1 answer
In the chemical reaction \( 4 \text{Fe} + 3 \text{O}_2 \rightarrow 2 \text{Fe}_2\text{O}_3 \), the correct answer is:
They are rearranged.
During a chemical reaction, the atoms are not lost or gained, but rather rearranged to form new substances, which in this case is the product \( \text{Fe}_2\text{O}_3 \).
