Question

In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide.

Part A
Enter a balanced chemical equation for this reaction.

Answer 1

Step-by-step explanation:

The balanced chemical equation for the reaction between solid sodium and liquid water to produce hydrogen gas and aqueous sodium hydroxide is:

2 Na (s) + 2 H2O (l) -> 2 NaOH (aq) + H2 (g)

In this reaction, two atoms of sodium (Na) react with two molecules of water (H2O) to produce two molecules of sodium hydroxide (NaOH) in aqueous form and one molecule of hydrogen gas (H2).
