H20+na

When water (H₂O) reacts with sodium (Na), it produces sodium hydroxide (NaOH) and hydrogen gas (H₂). The balanced chemical equation for this reaction is:

\[ 2 \text{Na} + 2 \text{H}_2\text{O} \rightarrow 2 \text{NaOH} + \text{H}_2(g) \]

In this reaction, sodium metal reacts vigorously with water, resulting in the formation of sodium hydroxide, which is a strong base, and hydrogen gas, which is released as bubbles. This reaction is exothermic, meaning it releases heat. It's important to handle this reaction caution, as the hydrogen gas released can ignite easily in the presence of a spark or flame.
