Explain in terms of types of matter why methane can be broken down by chemical means but argon cannot?

Methane is a hydrocarbon or an alkane. It is made up of two different elements : carbon and hydrogen. It has one carbon atom and four hydrogen atoms. Methane is CH₄.

Argon, Ar is an element. It is also known as an inert gas. Element is a fundamental chemical unit and it cannot be further broken down.

A molecule on the other such as methane is made up carbon and hydrogen. Methane can be further broken down into its elemental form.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
