✓ Answer:
D
Hydrogen gas and sodium hydroxide solution are produced.
When sodium metal reacts with water, it produces hydrogen gas and sodium hydroxide solution. The reaction is highly exothermic, meaning it releases heat, and the hydrogen gas formed can ignite, producing a yellow flame. The balanced chemical equation for this reaction is: 2Na + 2H2O → 2NaOH + H2. This is a common demonstration to show the reactivity of sodium, an alkali metal, with water.
