To solve the given problem step by step, we will analyze the reactions involving zinc, sodium hydroxide, and hydrogen sulfide. ### Step 1: Reaction of Zinc with Sodium Hydroxide When zinc reacts with sodium hydroxide (NaOH), it forms a salt and releases a gas. The chemical equation for this reaction is: \[ \text{Zn} + 2 \text{NaOH} \rightarrow \text{Na}_2\text{ZnO}_2 + \text{H}_2 \] Here, the salt formed is sodium zincate (\(\text{Na}_2\text{ZnO}_2\)) and the gas released is hydrogen (\(H_2\)). ...
