## 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
