Sodium hydride reacts with excess water to produce aqueous sodium hydroxide and hydrogen gas: nah (s) h2o (l) → naoh (aq) h2 (g)a sample of nah weighing g will produce 982 ml of gas at 28.0 °c and 765 torr, when the hydrogen is collected over water. the vapor pressure of water at this temperature is 28 torr.

What is the measured amount of a product obtained from a chemical reaction?

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:
