Input interpretation

Balanced equation

Balance the chemical equation algebraically: O_2 + N_2 ⟶ N3O2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 O_2 + c_2 N_2 ⟶ c_3 N3O2 Set the number of atoms in the reactants equal to the number of atoms in the products for O and N: O: | 2 c_1 = 2 c_3 N: | 2 c_2 = 3 c_3 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 = 3/2 c_3 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 2 c_2 = 3 c_3 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 O_2 + 3 N_2 ⟶ 2 N3O2
