Right answer is 11/3 CO2 and 7/3 CO.

Imran Ali said: (Nov 14, 2014)  
A is right answer the mass of carbon per kg of dry flue gas is given by 11/3 CO2 and 3/7 CO.

Siva Bharath said: (Jul 3, 2015)  
I didn't get the answer. Please if you know well then explain.

Grandhi Sandeep said: (Aug 2, 2015)  
Some amendments need to be done for the options.

Kaushal said: (Jan 30, 2016)  
What is flue gas?

Sandeep Das said: (May 6, 2016)  
Can anyone explain the solution?

Biren Desai said: (Jul 8, 2016)  
Answer is wrong right answer is 3/11 co2 and 3/7 Co.

Rayudu said: (Jul 14, 2016)  
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.

Daka Hitesh said: (Aug 23, 2016)  
The right answer is 3/11 CO2 and 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.

Biplab said: (Dec 28, 2016)  
CO2 + CO = C.

C = 12, O2 = 32, O = 16,
CO2 = 32 + 12 = 44,
CO = 12 + 16 = 28,
CO2 + CO = C,
44 kg + 28 kg =12 kg,
44/12 kg + 28/12 =1 kg carbon,
11/3 kg + 7/3 kg = 1 kg carbon.

We know that one kg of carbon produced 11/3 kg of CO2 and 7/3 kg of CO.

So per kg of this gaseous, carbon will be produced 3/11 kg of CO2 and 3/7 kg of CO.

So, according to me, no any answer is correct in above mention option.

Anurup said: (Jun 15, 2017)  
It think 3/11CO2 + 3/7CO.

Chahat Sharma said: (Jun 17, 2017)  
Yes, you are correct @Sarfaraz.

Mehul said: (Dec 4, 2017)  
Right answer is 3/11CO2 + 3/7CO.

J.T.R said: (Dec 9, 2017)  
No, the correct answer is 3/11 co2+ 3/7 co.

@Biplab.

CO2 + CO = C is not balanced.
I think Balanced equation is CO2+2CO=3C+2O2.

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:
3/11CO2 + 3/7CO.

Tejaa said: (Oct 21, 2018)  
Yes, right @Syed Sameer.

Kapil said: (Aug 12, 2019)  
I think the answer would be 3/11CO2 + 3/7CO.

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.
