`3Fe(s)+4H_(2)O(g)rarrFe_(3)O_(4)(s)+4H_(2)(g)`
1. Iron metal is getting oxidised.
2.Water is getting reduced.
3.Water is acting as reducing agent.
4.Water is acting as oxidising agent.

Options

A. `1, 2 and 3`
B. `3and4`
C. `1, 2 and 4`
D. `2 and 4`

Explanation

To determine which statements about the reaction \(3Fe(s) + 4H_2O(g) \rightarrow Fe_3O_4(s) + 4H_2(g)\) are correct, we will analyze the oxidation and reduction processes involved in the reaction.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- Reactants: Iron (Fe) and Water (H₂O)
- Products: Iron(II,III) oxide (Fe₃O₄) and Hydrogen gas (H₂)

2. **Determine Oxidation States**:
- In elemental form, the oxidation state of Iron (Fe) is 0.
- In Fe₃O₄, the oxidation state of Iron is +2 and +3 (average +2.67).
- In water (H₂O), the oxidation state of Oxygen is -2 and Hydrogen is +1.
- In Hydrogen gas (H₂), the oxidation state is 0.

3. **Identify Oxidation and Reduction**:
- **Oxidation**: The process where a substance loses electrons or increases its oxidation state. Here, Fe (0) is oxidized to Fe₃O₄ (+2, +3).
- **Reduction**: The process where a substance gains electrons or decreases its oxidation state. Here, H₂O (O -2) is reduced to H₂ (0) as it loses oxygen.

4. **Analyze Each Statement**:
- **Statement 1**: "Iron metal is getting oxidised."
- Correct. Iron is changing from 0 to +2 and +3 in Fe₃O₄.
- **Statement 2**: "Water is getting reduced."
- Correct. Water is losing oxygen and forming hydrogen gas.
- **Statement 3**: "Water is acting as reducing agent."
- Incorrect. Water is being reduced, so it acts as an oxidizing agent.
- **Statement 4**: "Water is acting as oxidising agent."
- Correct. Since water is being reduced, it is acting as an oxidizing agent.

5. **Conclusion**:
- The correct statements are 1, 2, and 4. Therefore, the correct answer is that statements 1, 2, and 4 are correct.

### Final Answer:
The correct statements are:
1. Iron metal is getting oxidised.
2. Water is getting reduced.
4. Water is acting as oxidising agent.
