The mass of carbon per kg of flue gas is given by
Answer: Option
Explanation:
The mass of carbon, contained in 1 kg of flue or exhaust gases, may be calculated from the mass of carbon dioxide and carbon monoxide present in them.
We know that 1 kg of carbon produces 11/3 kg of carbon dioxide. Hence 1 kg of carbon dioxide will contain 3/11 kg of carbon. Also, 1 kg of carbon produces 7/3 kg of carbon monoxide, hence 1 kg of carbon monoxide will contain 3/7 kg of carbon.
Mass of carbon per kg of flue gas is given by:
3/11 CO2 + 3/7 CO.

Mass of carbon = 12 Mass of O2 = 32.
CO2(12+32) =44 + CO (12+16) = 28.
Mass of carbon present
44/12 CO2 + 28/12 CO.
11/3 CO2 + 7/3 CO.
CO2(12+32) =44 + CO (12+16) = 28.
Mass of carbon present
44/12 CO2 + 28/12 CO.
11/3 CO2 + 7/3 CO.

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.
Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.
