Question

Balance the following equations:
(i) Fe (s) + H2O (g) → Fe3O4 (s) + H2 (g)
(ii) C6H12O6 (aq) + O2 (aq) → CO2 (aq) + H2O (l)

Hint:

In balancing equations, ensure that the number of atoms of each element is the same on both sides.

Answer 1

(i) The balanced equation for the reaction is:
\[ 3 \text{Fe (s)} + 4 \text{H}_2\text{O (g)} \rightarrow \text{Fe}_3\text{O}_4 (s) + 4 \text{H}_2 (g) \]
(ii) The balanced equation for the reaction is:
\[ \text{C}_6\text{H}_{12}\text{O}_6 (aq) + 6 \text{O}_2 (aq) \rightarrow 6 \text{CO}_2 (aq) + 6 \text{H}_2\text{O} (l) \]
