Question

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

Write a balanced chemical equation for this reaction.Express your answer as a chemical equation. Identify all of the phases in your answer.

Answer 1

Very Good Question .

Thanks for asking it !!!

Sodium is a highly reactive metal which reacts vigorously with water to form sodium hydroxide and Hydrogen gas  .

The balanced chemical equation :

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

Explanation :

Reaction of sodium with water is highly exothermic , so lot of heat is released with this heat hydrogen gets Combusted and we can see sodium metal catches fire and starts burning.

Hence Sodium metal is always stored in Kerosene.

Answer 2

The reaction will be -

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

Since Sodium is highly reactive in nature, the water will have the exothermic reaction that means that heat will be released which will form the sodium hydroxide and hydrogen gas which will combust.
