The equation shows the complete combustion of propane.
C3H8(g) + 5O2(g) --> 3CO2(g) + 4H2O(i)
Which statement is correct?
A) 10cm3 of propane cannot burn if less than 50cm3 of oxygen is present.
B) 10cm3 of propane would produce 40cm3 of liquid water.
C) 100cm3 of oxygen would be sufficient to react completely with 20cm3 of propane.
D) This reaction would result in an increase in the volume of gas.

  1. I would go with c. The a answer is a little misleading. 10 cc propane would require 50 cc oxygen TO BURN ALL OF THE PROPANE; HOWEVER, some propane will burn if some oxygen is present. If less than 50 cc not all of the propane will burn.
