Checking the balanced equation: Left side: Fe = 3, H = 4 2 = 8, O = 4 1 = 4 Right side: Fe = 3, H = 4 2 = 8, O = 4 The number of atoms of each element is equal on both sides.
Which one of the following equations is the balanced chemical equation for the given reaction ? $\text{Fe + H}_2\text{O} \rightarrow \text{Fe}_3\text{O}_4\text{ + H}_2$
