Answer 1

Answer #1

1)

balanced equation :

2 C2H2 (g) + 5 O2 (g) --------> 4 CO2 (g) + 2 H2O (g)

2 mol acetylene --------> 4 mol CO2

?? C2H2 ------------> 0.055 mol Co2

moles of acetylene = 0.055 x 2 / 4

= 0.0275 mol

moles of acetylene = 0.028 mol

2)

6 CO2 (g) + 6 H2O (l) --------------> C6H12O6 (s) + 6 O2 (g)

1 mol glucose ---------> 6 mol CO2

1.6 mol glucose ------> ??

moles of CO2 needed = 1.6 x 6

moles of CO2 = 9.6 mol

Acetylene gas produced in the experiment in question #2 is the gas used in welding torches. Recall its formula is two carbons and two hydrogens. You could take the balloon full of acetylene from question #2 and tie it to the end of a meter stick. Then if you hold the balloon near a burner flame, the balloon will explode as the oxygen from the air (O2) combines with the acetylene (two carbons and two hydrogens). The exothermic reaction produces...
