## Practice Problems

Do you remeber how to find the limiting reagent??
We will see
So now, lets do some practice problems
Chlorine has an atomic weight of 35.45, DO NOT ROUND
For all others, round up or down depending on the chemical
1) For the balanced equation shown below, what would be the limiting reagent if 1.72 grams of C6H6S2 were reacted with 3.48 grams of O2?

2C6H6S2+19O2 Yields 12CO2+6H20+4SO2

So whats the limiting reagent
Compound 1 or Compound 2
2) For the balanced equation shown below, what would be the limiting reagent if 80.9 grams of NH3 were reacted with 108 grams of O2?

4NH3+5O2 Yields 4NO+ 6H2O

So whats the limiting reagent
Compound 1 or Compound 2
3) For the balanced equation shown below, what would be the limiting reagent if 17.0 grams of N2H4 were reacted with 62.3 grams of H2O2?

N2H4+2H2O2 Yields N2+ 4H2O

So whats the limiting reagent
Compound 1 or Compound 2
4) For the balanced equation shown below, what would be the limiting reagent if 84.6 grams of K2O were reacted with 21.0 grams of H2O?

K2O+H2O Yields 2KOH

So whats the limiting reagent
Compound 1 or Compound 2
5) For the balanced equation shown below, what would be the limiting reagent if 86.4 grams of KO2 were reacted with 16.3 grams of CO2?

4KO2+2CO2 Yields 2K2CO3+3O2

So whats the limiting reagent
Compound 1 or Compound 2
6) For the balanced equation shown below, what would be the limiting reagent if 31.2 grams of C4H8O2 were reacted with 74.2 grams of O2?

C4H802+5O2 Yields 4CO2+4H20

So whats the limiting reagent
Compound 1 or Compound 2
7) For the balanced equation shown below, what would be the limiting reagent if 83.0 grams of CH4 were reacted with 1040 grams of Cl2?

CH4+4Cl2 Yields 4HCl+CCl4

So whats the limiting reagent
Compound 1 or Compound 2
8) For the balanced equation shown below, what would be the limiting reagent if 43.8 grams of Al were reacted with 233 grams of Cr2O3?

2Al+Cr2O3 Yields Al2O3+2Cr

So whats the limiting reagent
Compound 1 or Compound 2
9) For the balanced equation shown below, what would be the limiting reagent if 69.2 grams of P were reacted with 345 grams of Br2?

2P+3Br2 Yields 2PBr3

So whats the limiting reagent
Compound 1 or Compound 2
10) For the balanced equation shown below, what would be the limiting reagent if 33.1 grams of NO were reacted with 27.2 grams of O2?

2NO+O2 Yields 2NO2

So whats the limiting reagent
Compound 1 or Compound 2
