Calculate the overall energy change in kJ/mol for the reaction.

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

At room temperature what happens to the average kinetic energy of the molecules of a solid, liquid, and a gas

Consider the equilibrium system: 2icl(s) ⇄ i2(s) + cl2(g) which of the following changes will increase the total amount of of cl2 that can be produced? all of the listed answers are correct decreasing the volume of the container removing the cl2 as it is formed adding more icl(s) removing some of the i2(s)
