3 Rules for writing Chemical Reactions

Really, the most important concepts are these:

1. Atoms tend toward stability, to have a complete set of valence electrons

2. Compounds must be neutrally charged

3. Chemical Equations balance: the number of atoms of reactants (their total mass) must equal the number of atoms of products (the product mass).

However, this short tutorial may be helpful in a more practical sense.
