1) The first reaction is a series of chemical reactions involving copper. CuSO4 (copper sulfate) reacts with Cu(OH)2 (copper hydroxide) to form CuO (copper oxide) and water, and then CuO reacts with Cu to form copper metal. This is an example of a displacement reaction where a more reactive metal displaces a less reactive metal in a compound.

2) The second reaction is a series of chemical reactions involving zinc. ZnCl2 (zinc chloride) reacts with Zn(OH)2 (zinc hydroxide) to form ZnCl2 (zinc chloride) again. This is an example of a double displacement reaction where the cations and anions in the reactants switch partners to form new compounds.
