Read each question carefully and provide your answer in the space provided. For multiple-choice questions, circle the best answer. For fill-in-the-blank questions, complete the statement with the correct term. For short-answer questions, explain your reasoning clearly.
1. Which type of reaction involves two or more reactants combining to form a single, more complex product?
Decomposition
Synthesis
Single Displacement
Combustion
2. In a single displacement reaction, a more reactive element replaces a less reactive element in a compound. Which of the following is an example of a single displacement reaction?
2Na + Cl₂ → 2NaCl
CaCO₃ → CaO + CO₂
Zn + 2HCl → ZnCl₂ + H₂
HCl + NaOH → NaCl + H₂O
3. A reaction where a compound breaks down into two or more simpler substances is called a reaction.
4. The reaction of a substance with oxygen, often producing heat and light, is known as a reaction.
5. In a double displacement reaction, the cations of two different compounds switch places.
True
False
6. A combustion reaction always produces carbon dioxide and water.
True
False
7. Briefly describe the main difference between a single displacement reaction and a double displacement reaction.
