What is the pH of 100 mL of a buffer that is 0.5 M HCNO and 0.5 M CNO− when 100 mL of a 0.2 M NaOH solution is added? Assume the volumes are additive. Ka of HCNO is 3.5 × 10−4 .

Be sure to answer all parts. the following equilibrium constants were determined at 1123 k: c(s) + co2(g) ⇌ 2co(g) k'p = 1.30 × 1014 co(g) + cl2(g) ⇌ cocl2(g) k''p = 6.00 × 10−3 calculate the equilibrium constant at 1123 k for the reaction: c(s) + co2(g) + 2cl2(g) ⇌ 2cocl2(g) 4.68 × 10 9 (enter your answer in scientific notation.) write the equilibrium constant expression, kp:
