Read each question carefully and follow the instructions to identify the type of chemical reaction. Write your answers in the spaces provided.
1. Which type of reaction combines two or more reactants to form a single, more complex product?
Decomposition
Synthesis
Single Displacement
Combustion
2. In a reaction, a compound breaks down into two or more simpler substances.
3. A reaction where an element reacts with a compound, displacing another element from the compound, is called a reaction.
4. All combustion reactions involve oxygen as a reactant and produce carbon dioxide and water.
True
False
5. Identify the type of reaction represented by the following chemical equation and explain your reasoning: 2Na + Cl₂ → 2NaCl
Match each reaction type with its general form.
1. Synthesis
a. AB → A + B
2. Decomposition
b. A + BX → AX + B
3. Single Displacement
c. AX + BY → AY + BX
4. Double Displacement
d. A + B → AB
6. Consider the reaction: CH₄ + 2O₂ → CO₂ + 2H₂O. What type of reaction is this, and what are the key characteristics that allow you to identify it?
