Question #cec2d

Answer 1

Regardless of the particular reaction taking place, each one mole of copper chloride must yield one mole of copper metal.

Explanation:

Although we do not have a complete description of a chemical reaction to look at, one can only assume that a process is being considered in which the `Cu^(2+)` ion in `CuCl_2` is being changed into copper metal.

This is necessarily a one-to-one reaction (based on conservation of atoms - you cannot produce more Cu atoms than the amount initially found in the compound!).

Since a mole of `CuCl_2` contains one mole of Cu atoms, for each one mole of copper chloride, you will obtain one mole of copper metal.
