1. What does cracking do? 2. What are alkenes used for? 3. What are the two methods of cracking called?

Explanation:

1.)

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors.

2.)

They are used as starting materials in the syntheses of alcohols, plastics, laquers, detergents, and fuels. The most important alkenes for the chemical industry are ethene, propene and 1,3-butadiene.

3.)

Types of Cracking - Thermal Cracking and Catalytic Cracking. Cracking is a process by which complex high molecular weight organic compounds are broken down into smaller fragments of molecules.

is there any options? maybe im just not seeing them but i need the options to

here are some of the ways in which chemical and nuclear reactions differ.
