So i did a science lab today, and i am supposed to come up with the skeleton equation for it

The chemical reaction is decomposition (starting with one compound that will break off into 1 or more compounds after reaction)

This is what i have so far :
Cu (CO3) ---> CO2 + ____
i checked with the teacher and one of the products is Carbon Dioxide, but what is the second one?!
PLEASE HELP ME!
thanks!!

could it be CuO?

Thats what i was thinking! I'll go with that...thanks :)

To determine the second compound produced during the decomposition reaction, let's break down the chemical formula of Cu (CO3).

Cu (CO3) is copper carbonate. When copper carbonate decomposes, it breaks down into carbon dioxide (CO2) and the remaining compound, which is copper oxide (CuO).

Therefore, the correct skeleton equation for the decomposition of copper carbonate is:

Cu (CO3) --> CO2 + CuO

I hope this helps! Let me know if you have any further questions.
