Balanced equation

Balance the chemical equation algebraically: O_2 + C_5H_10 ⟶ H_2O + CO_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 O_2 + c_2 C_5H_10 ⟶ c_3 H_2O + c_4 CO_2 Set the number of atoms in the reactants equal to the number of atoms in the products for O, C and H: O: | 2 c_1 = c_3 + 2 c_4 C: | 5 c_2 = c_4 H: | 10 c_2 = 2 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 15/2 c_2 = 1 c_3 = 5 c_4 = 5 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 15 c_2 = 2 c_3 = 10 c_4 = 10 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 15 O_2 + 2 C_5H_10 ⟶ 10 H_2O + 10 CO_2
