Balancing chemical equations notes
... chemicals are combined together and what chemicals are made when a reaction occurs. The law of conservation of mass says that matter can neither be created nor destroyed, and this requires that all chemical reactions be balanced. Consider the following balanced equation: Cu (s) + 4 HNO3 (aq) Cu(NO ...
