Input interpretation
red phosphorus + rubidium ⟶ Rb3P
Balanced equation
Balance the chemical equation algebraically: + ⟶ Rb3P Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 Rb3P Set the number of atoms in the reactants equal to the number of atoms in the products for P and Rb: P: | c_1 = c_3 Rb: | 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 c_3 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + 3 ⟶ Rb3P
