Input interpretation
potassium nitrate + soda ash + chromium(III) oxide ⟶ carbon dioxide + potassium nitrite + sodium chromate
Balanced equation
Balance the chemical equation algebraically: + + ⟶ + + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 + c_3 ⟶ c_4 + c_5 + c_6 Set the number of atoms in the reactants equal to the number of atoms in the products for K, N, O, C, Na and Cr: K: | c_1 = c_5 N: | c_1 = c_5 O: | 3 c_1 + 3 c_2 + 3 c_3 = 2 c_4 + 2 c_5 + 4 c_6 C: | c_2 = c_4 Na: | 2 c_2 = 2 c_6 Cr: | 2 c_3 = c_6 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 2 c_3 = 1 c_4 = 2 c_5 = 3 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 + 2 + ⟶ 2 + 3 + 2
