Is an 'Enthalpy change' the same as the 'energy change'?]

Please, t'is urgent.

I know about rates of reaction graphs and activation energy and maxwell-boltzman curves and such like, which I am assuming is related.

"Enthalpy"?

Never heard of it.

Enthalpy is the energy content of a substance.
You're thinking of Enthalpy change, which is the difference of the enthalpy of the Products and Reactants.

Change in enthalpy = Product Enthalpy - Reactant Enthalpy.

Har-di-har...

Na, didn't work. The rest weren't too convinced either. He did get a day off though, despite it not being FA Cup final day.

It's probably to try and impress people and get a day off school. Enough said.

Most probs a lie. Back in Year 7, my friend said he won a competition to be a football mascot and get free Nike stuff at the FA Cup final, but obviously it was all a pack of lies.

There's a possibility if it's on Wednesday... But then again, I don't know the PMs plans for the week :-P

HHAT, i wonder if you can help me, one of my mates 'claims' he won an essay competetion, which none of us knew about, and that his prize is to meet the PM tomorrow, know anything about it, cus he really does suck at english, and 'we' were thinking he's probably made it up, because he feels neglected or something. Any info is appreciated...

I suck at science, so I can't really help here.
