Consider the following equilibria: 2 SO3(g) ⇌ 2 SO2(g) + O2(g) Kc = 2.3 × 10–7 2 NO3(g) ⇌ 2 NO2(g) + O2(g) Kc = 1.4 × 10–3 Calculate the equilibrium constant for the reaction: SO3(g) + NO2(g) ⇌SO2(g) + NO3(g)

Identify the balanced chemical equation that represents a decomposition reaction. p4 + 3o2 ⟶ p2o3 2fe(oh)3 ⟶ 2feo3 + h2o cuso4 ⟶ cuo + 2so3 2fe(oh)3 ⟶ fe2o3 + 3h2o

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?
