In chemistry, there is a class of compounds called alkanes. they have the general formula c subscript x baseline h subscript 2 x 2, where c stands for a carbon atom and h stands for a hydrogen atom. the subscript x stands for the number of carbon atoms, and the subscript 2 x 2 stands for the number of hydrogen atoms in one molecule of the compound. carbon atoms hydrogen atoms alkane formula 1 4 c h subscript 4 2 6 c subscript 2 baseline h subscript 6 3 8 c subscript 3 baseline h subscript 8 suppose an alkane had 8 carbon atoms. how many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms
