which of the product is more likely to produce after thermal decomposition of CuCO3?

Question

Cu2O
or CuO

equations
CuCO3 → CO2 + CuO
2CuCO3 → 2CO2 + Cu2O + 1/2O2

Answer 1

CuO is more likely to be produced.
My classes do this experiment and it tests positive for CO2 afterwords. The remaining product is very similar in color and texture to CuO produced in a different manner.
