My homework is questions on cracking hydrocarbons.

I think number 1 is hydrogen and carbon, but I cant do any others. Also, we didn't take any notes in class. Also, before any hate, fuck off. Any helpers greatly appreciated. If you can't help, leave.

NeatSquidYT: We'd need the beginning of the experiment to tell which hydrocarbon, but yes, Hydrogen and carbon.

The projects never end in my line of work.

 Im starting to get the feeling that you just offload all of your homework onto the forum :P

 Only the ones I can't do. Yahoo answers takes too long and the answers can be iffy. 

He's a mouthy little shit too ;)

Yep. Just how I am.

1. Carbon and oxygen 

2. Catalysts are temporarily involved in the reaction so the hydrocarbon attaches to the active site of the catalyst and thus the black colour. The word for when a molecule is attached to an active site too strongly is strong adsorbtion. Catalyst reactions involves three steps adsorption, reaction occuring on the active site and lastly the reaction product desorbing from the catalyst.

3. HC+ Oxygen = carbon dioxide and water (general combustion) 

4. Most likely changed boiling points as the hydrocarbon chain is shorter there are fewer molecules for van der walls forces to occur, it's the intermolecular forces that break not the carbon hydrogen bonds when it boils. 

7. Bromine water tests for double bonds, double bonds are called unsaturated because they don't have as many Hydrogens as a molecule with no single bond, the process that starts this is called addition reaction, it happens because there is a high concentration in the c=c bond, this induces a dipole in the Br-Br and makes it electronegative on one side, that induced dipole makes the br-br "break" and then the carbon structure is positive and the :Br- (it got electrons from the bromine when it split off) is attracted to the positive carbon due to it giving an electron to the bromine. The cracked gas.
