Balancing Chemical Equations
Chemical equations must be balanced with respect to all atoms and the atoms must exist in real compounds.
Balance equations by using the following rules...
1. Select the compound with the largest number of atoms of an element not including H or O or groups.
2. Balance this number of atoms with the corresponding atom on the other side of the equation with a coefficient (temporarily a fraction if necessary)...
never change the compound.3. Next balance any groups if they are present.
4. Now balance any H and O if they are present.
The first three examples are html tutorials and the other three are animated gif images.
