Oxygen is organic, the others at the instant are not. Now you tell me why? a. mix of rock and stuff b. water (H2O) hydrogen and oxygen c. oxygen (O) gaseuous ingredient from periodic table d. air mix of gases that incorporates oxygen, hydrogen, nitrogen, carbon dioxide and different property you probably did no longer think of i became going to grant you the respond without you learning something did you?

Heterogenous mix
Sand is a term for soil particle size, less than gravel but larger than silt (which is larger, in turn, than clay).

Could be either one. There are places of natural occuring extremly pure quartz sand, SiO2.

It is pure substance in that it consists of nothing non-substantial.
