The reactants of two reactions are shown.

Reaction 1: Fe and HCl

Reaction 2: Cu and AgNO3

Which reaction is likely to be a redox reaction?

A. Both, because the charge on chloride ions and nitrate ions will change in the respective reactions

B. Both, because iron and copper will form their ions in those reactions

C. Only Reaction 2, because one of the products will be a metal

D. Only Reaction 1, because one of the products will be a gas

The answer to your question is letter B.

Step-by-step explanation:

The correct answer is letter B because both Copper and Iron as reactants have an oxidation number of zero and when they have reacted their oxidation numbers would be different from those.

A redox reaction is a reaction that involves a transfer of electrons from one atom to another and the oxidation numbers of the reactants are different from the oxidation numbers from the products.
