(a) c) Did the copper ion lose electrons or gain electrons to become copper metal? ained euehvin

Solution

a) reduction- reduction is the gaining of electrons by atoms in chemical reaction

b) oxidation - oxidation is the loss of electrons by atoms in a chemical reaction

c) activity series - It is the rank of metals in decreasing order of ability to displace hydrogen gas from acids and water

d) Single Displacement Reaction - It is a type of chemical reaction where an element reacts with a compound and replaces another element of that compound.

2) a The charge of Cu in CusO4 is +2

b) The charge of Cu metal is 0

C) Cu gained electrons to become Cu metal.
