Answer:
The balanced chemical reaction of combustion of methane is:
734 liters of carbon dioxide gas is produced. .
Explanation:
The balanced chemical reaction of combustion of methane is:
Mass of methane gas = 0.500 kg = 500 g (1 kg= 1000 g)
Moles of methane =
According to reaction, 1 mole of methane gas gives 1 mole of carbon dioxide gas. Then 31.25 moles of methane will give :
of carbon dioxide
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas =
V = Volume of gas =?
n = number of moles of carbon dioxide gas = 31.25 mol
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of gas =13.0°C=13.0+273.15 K= 286.15 K
Putting values in above equation, we get:
V = 734.15 L ≈ 734 L
734 liters of carbon dioxide gas is produced. .
