Propane, C3H8, in a tank that is usually the size of a basketball is often used for grills.
a) Write a balanced equation for the combustion of propane.
b) Calculate the number of moles of oxygen required to burn 5000.0 g (11.0 lbs) of propane.
c) Calculate the number of kilograms of O2 required to burn propane.
Use the general equation for balancing combustion reaction of hydrocarbons:
(a) CxHy + (x+ y/4)O2 → xCO2 + y/2H2O
In propane, x = 3, y = 8
x + y/4 = 3 + 8/4 = 5
y/2 = 8/2 = 4
Balanced equation ...
The solution writes a balanced questions for the combustion of hydrocarbons, number of moles and calculations of mass.
