What is the name given to the process of breaking up the molecules of hydrocarbons?
The process is called 'cracking' or more properly "Fluid Catalytic Cracking". It takes place in a Catalytic Cracker (cat cracker) where a combination of high heat, pressure, and chemical catalysts break long chain hydrocarbons into more valuable shorter chain ones. A catalyst is a compound that speeds up (or slows down) a reaction without being used in the reaction. So a catalyst can be used over and over again for the same process.
What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
What is a cracking of a oil fraction?
It is when you break large hydrocarbons/alkanes, into smaller more useful alkanes/alkenes. For example a large hydrocarbon in crude oil is Bitumen. By passing this substance over a hot catalyst, you can break it down into smaller hydrocarbons such as Petrol or Diesel
What causes thermal conductivity?
when heat travells through a material which over heats it. Thermal conduction then applies
How do you indicate that a catalyst was used in a reaction?
You write the name over the arrow in the chemical equation.
What are the advantages of thermal cracking over catalytic cracking?
Carbonium ion process
What are the advantages of catalytic cracking over thermal cracking?
Carbonium ion process
What are the advantages of hydro-electric power over thermal power?
a lot
What are the products of cracking decane?
Hexane when passed over a hot catalyst, produces Butane (an alkane) and Ethene (an alkene) Hexane --------> Butane + Ethene C6H14 ---------> C4H10 + C2H6
What is the black solid that is formed in the combustion of hexane?
Coke, most likely. Coke is the carbonaceous residue left over from the thermal "cracking" of hydrocarbons (the term is also used to describe the residue left over from coal combustion).

How do you use catalyst in a sentence for murder?
The catalyst for the murder was a heated argument over money.

Why enzymes can be used over and over?
Because they are catalyst and are regenerated / recovered.
What are asphalt's advantages over concrete?
Its physical properties also make it less susceptible to cracking and weathering; it is also more resistant to salts and chemicals used to clear and maintain roads in inclement weather.
