Question 1
Balance the following redox reaction if it occurs in basic solution. What are the coefficients in front of Al
and F
2 in the balanced reaction?
Al(
s) + F
2(
g) → Al
3+(
aq) + F
-(
aq)
◦ Al = 2, F
2 = 1
◦ Al = 3, F
2 = 2
◦ Al = 1, F
2 = 1
◦ Al = 2, F
2 = 6
◦ Al = 2, F
2 = 3
Question 2
What are the required coefficients to properly balance the following chemical reaction?
H
2(
g) + Cl
2(
g) → HCl(
g)
◦ 1, 2, 1
◦ 2, 2,

◦ 1, 1, 2
◦ 2, 1, 2
◦ 1, 1, 1
