Why is it important to balance chemical equation?

  • Chemical equations are balanced so as to obey the law of conservation of mass.

In this case; the balanced chemical equation for the reaction between carbon monoxide and oxygen gas is given by;

2CO(g) + O₂(g) → 2CO₂(g)

  • This is because there are 2 carbon atoms and 4 oxygen atoms on both the reactant and product side.
