Study the reaction. 2AgNO3 (aq)+Cu (s)→Cu(NO3)2 (aq)+2Ag (s)
If the oxidation number of copper changes from 0 to +2, is this a redox reaction?

No; copper gained 2 electrons and was reduced.
Yes; copper lost 2 electrons and was oxidized.
Yes, the products have 2 fewer electrons than the reactants.
No, the products have as many electrons as the reactants.

Iknow the answer is a but i don't know why
