Solution
Chemical equations are symbolic representations of chemical reactions that express the reactants and products in terms of their chemical formulae. Example: burning of coal in air Coal + Oxygen → Carbon dioxide C(s) + O2(g) → CO2(g)
According to the law of conservation of mass, “matter can neither be created nor destroyed”. Thus, a chemical equation must always be balanced.
