Explanation:
A balanced reaction is a reaction where there are equal number of atoms on both reactant and product side.
For example, [tex]2C_{8}H_{18} + O_{2} \rightarrow CO_{2} + H_{2}O[/tex]
Number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
Therefore, in order to balance the equation we multiply [tex]O_{2}[/tex] by 25 on reactant side and multiply [tex]CO_{2}[/tex] by 16 and [tex]H_{2}O[/tex] by 18.
Thus, the balanced chemical equation will be as follows.
[tex]2C_{8}H_{18} + 25O_{2} \rightarrow 16CO_{2} + 18H_{2}O[/tex]
