Input interpretation
activated charcoal + potassium nitrate ⟶ carbon dioxide + nitrogen + pearl ash
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 Set the number of atoms in the reactants equal to the number of atoms in the products for C, K, N and O: C: | c_1 = c_3 + c_5 K: | c_2 = 2 c_5 N: | c_2 = 2 c_4 O: | 3 c_2 = 2 c_3 + 3 c_5 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_4 = 1 and solve the system of equations for the remaining coefficients: c_1 = 5/2 c_2 = 2 c_3 = 3/2 c_4 = 1 c_5 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 5 c_2 = 4 c_3 = 3 c_4 = 2 c_5 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 5 + 4 ⟶ 3 + 2 + 2
