Question

One variety of household fuel is a mixture of propane (60%) and butane (40%). If 20 litres of this mixture is burnt, find the total volume of carbon dioxide added to the atmosphere. The combination reactions can be represented as:

\[\ce{C3H8 + 5O2 -> 3CO2 + 4H2O}\]

\[\ce{2C4H10 +13O2 -> 8CO2 + 10H2O}\]

Answer 1

Mixture contains 12 lit of propane and 8 lit of butane

Carbon dioxide released by propane is 36 lit

Carbon dioxide released by butane is 32 lit

Total volume of carbon dioxide added to the atmosphere is 68 lit.
