Describe 4 differences between short chain hydrocarbons and long chain hydrocarbons and explain how this determines their uses Ill give brainliest

The term HYDROCARBONS means organic compounds which contain only carbon and hydrogen. By using this definition, four classes of hydrocarbons are included: alkanes, alkenes, alkynes and aromatic.

Hydrocarbons are organic compounds composed of only carbon and hydrogen. The alkanes are saturated hydrocarbons—that is, hydrocarbons that contain only single bonds. Alkenes contain one or more carbon-carbon double bonds.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
