The reaction 2 Cu + O2 ? 2 CuO has long been called an oxidation-reaction. Copper also reacts with chlorine: Cu + Cl2 ? CuCl2. In such a reaction:. a. Copper is also oxidized even though no oxygen is present. b. Chlorine is oxidized. c. Oxidation occurs, but reduction does not. d. There is no change in oxidation numbers.

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

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:
