Read each question carefully and provide the best answer. This worksheet covers different types of chemical reactions.
1. Which type of reaction involves two or more reactants combining to form a single, more complex product?
Decomposition reaction
Synthesis reaction
Single displacement reaction
Double displacement reaction
2. In the reaction: A + BC → AC + B, what type of reaction is this?
Synthesis
Decomposition
Single displacement
Double displacement
3. A reaction that involves a substance reacting with oxygen, often producing heat and light, is called a reaction.
4. In a reaction, two ionic compounds exchange ions to form two new compounds.
5. Describe the key characteristics that distinguish a decomposition reaction from a synthesis reaction.
6. An acid-base reaction is a type of double displacement reaction.
True
False
Match the reaction type with its general equation.
7. Synthesis
a. AB → A + B
8. Decomposition
b. A + B → AB
9. Single Displacement
c. AB + CD → AD + CB
10. Classify the following chemical reaction:
2Na(s) + Cl2(g) → 2NaCl(s)
