Steps in Balancing Equations: Write the unbalanced chemical equation. Make sure you have followed correctly the rules in writing formulas of compounds. 1. Take note of the elements present in the reactant and product side. 2. Count the number of atom/s of each element present in the reactant and product side. 3. Apply the Law of Conservation of Mass to get the same number of atoms of every element on each side of the equation. Balance chemical equations by placing appropriate coefficients before the symbol or formula. Do not change the subscripts of the formula in an attempt to balance the equation as it will change the identity of the components. Activity 2. Balancing Act 1.

The Law of Conservation of Mass states that mass is conserved in a chemical
reaction. It means that the total mass of reactants is equal to the total mass of the
products. Chemical equations are balanced by placing the appropriate coefficients
before the symbols or formulas of reactants and products.
For example, when the methane (CHa) in natural gas combines with oxygen
(O2) in the air and burns, carbon dioxide (CO2) and water (HO) are formed.

The balanced chemical equation for this reaction is:
CH4() + 202(g) → CO2(g) + 2H20(@)
To get a clearer view of the number of atoms of each kind, look at the table
below
Kind of Atom
No. on Left side
No. on Right side
C
2 x 2 = 4
2 + 1(2) = 4
4
2 x 2 = 4
Steps in Balancing Equations:
Write the unbalanced chemical equation. Make sure you have followed correctly the
rules in writing formulas of compounds.
1. Take note of the elements present in the reactant and product side.
2. Count the number of atom/s of each element present in the reactant and product
side.
3. Apply the Law of Conservation of Mass to get the same number of atoms of
every element on each side of the equation. Balance chemical equations by placing
appropriate coefficients before the symbol or formula. Do not change the
subscripts of the formula in an attempt to balance the equation as it will change the
identity of the components.
