Define stoichiometry.
Answers
Answer:
the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers.
Answer:
Stoichiometry is exactly that. It is the quantitative relation between the number of moles (and therefore mass) of various products and reactants in a chemical reaction.
Chemical reactions must be balanced, or in other words, must have the same number of various atoms in the products as in the reactants.
If a chemical reaction is not balanced, no information about the relationship between products and reactants can be derived. So the first thing to do when you see a chemical reaction is to balance it. We balance reactions by adding coefficients in front of the reactants and products. These coefficients are the stoichiometric coefficients.
