1. Which of the following factors does NOT typically increase the rate of a chemical reaction?
Increasing temperature
Increasing surface area
Decreasing reactant concentration
Adding a catalyst
2. A chemical reaction that absorbs energy from its surroundings is called an reaction.
3. The minimum amount of energy required to initiate a chemical reaction is known as the energy.
4. Describe two observable signs that indicate a chemical reaction has occurred.
5. In a combustion reaction, oxygen is always a reactant.
True
False

6. Synthesis
a. AB + C → AC + B
7. Decomposition
b. A + B → AB
8. Single Displacement
c. AB + CD → AD + CB
9. Double Displacement
d. AB → A + B
10. Consider the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH). Write the balanced chemical equation for this reaction and identify the type of reaction.
