♦ Relevant knowledge

Chemical equations are an expression of the chemical elements involved in a chemical reaction by using symbols and the formula for the chemical compound. The coefficients of the equation indicate the number of molecules, atoms, or moles belonging to the species. When balancing a chemical equation we alter the coefficients in that the amount of every atom is the same on each side of the equation. We have to balance this equation due to the Law of conservation of mass.
