4. Steps in Balancing
Equations
1. Write the unbalanced chemical equation, make sure you
have followed correctly the rules in writing formulas of
compounds.
2. Take note of the elements present in the reactant and
product side.
3. Count the number of atom/s of each element present in
the reactant and product side.
4. Apply the Law of Conservation of Mass to get the same
number of atoms of every element on each side of the
equation.
