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?

 

[AGNuke]

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

 

[Borek]

I would put it as

Cu(OH)₂ -> CuO + H₂O

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