Answer:

sorry can't help

Explanation:

i stupid
No, the law of conservation of mass says that mass can not be created or destroyed only converted. After the copper carbonate was heated, the total amount of mass decreased. There is not an explanation for the difference in mass, therefore the law of conservation of mass did not hold true.
