Read each question carefully and provide the best answer. Good luck!
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 single displacement reaction, a more reactive element displaces a less reactive element from its compound. Which of the following metals would displace hydrogen from hydrochloric acid (HCl)?
Copper (Cu)
Silver (Ag)
Zinc (Zn)
Gold (Au)
3. A chemical reaction in which a compound breaks down into two or more simpler substances is called a reaction.
4. The products of a complete combustion reaction of a hydrocarbon are always and .
5. In a double displacement reaction, two elements swap places in a compound.
True
False
6. A reaction between an acid and a base is a type of double displacement reaction.
True
False
7. Balance the following chemical equation and identify the type of reaction:
Fe + O₂ → Fe₂O₃
8. Describe the key characteristics of a combustion reaction.
Match each chemical equation with its corresponding reaction type.
9. 2H₂O → 2H₂ + O₂
a. Synthesis
10. AgNO₃ + NaCl → AgCl + NaNO₃
b. Decomposition
11. CH₄ + 2O₂ → CO₂ + 2H₂O
c. Single Displacement
12. 2Na + Cl₂ → 2NaCl
d. Double Displacement
13. Zn + CuSO₄ → ZnSO₄ + Cu
e. Combustion
