sodium hydroxide, NaOH, and gives off hydrogen gas, H.
Write a balanced symbol equation, including state symbols,
for this reaction.

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

Explanation:

In the reaction above, solid pieces of sodium metal, Na, is dissolved in liquid water to form a solution of its alkali

(sodium hydroxide, NaOH) and gives off hydrogen gas, H.

The reaction occurs vigorously giving off hydrogen gas due to the highly reactive nature of alkali metals like sodium with water.
