Heat and Alkenes
Cracking long-chained hydrocarbons produces two things which include alkenes and alkanes(shorter chains), including hydrogen through catalytic cracking.
a catalyst and high pressure
It loses two hydrocarbons and creates a double bond (between the carbons).
These hydrocarbons are ethane, propane, butane.
Cyclic hydrocarbons are organic compounds made of carbon and hydrogen. They are structured in rings, or circles. Two examples are cyclobutane and cyclopropane.

What two hydrocarbons are used to make plastic
Hydrocarbons are aliphatic and aromatics.
It loses two hydrocarbons and creates a double bond (between the carbons).
It is a crack in time and space, created by the Doctors TARDIS exploding. The crack appears in many places, and removes things from time itself. It can also act as a wormwhole between two places.
Glucose and oxygen
These hydrocarbons are ethane, propane, butane.
Two eggs and Two Sperm.
Hydrogen and carbon.
They needed a keep because that was the strongest part of the castle and the portculis.
