Read each question carefully and provide your answer in the space provided. For multiple-choice questions, circle the best answer. For classification questions, write the type of reaction.
Observe the image below, which depicts a thermite reaction, a highly exothermic redox reaction.
1. Which type of reaction involves two or more reactants combining to form a single product?
Decomposition
Synthesis
Single Displacement
Double Displacement
2. In a combustion reaction, what are the typical products when a hydrocarbon reacts with oxygen?
Hydrogen and Oxygen
Carbon Dioxide and Water
Carbon Monoxide and Hydrogen
Methane and Water
3. A reaction where a more reactive element displaces a less reactive element from its compound is called a reaction.
4. The process of losing electrons in a redox reaction is known as .
5. In a double displacement reaction, two ionic compounds exchange to form two new compounds.
Classify the following chemical reactions:
6. 2Mg(s) + O₂(g) → 2MgO(s)
7. CaCO₃(s) → CaO(s) + CO₂(g)
8. Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s)
9. HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
10. All redox reactions are also combustion reactions.
True
False
11. A precipitate is always formed in a double displacement reaction.
True
False
Match the reaction type with its general form.
