Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed

in lewis structure, a solid line is usually used to represent a bond between the atoms

Answer:
This has some interesting History in it.
Peat moss was once pounded into a sort of brick; sometimes with a little coal, these bricks were put to dry, and used for fuel.
The “Historical” part is in the name. I won’t go into why, ‘cause I type so slow and it is “extra”, but the peat, or coal, being TRULY organic, (that is made from plants) and burned as fuel is called “carbonixation”.
Explanation: Sort of a “Carbon + Oxidation”; many things in Chemistry have strange names that seem at first to make no sense; like “essence of Hartshorn”, is Ammonia (or ammonium hydroxide). A Hart is/was a type of deer in England and that area, and amines in the horn, when distilled, would yield Ammonia, “The Essence of Hartshorn”. Even the term “aromatic” has a long History, as do many compounds and nomenclature.
I hope that will do it.
