The reaction of metal with acid results in the formation of

Options

A. only Hydrogen gas
B. only salt
C. both salt and hydrogen gas
D. none of these

Explanation

**Step-by-Step Solution:**

1. **Identify the Reactants**: When a metal reacts with an acid, the reactants are the metal (e.g., sodium) and the acid (e.g., hydrochloric acid, HCl).

2. **Understand the Reaction**: The general reaction between a metal and an acid can be represented as:
\[ \text{Metal} + \text{Acid} \rightarrow \text{Salt} + \text{Hydrogen gas} \]

3. **Example Reaction**: Let's take sodium (Na) reacting with hydrochloric acid (HCl) as an example:
\[ \text{Na} + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2 \]
Here, sodium chloride (NaCl) is the salt formed, and hydrogen gas (H₂) is released.

4. **Formation of Products**: In the reaction, the metal displaces hydrogen from the acid, leading to the formation of a salt (NaCl) and the release of hydrogen gas (H₂).

5. **Conclusion**: Therefore, the reaction of metal with acid results in the formation of both a salt and hydrogen gas.

**Final Answer**: The reaction of metal with acid results in the formation of both salt and hydrogen gas.
