Answer

It seems that the provided video transcript does not relate to the chemistry question regarding reactions that produce water. However, I can still provide a step-by-step text solution for the question "What is a reaction in which one of the products is water?"

### Step-by-Step Solution:

1. **Understanding Chemical Reactions**:
- A chemical reaction involves the transformation of reactants into products. In some reactions, one of the products formed is water (H₂O).

2. **Identifying Types of Reactions**:
- There are several types of chemical reactions, but one common type that produces water is a **combination reaction** or **synthesis reaction**.

3. **Example of a Reaction Producing Water**:
- A classic example of a reaction that produces water is the combustion of hydrocarbons. For instance, when methane (CH₄) combusts in the presence of oxygen (O₂), the products are carbon dioxide (CO₂) and water (H₂O).
- The balanced chemical equation for this reaction is:
\[ CH₄ + 2O₂ \rightarrow CO₂ + 2H₂O \]

4. **Acid-Base Neutralization**:
- Another example is an **acid-base neutralization reaction**. When an acid reacts with a base, water is formed along with a salt. For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the products are sodium chloride (NaCl) and water (H₂O).
- The balanced chemical equation is:
\[ HCl + NaOH \rightarrow NaCl + H₂O \]

5. **Conclusion**:
- In summary, reactions that produce water include combustion reactions and acid-base neutralization reactions. These reactions are fundamental in chemistry and illustrate the formation of water as a product.
