"WHY!?"

Can someone tell me why Flakes(chocolate bar) don't melt and just end up burning.

I know they melt eventually if you leave them out,but I want to know why they burn if you heat them up.

WHY?! WHYYYYYY!?

Combustion is combustion, exposed to a flame or not. It may not give a flame as it burns, bit it will form an oxide of some sort if it's burning.

You need to differentiate between inTRAmolecular forces, and inTERmolecular forces, before you start talking about IMF's

i cant believe this has got 54 replies!

yes but the less imfs there are the quicker the atoms are separated, therefore ...

hang on a minute what do you mean it burns? Do you get a flame? are you exposing it to a naked flame? mystique I neeeeeeed answers.

You havent explained yourself properly

Intermolecular forces are related to bonding between molecules. This will affect the melting point. Not so much whether it burns though.

Intramolecular forces are the forces holding the indivisual atoms together in the molecule. If something combusts, they need to be broken so that an oxide can be formed. It is they that will be more relevant to cumbustion.

oh well venom I want to prove that it is imf's at work, you want to use exothermic reactions. we'll se who's right 2morrow!

Nooooo! You'll all see how horribly wrong I am!

if she's in a good mood she'll probably let us experiment ourselves!!!

yeah,actually make the teacher work instead of drinking coffee all day

tell you what mystique I'll ask my chemisrty teacher tomorrow, and see if she knows why!

CD

My Chemistry teacher would be so proud.

Either that, or she'd tell me my answer was horrendous. That used to happen a lot actually.
