Question

I need helping understanding this single replacement.CuO(s)+H2(g)I thought it would be Cu(Hu(g)+O(g)Why is it Cu(s)+H2O(g)? can you show meand why is H2O a gas and not a liquid (l)here?

Answer 1

Step-by-step explanation:

The complete reaction of CuO(s) + H2(g) should be Cu(s) + H2O (l)

CuH does not exist. Solid Cu will form and oxygen will combine with H2 producing water.

Answer: CuO(s) + H2(g) --> Cu(s) + H2O (l)
