which of the following green house gases is a contributor due to incomplete combustion of coal and petroleum? 1=Oxides of nitrogen. 2=Methane. 3=Carbon monoxide. 4=Carbon dioxide.
Answers
Answer:
3. carbon monoxide
Explanation:
Carbon monoxide is produced by incomplete combustion of coal and petroleum.
3 = Carbon Monoxide, a green house gas is the contributor due to incomplete combustion of coal and petroleum.
Combustion is nothing but the process of burning in the presence of oxygen.
Similarly, incomplete combustion would mean burning in the absence or very low concentration of oxygen.
When coal (C) undergoes incomplete combustion, i.e. burns in the presence of very low oxygen gas, a very poisonous gas, Carbon monoxide (CO) is produced which is very much lethal.
The reaction happening is shown below:
2C (coal) + O₂ (low conc.) → 2CO (Carbon monoxide)
CO on mixing with haemoglobin of blood forms a stable compound known as carboxylhaemoglobin which cuts off the regular oxygen flow in our body (reduces our blood's ability to carry oxygen) thereby leading to death.
