... There are N of the above equations, one for each element (atom type) in the reaction. Generally there are M coefficients to find using the N equations. Unfortunately, in most chemical equations, M > N. Usually, we have the case that M = N+1. Thus, we need to find one additional equation. One simple ...

13.2 Chemical Formulas
... Chemical formulas have two important parts: chemical symbols for the elements in the compound and subscripts that tell how many atoms of each element are needed to form the compound. The chemical formula for water, H2O, tells us that a water molecule is made of the elements hydrogen (H) and oxygen ( ...
