Carefully read each question and follow the instructions to identify the type of chemical reaction described or shown. Write your answers in the spaces provided.
1. Which type of reaction involves two or more reactants combining to form a single, more complex product?
Decomposition
Synthesis
Single Displacement
Double Displacement
2. The reaction 2KClO₃ → 2KCl + 3O₂ is an example of what type of reaction?
Combustion
Synthesis
Decomposition
Single Displacement
3. In a reaction, an element reacts with a compound, displacing another element from the compound.
4. A reaction that produces carbon dioxide and water from a hydrocarbon and oxygen is typically a reaction.
5. Identify the type of reaction and explain your reasoning for the following equation: AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
6. Describe the key characteristics that differentiate a synthesis reaction from a decomposition reaction.
7. A combustion reaction always requires oxygen as a reactant.
True
False
8. In a single displacement reaction, two elements swap places in their respective compounds.
True
False
Match each reaction type with its general form.
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
