Maybe that substance can be an alloy.

I think your referring to an element, the basic unit(s) that cannot be broken down without fission.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
chemical compound can be broken down into simplier elements.
This is the atom, unbreakable by chemical methods.

A chemical element, or an element, is a material which cannot be broken down further or changed into another substance by using chemical means.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
yes, they can only be broken down by chemical means
glucose is broken down by cellular respiration

When the material of a potato is broken down in the small intestine, it is eventually broken down into glucose. The subsets are starch, maltose, maltase, and finally glucose.
any chemical compound broken down due to light energy.
