(a) Interpretation: Balance the following equation of HgO → Heat Hg+O 2 needs to be determined. Concept introduction: The equation in which the number of atoms for each element present in chemical reaction and total charge is the same for both products and reactants, the equation is known as balanced chemical equation. Steps to balance the chemical equation: 1.Identify reactants and products. 2. Write chemical formula. 3.Count number of atoms in reactant side and product side. 4. If number of atoms is not same then try to balance by changing the coefficient of molecules on either one side or both side of the equation.
