Balanced equation
![Balance the chemical equation algebraically: SO_3 + BeO ⟶ BeSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 SO_3 + c_2 BeO ⟶ c_3 BeSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for O, S and Be: O: | 3 c_1 + c_2 = 4 c_3 S: | c_1 = c_3 Be: | c_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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | SO_3 + BeO ⟶ BeSO_4](../image_source/7cc8719a5bf1e831773faf9889f01185.png)
