Homework Answers

Answer #1

1)

2 C2H6 + 7 O2 ----------------------> 4 CO2 + 6 H2O

   2 mol       7 mol                               4 mol     

                                                           2.8 mol

4 mol of CO2 produce from --------------- 7 mol of O2

2.8 mol of CO2                      ------------- x mol of O2

moles of O2 = x = 2.8 x 7 / 4

                   = 4.9 mol

moles of O2 = 4.9 moles

2)

CO2 + 4 H2   ---------------------> CH4   + 2 H2O

1 mol                                             1 mol

1 mol CO2 -----------   1 mol CH4

36.6 mol CO2 --------- 36.6 mol CH4

moles of methane = 36.6 moles

3)

CO2     +    H2 ----------------->   H2O + CO

       1 mol                         1 mol

                                                   53.6 mol

1 mol H2 gives --------------- 1 mol H2O

53.6 mol H2 --------------- 53.6 mol H2O

moles of H2 = 53.6

1)

balanced equation :

6 CO2 + 6 H2O   ----------------------> C6H12O6 + 6 O2

2) Determine how many moles of CO2 are required to produce 42.0 mol of glucose.

6 CO2 + 6 H2O   ----------------------> C6H12O6 + 6 O2

6 mol                                                     1 mol

x mol                                                       42 mol

moles of CO2 needed = 42 x 6 / 1

                                     = 252 mol

3) How many grams of sulfur can be made in the following reaction if 17.0 grams of H2S reacted with excess SO2?

2 H2S   +   SO2 ---------------->    2 H2O   +   3 S

68 g                                                                   96 g

17 g                                                                    24 g

grams of sulfur needed = 24 g
