Question

what is the chemical reaction here⇒ a person farting.

Answer 1

Chemical Makeup of the Average Fart. 59% nitrogen, 21% hydrogen, 9% carbon dioxide, 7% methane and 4% oxygen—all essentially odorless. (Less than 1% is what makes farts stink.)

Answer 2

This reaction is inside our body.

Though farting is a big sonorous phenomenon for you,you can say that if you are going to construct a pipeline,then after some days your fart will be the bio gas.

Reaction is simple.We ear organic substances,they will be changed into methane,carbon dioxide by bacteria's.Reaction is complex now.
