Read each question carefully and provide your best answer. Some questions may require balancing chemical equations.
1. In a single displacement reaction, what type of element displaces another element from a compound?
A less reactive element
A more reactive element
An inert element
Any element
2. Which of the following is an example of a single displacement reaction?
HCl + NaOH → NaCl + H₂O
2Na + Cl₂ → 2NaCl
Zn + CuSO₄ → ZnSO₄ + Cu
