## Practice Problems

Now that you can find the limiting reagent, lets do some practice problems

*NOTE FOR ALL PROBLEMS USING Chlorine THE ATOMIC NUMBER IS 35.45, DO NOT ROUND*
For all others, round up or down depending on the chemical
*When doing these problems I used a scientific calculator, and I did not round at ALL till the end, because of how the input boxes work, only one answer is correct. I supplied the correct ending to the problems next to the questions*

1) For the balanced equation shown below, if 55.5 grams of C2H6S were reacted with 281 grams of O2, how many grams of CO2 would be produced? Answer ends in .7

C2H6S+5O2 Yields 2CO2+3H2O+SO3

2) For the balanced equation shown below, if 53.4 grams of CBr4 were reacted with 3.21 grams of O2, how many grams of CO2 would be produced? Answer ends in .4

CBr4+ O2 Yields CO2+2Br2

3) For the balanced equation shown below, if 21.2 grams of C6H5Cl were reacted with 30.3 grams of O2, how many grams of CO2 would be produced? Answer ends in .7

C6H5Cl+7O2 Yields 6CO2+2H2O+HCl

4) For the balanced equation shown below, if 30.3 grams of CaCN2 were reacted with 15.6 grams of H2O, how many grams of CaCO3 would be produced? Answer ends in .9

CaCN2+3H2O Yields CaCO3+2NH3

5) For the balanced equation shown below, if 12.0 grams of Fe were reacted with 100 grams of FeCl3, how many grams of FeCl2 would be produced? Answer ends in .5

Fe+2FeCl3 Yields 3FeCl2

6) For the balanced equation shown below, if 8.97 grams of C3H6O2 were reacted with 7.68 grams of O2, how many grams of H2O would be produced? Answer ends in .7

2C3H6O2+7O2 Yields 3CO2+6H2O

7) For the balanced equation shown below, if 8.70 grams of Cu were reacted with 1.29 grams of S, how many grams of Cu2S would be produced? Answer ends in .45

2Cu+S Yields Cu2S
