Answer 1

Correct Answer - Option 1 : D

The Correct Answer is "D".

• When methane burns, CH4 + 2O2 → CO2 + 2H2O.
• When methane burns in presence of air or oxygen, it produces a large amount of heat, along with carbon dioxide and water vapour formation. 

 

• Methane is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen).
• It is a group-14 hydride and the simplest alkane and is the main constituent of natural gas.
• The largest reservoir of methane is under the seafloor in the form of methane clathrates.
• When methane reaches the surface and the atmosphere, it is known as atmospheric methane.
