Read each question carefully and provide the best answer based on your knowledge of chemical reaction classifications.
1. Which type of reaction involves two or more reactants combining to form a single, more complex product?
Decomposition
Synthesis
Single Displacement
Combustion
2. The reaction 2AgNO₃(aq) + Cu(s) → Cu(NO₃)₂(aq) + 2Ag(s) is an example of a:
Double Displacement
Decomposition
Single Displacement
Synthesis
1. In a combustion reaction, oxygen is always a reactant.
True
False
2. A precipitation reaction is a common type of single displacement reaction.
True
False
1. In a decomposition reaction, a single compound breaks down into two or more substances.
2. Double displacement reactions often result in the formation of a precipitate, a gas, or .
1. Describe the key difference between a single displacement reaction and a double displacement reaction.
Match each reaction type with its general equation.
1. Synthesis
a. AX + BY → AY + BX
2. Decomposition
b. A + B → AB
3. Single Displacement
c. AB → A + B
4. Double Displacement
d. A + BC → AC + B
