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
