Read each question carefully and provide the best answer. For reaction questions, predict the products and balance the equation.
1. In a single replacement reaction, a more reactive element replaces a less reactive element in a compound. Which of the following is an example of a single replacement reaction?
2Na + Cl₂ → 2NaCl
HCl + NaOH → NaCl + H₂O
Mg + 2HCl → MgCl₂ + H₂
CO₂ + H₂O → H₂CO₃
2. A double replacement reaction typically involves the exchange of ions between two compounds in aqueous solution. Which of the following is a characteristic product of many double replacement reactions?
A single element
Heat and light
A precipitate, gas, or water
Two new elements
3. In a single replacement reaction, a more element displaces a less reactive element from a compound.
4. A double replacement reaction occurs when the of two ionic compounds exchange places.
5. Predict the products of the following single replacement reaction and balance the equation:
Zn(s) + CuSO₄(aq) →
6. Predict the products of the following double replacement reaction and balance the equation:
AgNO₃(aq) + NaCl(aq) →
