⬇️Here is your answer ⬇️

The compounds formed when methane burnt in sufficient air are-
Carbon dioxide and water.

CH4 + 2O2 ------> CO2 + 2H2O

The compounds formed when methane burnt in insufficient air are-
Carbon monoxide and water.

2CH4 + 3O2 --------> 2CO + 4H2O

HELLO JUNUUU........!!!!!
GOOD AFTERNOON .........!!!!!!
HERE IS A DETAILED ANSWER........!!!!!!

==================================

❄❄❄❄ METHANE ❄❄❄❄

➡ Methane is the simplest hydrocarbon.

➡ Its molecular formula is CH4, i.e., it contains one atom of carbon linked separately with foyr atoms of hydrogen as shown in the first picture given above.

➡ It is the main constituent of the natural gas that is found along with petroleum.

➡ Natural gas contains 80-98 percent methane.

==================================

❄❄❄❄ REACTIONS ❄❄❄❄

[A]

✌✌✌IN SUFFICIENT AIR ✌✌✌

✔ When methane burns in sufficient air, carbon dioxide and water vapour is formed along with the liberation of large amount of heat.

✔ BALANCED REACTION : CH4 + 2O2
-----> CO2 + 2 H2O

==================================

[B]

✌✌✌ IN INSUFFICIENT AIR ✌✌✌

✔ When methane burns in an insufficient supply of air (oxygen), it forms carbon monoxide and water vapour (i.e., water)

✔ BALANCED REACTION :

(1) 2CH4 + 3O2 -----> 2CO + 4H2O

(2) CH4 + O2 -------> C + 2H2O

[When oxygen is very much low then C and H2O formation are observed]
