Read each question carefully and provide the best answer. This worksheet will test your knowledge of 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. The reaction: 2Na + Cl₂ → 2NaCl is an example of a:
Decomposition reaction
Combustion reaction
Synthesis reaction
Single displacement reaction
3. In a decomposition reaction, a single compound breaks down into two or more simpler .
4. A single displacement reaction occurs when one element replaces another element in a .
5. Combustion reactions typically involve a substance reacting with oxygen to produce heat and .
6. A double displacement reaction always produces a precipitate.
True
False
7. Oxidation-reduction reactions are also known as redox reactions.
True
False
8. Balance the following chemical equation and identify the type of reaction: Fe + O₂ → Fe₂O₃
9. Describe the key characteristics of a combustion reaction.
Match each reaction type with its general form.
