Homework 1

Balance the following equations:

1) ___ N2 + ___ F2  ___ NF3

2) ___ C6H10 + ___ O2  ___ CO2 + ___ H2O

3) ___ HBr + ___ KHCO3  ___ H2O + ___ KBr + ___ CO2

4) ___ GaBr3 + ___ Na2SO3  ___ Ga2(SO3)3 + ___ NaBr

5) ___ SnO + ___ NF3  ___ SnF2 + ___ N2O3

Using the equation from problem 2 above, answer the following questions:

6) If I do this reaction with 35 grams of C6H10 and 45 grams of oxygen, how many grams of carbon dioxide will be formed?


7) What is the limiting reagent for problem 6? ___________

8) How much of the excess reagent is left over after the reaction from problem 6 is finished?


9) If 35 grams of carbon dioxide are actually formed from the reaction in problem 6, what is the percent yield of this reaction?
