Methane is a colorless gas, and diamond is a hard solid. A methane molecule is made of one carbon atom surrounded by four hydrogen atoms. Diamond is an extended structure made of carbon atoms connected in a repeating pattern. Draw a model of a few methane molecules and a model of the extended structure in diamond. Use your model to explain whether methane and carbon are pure substances, such as compounds or elements, or are mixtures.

The molecules contain like 54 of water 

Compound with sulfer  is bright red
