Question

Which of the following compounds will produce H2O as one of the products when it decomposes?

a.) Hg(ClO3)2
b.) Cu(OH) 2
c.) CaO
d.) MgCO3

Answer 1

B) Cu(OH) 2 Is the resulting answer when H20 is decomposed.

Answer 2

Cu(OH)2 will decompose to give water as one of the products

The decomposition reaction will be

Cu(OH)2(s) ----> CuO(s) + H2O(l)

Hence it is giving water as product
