According to this graph, which statement describes how the amount of copper changes over time in the reaction CuO + H2 → Cu + H2O? The amount of the product Cuincreases rapidly at first and then continues to increase slowly.

The amount of the reactant CuOincreases rapidly at first and then continues to increase slowly.

As time passes there is steady decrease in the amount of Cu.

As time passes CuOand Cuwill reach a dynamic equilibrium.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Most metamorphosis processes take place
