    2. Relevant equations

    n/a

    3. The attempt at a solution

    I got the first 3 answers. But I don't know what this is asking for. What is CuO. Where did that come from. Is \n't it supposed to be Cu(OH)2?

    [itex]CuO + H_2O \rightarrow Cu(OH)_2[/itex]
    It is just hydrated form, nothing to worry about.

    I would put it as

    Cu(OH)2 -> CuO + H2O

    copper hydroxide easily decomposes, but copper oxide doesn't react with water.
