solid copper (II) nitrate decomposes on heating to form solid copper (II) oxide, nitrogen dioxide gas and oxygen gas. WHAT IS THE BALANCED EQUATION. Please

I'll give you the species in an unbalanced equation:
Cu(NO_3)_2 \to CuO + NO_2 + O_2
Now you try balancing and see what you come up with. Then I'll help you if you get it wrong.

2Cu(NO3)2 gives when heated 2CuO + 4NO2 +O2

Looks right to me, well done :)
Do you understand how I derived the species in my first post?
