Which of the following product(s) obtained when iron reacts with steam?

Options

A. `FeO+H_(2)`
B. `Fe_(2)O_(3)+H_(2)`
C. `Fe_(2)O_(3)+O_(2)`
D. `Fe_(3)O_(4)+H_(2)`

Answer

To determine the products obtained when iron reacts with steam, we can follow these steps:

### Step 1: Understand the Reaction
When a metal reacts with steam (water in its gaseous state), it typically forms a metal oxide and hydrogen gas. This is a common reaction for metals, particularly for those that can displace hydrogen from water.

### Step 2: Identify the Reactants
In this case, the reactants are:
- Iron (Fe)
- Steam (H₂O in gaseous form)

### Step 3: Write the Chemical Equation
The general reaction can be represented as:
\[ \text{Metal} + \text{Steam} \rightarrow \text{Metal Oxide} + \text{Hydrogen Gas} \]

For iron, the reaction can be specifically written as:
\[ 3 \text{Fe} + 4 \text{H}_2\text{O} \rightarrow \text{Fe}_3\text{O}_4 + 4 \text{H}_2 \]

### Step 4: Identify the Products
From the balanced equation, we can see that the products of the reaction are:
- Iron(II,III) oxide (Fe₃O₄)
- Hydrogen gas (H₂)

### Step 5: Conclusion
Thus, the products obtained when iron reacts with steam are iron(II,III) oxide (Fe₃O₄) and hydrogen gas (H₂).

### Final Answer
The correct products obtained when iron reacts with steam are:
- Iron(II,III) oxide (Fe₃O₄)
- Hydrogen gas (H₂)
