In the following reaction which occurs from left to right: 2 Fe3+(aq) + Zn(s) → 2 Fe2*(aq) + Zn2*(aq) 3+ Zn(s) is the reducing agent and Fe*(aq) is the oxidizing agent. O Zn(s) is the reducing agent and Zn2*(aq) is the oxidizing agent. O Fe3+(aq) is the reducing agent and Fe2*(aq) is the oxidizing agent. O Fe3*(aq) is the reducing agent and Zn(s) is the oxidizing agent.

When a solution of hydrochloric acid is added to silver nitrate dissolved in water, a white precipitate called silver chioride is produced along with nitric acid which is highly corrosive. This is best represented by which chemical equation? O HCI (aa) - AGNO3 (ax) -→ AgCi (1) - H3N (ag) O HCI (ag) • AGNO3 (a) --→ AgCi (1) - HON(aq) O HCI (an) - AgNO3 (aa) --→ AgCI (1) - HNO3 (aq) O HCI (aq) + AGNO3 (a9) --> AgCI (1) + HNO3
