Balanced equation
![Balance the chemical equation algebraically: H_2SO_4 + HNO_3 + SNi ⟶ H_2O + S + NO_2 + NiSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 HNO_3 + c_3 SNi ⟶ c_4 H_2O + c_5 S + c_6 NO_2 + c_7 NiSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, N and Ni: H: | 2 c_1 + c_2 = 2 c_4 O: | 4 c_1 + 3 c_2 = c_4 + 2 c_6 + 4 c_7 S: | c_1 + c_3 = c_5 + c_7 N: | c_2 = c_6 Ni: | c_3 = c_7 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_3 = c_2/8 + 3/4 c_4 = c_2/2 + 1 c_5 = 1 c_6 = c_2 c_7 = c_2/8 + 3/4 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_2 = 2 and solve for the remaining coefficients: c_1 = 1 c_2 = 2 c_3 = 1 c_4 = 2 c_5 = 1 c_6 = 2 c_7 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | H_2SO_4 + 2 HNO_3 + SNi ⟶ 2 H_2O + S + 2 NO_2 + NiSO_4](../image_source/01bb3e87c65eb9ffb431c15c5a4c6581.png)
