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.

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
