Decomposition
Synthesis
Single Displacement
Double Displacement
2. The reaction 2KClO₃(s) → 2KCl(s) + 3O₂(g) is an example of a:
Synthesis reaction
Combustion reaction
Decomposition reaction
Single displacement reaction
3. In a single displacement reaction, one element replaces another element in a .
4. A double displacement reaction typically occurs between two compounds in aqueous solution.
5. A combustion reaction always involves a substance reacting with , usually producing heat and light.
6. Briefly describe the main difference between a single displacement reaction and a double displacement reaction.
7. All chemical reactions involve the breaking and forming of chemical bonds.
True
False
8. A precipitation reaction is a specific type of double displacement reaction.
True
False
Match the reaction type with its general equation.
9. Synthesis
a. AB → A + B
10. Decomposition
b. A + BX → AX + B
11. Single Displacement
c. AX + BY → AY + BX
12. Double Displacement
d. A + B → AB
