Cracking and alkenes

Pregunta	Respuesta
hydrocarbons can be cracked to produce what	smaller, more useful molecles
what methods are there of cracking	catalytic cracking and steam cracking
what is catalytic cracking	heavy oil is passed through metal chambers under pressure and high temperature in the presence of catalysts. This boiling breaks up long-chain oil molecules into simpler short-chain molecules.
what is steam cracking	Steam cracking is an uncatalyzed process, steam is added to long-chain hydrocarbons. This way lowers the force of the hydrocarbons so that condensation reactions are made lower.
what are the products of cracking	alkanes and alkenes
what do alkenes react with	bromine water, it turns from orange to clear when they are reacted together
what is there a high demand for in fuel	fuels with short chain molecules
what are alkenes used to produce	polymers (plastics)
why is cracking useful	because we depend on having lots of fuel with a high energy value and cracking will help provide us with that
