Calculate the mass of iron which will be converted into its oxide `(Fe_(3)O_(4))` by the action of 18 g of steam on it.

Explanation

To solve the problem of calculating the mass of iron that will be converted into its oxide (Fe₃O₄) by the action of 18 g of steam, we can follow these steps:

### Step 1: Write the balanced chemical equation
The reaction between iron (Fe) and steam (H₂O) to form iron(II,III) oxide (Fe₃O₄) and hydrogen gas (H₂) can be represented as follows:

\[ 3 \text{Fe} + 4 \text{H}_2\text{O} \rightarrow \text{Fe}_3\text{O}_4 + 4 \text{H}_2 \]
