Question 1

Balance the following redox reaction if it occurs in acidic solution. What are the coefficients in front of Zn and H+ in the balanced reaction?

Zn2+(aq) + NH4+(aq) → Zn(s) + NO3⁻(aq)

◦ Zn = 3, H⁺ = 5
◦ Zn = 1, H⁺ = 8
◦ Zn = 1, H⁺ = 4
◦ Zn = 4, H⁺ = 10
◦ Zn = 2, H⁺ = 4

Question 2

How many electrons are transferred in the following reaction? (The reaction is unbalanced.)

Mg(s) + Al3+(aq) → Al(s) + Mg2+(aq)

◦ 4
◦ 6
◦ 2
◦ 3
◦ 1
