Question

Balanced equation for burning of methane gas and equation for decomposition of vegetables matter into compost

Answer 1

The combustion of methane or the balanced equation for methane gas is as follows;

CH4 (methane) + 2O2 (oxygen in molecular form and in particular excess presence in the environment itself) 》CO2 (Carbon dioxide in elementary form, compound) + 2H2O (water molecules)

The bond formation in methane and oxygen are separated out of it and they are subsequently rearranged with another bonding and the other two water molecules are generally released as steam or water vapour during the whole reaction and energy formation. Since, the combustibles of methane will usually depend upon the availability and abundance of the oxygen then only it can create a perfect complete combustion otherwise incomplete combustion are bounded to happen. This is making two components called water molecules and carbon dioxide respectively.

The second part of the question is about the equation for decomposition of vegetables matter into a compost. The decomposition of the vegetable matter into a useful compost (for plantation), which is primarily carried out by the microorganisms and microbes present in the soil or artificially given through means of a medium, this involves the total breakdown of organic compounds and breakdown of different types of bonds which are found in great abundance and will heavily depend upon the type of vegetable given, as, there are regularly changing chemicals for organic compounds because product of it will be formed depending upon the chemical reactions of each and every organic compound. Compost reactions occur through multiple enzymatic reactions which also involves a variety of organisms and oxidative components as well as numerous intermediate compounds.
One specific reaction which would undergo in some vegetables with a exothermic reaction.

HC2H3O2 (acetic acid)+ 4H2 (hydrogen in gaseous form) + CO2 (carbon dioxide in gaseous form) 》2CH4 (Methane in gaseous form) + 2H2O (water in liquid form) + CO2 (carbon dioxide in gaseous form).
This reaction happens almost in every vegetable or fruit undergoing a compost reaction through microbes.
