Answer 2

Table of Reactions:

| Reactants/Metals | Fe (Iron) | Zn (Zinc) | Ag (Silver) | Al (Aluminum) | |------------------|-----------|-----------|-------------|---------------| | FeCl3 (Iron Chloride) | + | - | - | + | | ZnSO4 (Zinc Sulfate) | - | + | - | - | | AgNO3 (Silver Nitrate) | - | - | + | - | | AlCl3 (Aluminum Chloride) | + | - | - | + |

Note: The "+" sign indicates a possible reaction, while the "-" sign indicates no reaction is expected.

Explanation:

In the given table, we have different reactants/metals on the left column and various compounds on the top row. We need to determine the possibility of reactions between the reactants/metals and the compounds.

1. Fe (Iron) + FeCl3 (Iron Chloride): - Iron reacts with iron chloride to form iron(III) chloride. - Therefore, the reaction is expected to occur. (+)

2. Zn (Zinc) + ZnSO4 (Zinc Sulfate): - Zinc does not react with zinc sulfate. - Therefore, no reaction is expected. (-)

3. Ag (Silver) + AgNO3 (Silver Nitrate): - Silver reacts with silver nitrate to form silver chloride. - Therefore, the reaction is expected to occur. (+)

4. Al (Aluminum) + AlCl3 (Aluminum Chloride): - Aluminum reacts with aluminum chloride to form aluminum(III) chloride. - Therefore, the reaction is expected to occur. (+)
