GPT-4o mini
A combination reaction, also known as a synthesis reaction, is a type of chemical reaction in which two or more reactants combine to form a single product. This process typically involves elements or simpler compounds joining together to create more complex substances.
**Example of a Combination Reaction:**
One common example of a combination reaction is the formation of water from hydrogen and oxygen gases:
\[
2H_2(g) + O_2(g) \rightarrow 2H_2O(l)
\]
In this reaction, two molecules of hydrogen gas combine with one molecule of oxygen gas to produce two molecules of liquid water.
