Read each question carefully and provide the best answer. This worksheet will test your knowledge of classifying different types of chemical reactions.
1. Which type of reaction is represented by the general equation A + B → AB?
Decomposition reaction
Synthesis reaction
Single displacement reaction
Double displacement reaction
2. In the reaction 2KClO₃(s) → 2KCl(s) + 3O₂(g), what type of reaction is occurring?
Combination
Decomposition
Single replacement
Double replacement
3. A reaction where an element reacts with a compound, displacing another element from the compound, is called a reaction.
4. The products of a complete combustion reaction of a hydrocarbon are always and .
5. All redox reactions involve the transfer of electrons.
True
False
6. A precipitation reaction is a type of double displacement reaction.
True
False
7. Briefly describe the key difference between a single displacement reaction and a double displacement reaction.
8. Identify the type of reaction and balance the following chemical equation: C₃H₈ + O₂ → CO₂ + H₂O
Match each reaction type with its description.
9. Synthesis
a. One element replaces another in a compound.
10. Decomposition
b. Two or more reactants combine to form a single product.
11. Single Displacement
c. A compound breaks down into two or more simpler substances.
12. Double Displacement
d. Ions in two compounds switch places to form two new compounds.
