What describes the change in oxidation states of the following reaction? cu2+ reduces to cu, and al oxidizes to ai3+. cu2+ oxidizes to cu, and al reduces to ai3+. cu2+ is the reducing agent, and al is the oxidizing agent. cu is the reducing agent, and ai3+ is the oxidizing agent.

The reaction is

Cu⁺²(aq) ---> Cu(s)  [reduction]

The species which undergoes reduction is able to oxidize other one thus will called as "oxidizing agent"

Thus Cu⁺² is an oxidizing agent

or Cu is a reducing agent

Al(s)  ---> Al⁺³(aq)

Aluminium is undergoing oxidation

Thus is able to reduced others and hence is a reducing agent

Al is a reducing agent

or Al⁺³ is an oxidizing agent

Cu is the reducing agent, and AI3+ is the oxidizing agent.

D. Cu is the reducing agent, and AI3+ is the oxidizing agent.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
