The question is with a lab that I have already done. Here are my numbers
moles of malachite in 1g 221.12
moles of CuO produced 141.57
ratio of moles of CuO produced per moles of malachite decomposed 79.55
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.
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 discuss reasons for any discrepancy.
Suggest a way to demonstrate that CO2 is a product of the reaction.
