Answer Key
If you get less than 5/5 correct go to More Practice Problems.
If your errors were due to incorrectly calculating the Molar Masses, go to "Practice with Molar Masses."
If your errors were due to incorrectly rearranging the equation, go to "How to Find the Limiting Reagent."
1) H2 is the Limiting Reagent.
1 = 16.8
1 26.3
16.8 (H2) = 26.3 (Cl2)
2) O2 is the Limiting Reagent
2 = .935
3 1.01
2.805 (C2H3O2Cl) = 2.02 (O2)
3) O2 is the Limiting Reagent
1 = .3636 1.71
1.71 (O2) = 2.178 (C3H6S)
4) O2 is the Limiting Reagent
2 = .009
1 .003
.009 (NO) = .006 (O2)
5) HCl is the Limiting Reagent
2 = 1.98
6 = 3.80
11.88 (Al) = 7.6 (HCl)
