You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

Rates of reaction coursework introduction



Essays on strengths and weaknesses as a writer

writing mba dissertation - The rate of reaction is the speed of a reaction. When the solution is made more concentrated, there are a greater number of molecules in the same space. This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction. Introduction You know that some reactions happen very quickly (for example, potassium reacting with water). On the other hand, some reactions are very slow (for example, the rusting of iron or the setting of concrete). Many chemists in industry spend their careers trying to speed up or slow down chemical reactions. So this is a reaction of nitrous oxide turning into N2 and O2. Nitrous oxide is used in many, many applications, not just laughing gas. If we go with what we just wrote down. OK, so let's take this example, I'm going to write it down here. 2 N20 goes to 2 N2 plus O2. OK.
