Balancing Chemical Equations
... Scientists use chemical equations as a shorthand way to represent the reactions that occur between substances. Because of the law of conservation of matter, these equations must be balanced. In other words, the number of atoms of each element must be conserved. For example, look at the reaction of h ...
