A student determines the composition of a copper chloride compound. Tell whether each of the situations described below would cause the student’s experimental value for the percent of copper in the compound to be greater than less than, or unchanged from the theoretical value. Explain.

a. The student fails to heat to constant mass thereby leaving some water in the copper product

b. the student heats the copper product too long turning the product green and indicating the formation of some copper(II) carbonate.
