Identify the gas in the following :
Gas produced by the action of dilute nitric acid on zinc .

Explanation

To identify the gas produced by the action of dilute nitric acid on zinc, we can follow these steps:

### Step 1: Write the Reactants
The reactants in this reaction are zinc (Zn) and dilute nitric acid (HNO3).

### Step 2: Identify the Products
When zinc reacts with dilute nitric acid, it forms zinc nitrate (Zn(NO3)2) and a gas. The reaction can be represented as:
\[ \text{Zn} + \text{HNO}_3 \rightarrow \text{Zn(NO}_3\text{)}_2 + \text{Gas} + \text{H}_2\text{O} \]
