Answer to Question #32358 in Chemistry for dora

Question

can you give me a small informative background just a vision on how chemist gets the correct combination in creating a chemical. for example, i wanted to make a glue, how can a chemist calculate on how many oz needed in each chemical? does it needed a calcu or like calculating percentage? just a rerun i dont need a full teaching cause it will take years to learn, i needed for my thesis if the panel ask me on how does a chemist calculating. do they use percentage or how do they calculate the oz needed on each chemical.

Answer 1

Chemical equations are used to graphically illustrate chemical reactions. They consist of chemical or structural formulas of the reactants on the left and those of the products on the right. In a chemical reaction, the reactants are taken in an equivalent amount. There are several reactions which must take excess, for example about 1.5 equivalents. For the right balance in the reactions necessary to calculate the amount of the substance of each component by the formula n = m / M. There is such a reaction where is necessary to know the ratio of volumes of reagents. The chemical formula for white glue is (C₄H₆O₂)_n. The scientific name for white glue is polyvinyl acetate. The polyvinyl acetate is dissolved in water, in the ratio 1:1, to create glue.
