Question

Balance the following equations for both mass and charge. a. C3H8O (l) + O2 (g) ? CO2 (g) + H2O (l) b. K2S (aq) + Ni(NO3)2 (aq) ? KNO3 (aq) + NiS (s) c. As2O3 (s) + NO3-(aq) ? H3AsO4 (aq) + NO(g) (acid conditions) d. PCl3 (g) + NH3 (g) ? P(NH2)3 (g) + HCl (g) e. C3H6 (g) + NH3 (g) + O2 (g) ? C3H3N (g) + H2O (g)

Explanation / Answer

10 C3H8O + 25 O2 = 30 CO2 + 4 H20 K2S(aq) + Ni(NO3)2(aq) = 2 KNO3(aq) + NiS(s) 3(As2O3 + 5H2O --> 2H3AsO4 + 4H+ + 4e-) 4{4H+ + NO3- + 3e- --> NO + 2H2O) --------------------------------------… 16H+ + 3As2O3 + 4NO3- + 15H2O --> 6H3AsO4 + 4NO + 12H+ + 8H2O simplify 4H+ + 3As2O3 + 4NO3- + 7H2O --> 6H3AsO4 + 4NO 1PCl3 (g) +3NH3 (g) ==> 1P(NH2)3 (g) + 3HCl (g) That is the equation balanced. Now you gotta apply the equilibrium expression. 2C3H6(g) + 2NH3(g) + 3O2(g) ? 2C3H3N(g) + 6H2O(g)
