A compound's name is generally based on the elements invoved. The process of naming them is taught in basic chemistry.
Organic compounds
These compounds are called alkanes.
down there in North Dakots is where you will find your answer
carbohydrates, proteins, lipids, and nucleic acids
Actually, yes!
It occurs in nature. All natural products considered organic.
S. H. Tucker has written: 'Separation and identification of organic coumpounds'
nonane and hexane are miscible as both are non polar
Because the proportions of the elements are different in the different compounds. They may contain the same elements, but the different proportions make them different compounds with different properties.
Yes, it is possible (although fairly unlikely). The B12 compound won't cause the swelling, but one or more of the inert coumpounds in the formulation could cause the facial swelling.
Halogens such as fluorine or chlorine are HIGHLY reactive; they always undergo chemical reactions with other elements to form compounds. It's almost impossible to find pure samples of any halogen gas.
The "Noble gases" of group VIII are unreactive, because they are stable, due to their electron arrangements. If an atom has a full outer shell, it is "happy" and will not bond with other atoms.
