Maria and carla were hiking when maria tripped, fell, and sprained her ankle. carla took out the first-aid kit and unwrapped a cold pack. carla popped a vial that was inside the cold pack. the two chemicals inside the pack mixed together and the pack began to get icy cold. carla applied the pack to maria's ankle. what kind of reaction occurred in the cold pack? what evidence supports your answer?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
