NaOH + ZnO = H2O + Na2ZnO2

sodium hydroxide + zinc oxide ⟶ water + Na2ZnO2

Balance the chemical equation algebraically: + ⟶ + Na2ZnO2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 Na2ZnO2 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O and Zn: H: | c_1 = 2 c_3 Na: | c_1 = 2 c_4 O: | c_1 + c_2 = c_3 + 2 c_4 Zn: | c_2 = c_4 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 1 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 + ⟶ + Na2ZnO2
