Read each question carefully and answer to the best of your ability. This worksheet covers the five main types of chemical reactions: synthesis, decomposition, single displacement, double displacement, and combustion.
1. In which type of reaction do two or more reactants combine to form a single, more complex product?
Decomposition reaction
Synthesis reaction
Single displacement reaction
Combustion reaction
2. Which of the following is characteristic of a combustion reaction?
A single reactant breaks down into simpler products.
Elements switch places in two different compounds.
A substance reacts with oxygen, often producing heat and light.
A more reactive element displaces a less reactive element from a compound.
3. A chemical reaction where a single compound breaks down into two or more simpler substances is called a reaction.
4. In a displacement reaction, a more reactive element replaces a less reactive element in a compound.
5. The general form for a double displacement reaction is AB + CD → + .
6. All combustion reactions involve the rapid reaction with oxygen, producing only carbon dioxide and water.
True
False
7. A single displacement reaction always results in the formation of a precipitate.
True
False
8. Balance the following chemical equation and identify the type of reaction: Fe + O₂ → Fe₂O₃
9. Describe the key difference between a single displacement reaction and a double displacement reaction.
Match each reaction type with its general equation.
10. Synthesis
a. AB + CD → AD + CB
11. Decomposition
b. A + BX → AX + B
12. Single Displacement
c. AB → A + B
13. Double Displacement
d. A + B → AB
