For carbon 0.80 x 100 = 80 grams of carbon; and for hydrogen 0.20 x 100 = 20 grams of hydrogen
80 grams carbon and 20 grams hydrogen.
The atmosphere.

Charcoal is an impure form of carbon, created from a variety of things, there is no definite formula for charcoal EDIT:(acslayder15) actually charcoal is a compound, it is made up of different types of elements anyway the chemical formula is C7H4O (mostly carbon, with some hydrogen and oxygen)
Carbon and hydrogen atoms
Carbon is a non meta element. Atomic mass of it is 12.
They are each an element A hydro-carbon is a compound
A carbon is an element, while a hyrdocarbon is a compound that has carbon and hydrogen in it.
Carbon
Butane is a compound that contains carbon and hydrogen atoms.
Methane is not an element. It is a compound of two elements: carbon and hydrogen.
They are each an element A hydro-carbon is a compound
The elements in this compound are: carbon hydrogen oxygen
Water, which is a compound of hydrogen and oxygen.
None. If carbon, hydrogen, and oxygen happen to chemically combine, they form an organic compound. 'Compound', not element. (These 3 substances are each an element).
Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.
Sugar is a compound of carbon, hydrogen and oxygen. C12H22O11.
methane is a compound as one carbon atoms combines with 4 hydrogen atoms.
