Classify the chemical reactions into various types depending on the way the products are formed by giving suitable examples.

Explanation

To classify chemical reactions into various types based on how the products are formed, we can outline the following categories along with suitable examples:

### Step 1: Chemical Combination Reaction
- **Definition**: A chemical combination reaction occurs when two or more reactants combine to form a single product.
- **Example**:
- When hydrogen gas (H₂) combines with chlorine gas (Cl₂), they form hydrochloric acid (HCl):
\[
\text{H}_2 + \text{Cl}_2 \rightarrow \text{2HCl}
