State two physical properties of copper(II) chloride, apart from electrical conductivity.
Copper is a transition element. Suggest one property of copper(II) chloride that is characteristic of a compound of a transition element.
Copper reacts with chlorine to produce copper(II) chloride, $\text{Cu} + \text{Cl}_2 \rightarrow \text{CuCl}_2$. Copper(II) chloride contains $\text{Cu}^{2+}$ and $\text{Cl}^-$ ions. Explain, in terms of electron movement, how $\text{CuCl}_2$ is formed from copper atoms and chlorine molecules.
Copper(II) iodide breaks down to form iodine and copper(I) iodide. The ionic equation is $2\text{Cu}^{2+} + 4\text{I}^- \rightarrow 2\text{CuI} + \text{I}_2$. Use the information to explain that oxidation occurs.
Use the information to explain that reduction occurs.
A sample of copper(II) carbonate is heated strongly. State the products of this reaction.
