1000m³ of Carbon dioxide is required.
Propane is a type of hydrocarbon that is made up of a single carbon-carbon bond.
Propane burns in oxygen completely in a combustion reaction to produce carbondioxide and water.
The balance equation of combustion of propane gas is:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(g).
But noncombustibility of propane is the incomplete combustion of propane which occurs in absence or insufficient oxygen supply.
The balanced equation for noncombustibility of propane is:
2C3H8 + 9O2 → 4CO2 + 2CO + 8H2O
2 moles of propane = 4 moles of CO2
CO21 mole of propane = 2 moles of CO2 (4moles/2moles)
Therefore 500cm³ of propane = 2 × 500
= 1000cm³
Therefore, 1000m³ of Carbon dioxide is required to ensure the noncombustibility of a 500-cubic-meter compartment filled with propane vapor
