Solution
When sodium hydroxide solution is heated with zinc, then sodium zincate and hydrogen gas are formed.
\[\ce{\underset{(Base)}{\underset{Sodium hydroxide}{2NaOH_{(aq)}}} + \underset{Zinc}{{Zn}_{(s)}} ->[Heat] \underset{(Salt)}{\underset{Sodium zincate}{Na2ZnO2_{(aq)}}} + \underset{Hydrogen}{H2_{(g)}}}\]
