Balancing Chemical Equations
"Simple" Reactions In many instances some simple rules can be employed to balance chemical reactions. These are listed below:
- Look for elements that only occur in one compound on each side of the equation and balance those first.
- Look for groups of atoms (polyatomic ions) that remain intact from one side of the equation to the other, balance these groups as a unit.
- If a reactant or product is present as a free element or monoatomic substance (e.g. Ca(s) or N2(g)) balance that last.
Redox Reactions (i.e. reactions that involve transfer of electrons)
