Iron reacts with steam to form

Options

A. `Fe_(2)O_(3)`
B. `Fe_(3)O_(4)`
C. `H_(2)`
D. Both B & C

Explanation

To solve the question "Iron reacts with steam to form," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are iron (Fe) and steam (H2O).

2. **Understand the Reaction**:
- When iron reacts with steam, it typically forms iron oxide and hydrogen gas.

3. **Determine the Products**:
- The primary product formed when iron reacts with steam is iron(II,III) oxide, which is represented as Fe3O4 (magnetite).
- Additionally, hydrogen gas (H2) is released as a byproduct of the reaction.

4. **Write the Balanced Chemical Equation**:
- The balanced equation for the reaction is:
\[ 3 \text{Fe} + 4 \text{H}_2\text{O} \rightarrow \text{Fe}_3\text{O}_4 + 4 \text{H}_2 \]
- This indicates that three moles of iron react with four moles of water to produce one mole of Fe3O4 and four moles of hydrogen gas.

5. **Identify the Correct Options**:
- From the options provided:
- Option 1: Fe2O3 (iron(III) oxide)
- Option 2: Fe3O4 (iron(II,III) oxide)
- Option 3: H2 (hydrogen gas)
- Option 4: B and C (Fe3O4 and H2)
- The correct products formed in this reaction are Fe3O4 and H2.

6. **Conclusion**:
- Therefore, the correct answer to the question is Option 4: B and C (Fe3O4 and H2).
