I need to write a balanced equation for this problem and am having difficulty doing so.

The question is this: use the mole ratio of CuO produced per mole of malachite to write a balanced equation for the malachite decomposition reaction. Assume that CO2 is also a product of the decomposition.

Here are my numbers

moles of CuO produced 141.57

moles of malachite in 1g 221.12

Predict the mass of CuO expected to result from the decomposition of the malachite, based on the balanced equation.

Compare the mass obtained from the mass predicted, and give reasons for discrepancy.

Suggest a way to demonstrate that CO2 is a product of the reaction.
