Chemical reactions can be classified in various ways, but a common classification includes two main types: **combination reactions** and **decomposition reactions**. Here’s a brief description and examples of each:
### 1. Combination Reaction
In a combination reaction (also known as a synthesis reaction), two or more substances combine to form a single compound.
**Example:**
\[ \text{A} + \text{B} \rightarrow \text{AB} \]
A common example is the reaction between hydrogen gas and oxygen gas to form water:
\[ 2H_2(g) + O_2(g) \rightarrow 2H_2O(l) \]
### 2. Decomposition Reaction
In a decomposition reaction, a single compound breaks down into two or more simpler substances.
**Example:**
\[ \text{AB} \rightarrow \text{A} + \text{B} \]
A classic example is the decomposition of water into hydrogen and oxygen gases:
\[ 2H_2O(l) \rightarrow 2H_2(g) + O_2(g) \]
These examples illustrate the fundamental processes involved in combination and decomposition reactions.
