Ca(OH)2CO2 ⟶ CaCO3H2O
Balanced equation
Balance the chemical equation algebraically: Ca(OH)2CO2 ⟶ CaCO3H2O Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Ca(OH)2CO2 ⟶ c_2 CaCO3H2O Set the number of atoms in the reactants equal to the number of atoms in the products for Ca, O, H and C: Ca: | c_1 = c_2 O: | 4 c_1 = 4 c_2 H: | 2 c_1 = 2 c_2 C: | c_1 = c_2 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | Ca(OH)2CO2 ⟶ CaCO3H2O
