Model Answer

When ethanol reacts with sodium metal, the two products formed are sodium ethoxide (CH₃CH₂O⁻Na⁺) and hydrogen gas (H₂).

Explanation

The equation from the textbook directly gives both products: `2Na + 2CH₃CH₂OH → 2CH₃CH₂O⁻Na⁺ + H₂`. Examiners expect both products named; writing the chemical formula alongside the name is ideal for 1 mark.
