The process is then repeated with other carbon atoms, if necessary, until the catalyst is used up.When a catalyst begins a reaction, it creates a hole in the catalyst system, ca lled a 'plug'. At this point, the catalyst can no longer be used to complete the reaction. It is not uncommon for the resulting hole to be filled by another catalyst. This makes the process less efficient, however, and the holes build up in order to fill in the new holes left by the old ones.The radical mechanism in this case is different, however, and it produces a gap in the mechanism that allows a new hydrogen radical to be produced. With the new hydrogen radical comes another enzyme that can then be used to break down the original radical, allowing the immediate completion of the reaction. This is why there are radicals that 'give off' hydrogen radicals when they undergo a chemical reaction.Of course, there are also radicals that react with other radicals to create a new molecule of the compound, making a chemical reaction even more complex. There are two common methods of creating these new molecules: by random changes in the reactants, and by reactions that involve changing th e reactants to forms that already exist in the chemical medium. But the biggest mystery in all of chemistry is how to make the pathway for producing the new radical molecule so simple that any chemist can manipulate it.Science has done much research on the structure of the building blocks of life and has successfully learned how they are formed and how they are modified by the chemicals they need to be able to survive. The path that science has taken to answer the question of how chemistry uses radicals in chemical reactions is one that will continue to be studied and expanded upon, and that will determine whether or not life on earth can ever be discovered.

Entrance Exams - Does your child need a tutor

Entrance Exams - Does your child need a tutor In recent years there have been many debates regarding the standard of British schools. We are seen as a world leader in education by many countries abroad but at home teachers and parents sometimes disagree. By the time children reach the age of 9 many parents are frantically researching which top independent or grammar school their child could obtain a place at. Once they know which school they would like their child to attend the next task is to evaluate their child's current level at school taking into account their strengths and weaknesses. Most parents have a pretty good idea which subjects their child struggles and excels at but a teacher or private tutor can help identify exactly what kind of help is needed. The school's website often provide past exam papers and indicate what would be seen as a pass mark, this gives parents a good indication of the school's standard and if their child would be able to pass the entrance exam. Often the child is bright but lacks self confidence or the child excels in one subject but struggles in another. Other children have specific learning difficulties such as dyslexia and need a tutor that specialises in this area. Most school teachers will tell parents to encourage their children to practice, practice and practice, however unless a parent has the time and dedication to ensure the child does just that, more often than not the child is left alone to struggle leading to lack of motivation and self confidence. First Tutors see hundreds of parents asking for help to ensure their child performs best in entrance exams. Below are 3 top tips to consider when thinking of finding a tutor to help your child pass entrance exams. TIME Perhaps the most important factor is time. Don't rush into looking for a private tutor 3 months before your child is expected to sit the entrance exams. This will only add to the pressure your child is going through. A good year or more before the exam date should provide plenty of time for the tutor and your child to bond. WHICH TUTOR TO CHOOSE A good private tutor will work on your child's confidence and boost their potential by providing them with valuable studying techniques. If lessons are face to face and your child is confident using a computer ideally a tutor will back up lessons by providing extra resources or help via email, Skype etc. Here at First Tutors we have some very talented tutors! When searching for tutors via the website take your time to read their profiles but more importantly look for feedback left from previous First Tutor clients. Feel free to contact as many tutors as you wish to discuss all your tuition needs before deciding which tutor to go ahead with. QUESTIONS TO ASK YOUR TUTOR It's important to have an idea of how your tutor will work with your child. Some important questions to ask your tutor are: Who provides the learning materials? Do they set homework? How do they plan to make lessons engaging? How often will the tutor provide feedback to the parents regarding your child's progress? Can the tutor commit to long term tuition (eg. more than 3 months)? HOW YOU AS A PARENT CAN HELP YOUR CHILD. Ask the tutor how you can help reinforce your child's skills. Keep regular contact with your tutor so it makes it easier to communicate if any difficulties arise. After each lesson talk to your child to evaluate if they seem positive about their progress. It's easy to register with First Tutors and start searching for the best tutor for your child's needs.

It's also great for those who love to write but don't want to worry about how to get their ideas across in print.

Online Subtracting mixed Fractions Tutors

Online Subtracting mixed Fractions Tutors Mixed fractions are the numbers which are formed as a combination of a whole number and a proper fraction. A proper fraction is a fraction where the number in the denominator is greater than the number in the numerator. Subtracting mixed fractions involves converting a mixed fraction to an improper fraction (fraction where the number in the numerator is greater than the number in the denominator is an improper fraction). After calculating the answer, the improper fraction should be converted back into its mixed fraction form. Example 1: Subtract the mixed fractions, 6 2/3 41/3. First convert the given mixed fractions to improper fractions. This implies: 6 2/3 = [(3 * 6) + 2]/ 3 = 20/3. Similarly, 4 1/3 = [(3 * 4) + 1]/ 3 = 13/3. Subtract the above two improper fractions: 20/3 13/3 = (20 13)/ 3 = 7/3. Now converting 7/3 to mixed fraction, we do the long division which gives quotient as 2 and remainder as 1== 2 1/3. Therefore, 6 2/3 41/3 = 2 1/3. Example 2: Subtract the mixed fractions, 2 4/5 1 3/5. First convert the given mixed fractions to improper fractions. This implies: 2 4/5 = [(5 * 2) + 4]/ 5 = 14/5. Similarly, 1 3/5 = [(5 * 1) + 3]/ 5 = 8/5. Subtract the above two improper fractions: 14/5 8/5 = (14 8)/ 5 = 6/5. Now converting 6/5 to mixed fraction, we do the long division which gives quotient as 1 and remainder as 1== 1 1/5. Therefore, 2 4/5 1 3/5 = 1 1/5.

How to Set a Price for my Portuguese Lessons

How to Set a Price for my Portuguese Lessons What Fees Should You Charge for Giving Portuguese Lessons? ChaptersWhat Type of Courses Will You Teach?Location is Key in Setting Prices for Portuguese LessonsWhere do Portuguese Courses Fall?What it All Boils Down ToSpeaking more than one language is a valuable asset in more ways than one.Being bi- or multilingual boosts your cognitive ability, enables to you multitask better â€" or, conversely, enables better focus on the task at hand, and it provides a whole range of other mental and psychological benefits.But that’s not what this article is all about. Today, your Superprof wants to help you make the most of your most marketable skill â€" your ability to speak Portuguese by giving some tips on how to set a schedule of fees for the lessons you are so eager to give.Eager to give lessons, indeed! But not eager to give them away...Now we look at some factors that will influence how to set your prices just right so that your students feel they get the best value for their money.CAPLE or CELPE-Bras?Will you teach adults?Will you teach Convers ational Portuguese, for prospective holidaymakers?Will you teach Portuguese for Business?As you can see from the sheer variety of courses you may offer, either as a native speaker of Portuguese or one who has mastered Portuguese through language studies, there must be a difference in pricing, from course to course.You should not charge the same price for Business Portuguese lessons as you would charge a student preparing for a language exam.Furthermore, the duration of lessons would be different: a four-year-old would not have the same attention span as an adult, and adults learning Portuguese conversation may not wholly benefit from a full hour of language instruction like a student preparing for an exam would.One more consideration: how many students will you teach at one time?Some language teachers offer discounted rates to small groups â€" no more than 8 learners, while others offer discounts on their overall price for learners who pay for a block of language classes upfront.Let ’s paint the scenario of giving Business Portuguese classes.You have approached several international companies with the idea of providing language lessons to their staff, onsite.The HR or training manager really likes your idea and awards you a 10-week contract to teach select employees all about Brazil’s language and culture.They will provide a room for you to conduct your lessons in, equipped with all of the necessary accoutrements: overhead projector, computer, dry-erase board...All you need to bring are textbooks, worksheets, other resources and learning materials such as Powerpoint presentations and maybe some flashcards and other media.Naturally, you would not charge each company employee for those Portuguese lessons; instead, you would negotiate a fee with the training manager â€" hopefully, a reasonable one; overcharging would result in no deal.Now, for a different example...Let us suppose that your prospective clients’ son is marrying a lovely person from Portugal an d the wedding is to be held in Covilhã â€" not exactly a big town; not one where many English speakers would be found.Naturally, there must be conversation between the families and, most likely, there would be a bit of tourism involved.In this instance, you may recommend that your soon-to-be students purchase a textbook and Portuguese dictionary themselves and you would develop a curriculum based on their needs.Perhaps, so that they might communicate with their future in-laws, you would help them develop speaking and listening skills â€" teaching them words and phrases suitable to the occasion, and mostly foregoing reading and writing. How would you prepare for these Portuguese lessons?How much would you charge this family per hour of Portuguese instruction? That depends on one, very important factor.How much you may charge for Portuguese lessons depends on where you are located Source: Pixabay credit: Andras BartaLocation is Key in Setting Prices for Portuguese LessonsThere are th ree things that matter in property: location, location, location (incorrectly attributed to) Lord Harold Samuel.Not only is that phrase often incorrectly attributed to our most famous real estate magnate, but it is also inaccurate that location only applies to property.Where you give your lessons is an important determining factor in setting your prices for teaching Portuguese vocabulary and pronunciation. For one, if you live in or around London, you may find that pricing yourself competitively means charging far more per hour of instruction than, say, someone who teaches Portuguese in Birmingham or Leeds.Conversely, those who bring Brazilian culture to small towns such as Warminster or Swanley may find themselves overwhelmed with requests for lessons â€" and may charge slightly higher fees, simply because there is little to no competition   from other teachers in those regions.However, if you offer Portuguese lessons online, you may find yourself setting prices for each hour of in struction far lower than if you taught in person, no matter where in the country you are.Find out what qualifications you need to teach Portuguese online or in a classroom...There is vigorous and healthy competition among tutors for students learning Portuguese online!So, how can you give your students the best learning experience while still earning enough to make a decent living?1. Find out what local pricing for foreign language lessons is and set your prices accordingly.2. Offer extras: maybe you could hold free workshops or seminars at your local community centre or library in order to attract prospective students.3. Study the market and adapt: if indeed you do live in a small town where there is very little second language instruction going on, you can promote your skills as a teacher to bring about more opportunity â€" for yourself and for students.You may also teach Portuguese online. Where do Portuguese Courses Fall?In the spectrum of language learning, Portuguese is admitt edly far from the Number 1 choice for most anyone who wants to learn a new language.Most students desiring to learn a language generally prefer to learn German, learn Italian or learn French, with others preferring to speak Spanish or Arabic.There is even a substantial slice of the population who see more value in learning Mandarin Chinese than the Portuguese language!Fair warning: you may have an uphill battle convincing any learner to choose this Romance language over any others.A strong argument for the need to learn Portuguese comes from the British Council, who warn that the dire shortage of language instruction that besets our nation could cost us â€" both economically and culturally.You may use their plea in your marketing strategy! In proposing that people learn to speak Portuguese, either in a formal class or in a language course you establish and teach, you become an instrument for driving the benefits of foreign language skills in your community and for our country’s gr eater good.How much you earn from giving Portuguese lessons depends on many factors Source: Pixabay Credit: SatchappsWhat it All Boils Down ToHow much should you charge for teaching people how to speak Portuguese?That depends on where you will teach Portuguese speaking â€" the town/city as well as whether you teach in a classroom environment or in your home.Or in language learners’ home or through online lessons.It also depends on the level of language training you offer.Beginners would probably pay less than intermediate-level students who, in turn, might find the financial burden of learning a new language less than someone who conjugates irregular verbs in Portuguese just for the fun of it.Some language training companies in London charge as much as £45 per hour of face to face instruction, but they offer a discount if blocks of lessons are paid for in advance â€" say, 10 lessons for £400.One language school charges an extra £15 should someone wish to sit in on their friendâ €™s language study session.Those same companies charge less per hour (only £35) for the same lessons given via webcam simply because there is virtually no overhead incurred by online lessons â€" no classroom to pay for and no travel time or transportation costs to meet their students for lessons.And, our research shows that Portuguese for Business language classes cost significantly more than learning Portuguese conversation skills ( £75 per hour versus £35!)Superprof has 142 registered Portuguese tutors. Every one of them offers lessons online and most of them offer their first hour of lessons free!The average price of a Portuguese lesson on Superprof is £14 per hour, irrespective of whether the help needed is for test prep or Portuguese pronunciation.Now that you have a range of prices and factors to consider in setting your fees for language study, we leave you with a final tip:Don’t price yourself out of the market!It might be tempting to set your prices low in order to att ract more students â€" or high in order to generate enough revenue to subsist on, but beware: going to either extreme may send clients away!Mid-range is the best pricing; the rest of your earning potential will be met by your teaching methods and enthusiasm!Now follow this step by step guide to giving Portuguese lessons...
