The chemical reaction for me, surely the sugar is reacting with the water as well?

10/13 - kicking myself for the ones I got wrong like, especially the Nitrogen one.

A chemical reaction produces chemical changes at the end of it. I.E. The rusting is oxidation of the metal - and you get an oxidised material at the end of it.

Dissolving sugar in water produces no reaction or new chemicals - it is just a solution of sugar in water - a physical, not chemical, change.

I see, but surely chemical reactions are physical reactions.

The sugar is just diffused in the water. It's still sugar. I think a chemical reaction has to involve a transfer of electrons & the formation of new chemicals.

Yes I get the solution isnt a reaction..I was just commenting that chemical reactions are actually physical..just on a molecular scale.

This is the correct answer - basically anything that changes the electron orbits (molecular bonds) of a substance. That's why freezing or boiling water is a physical change & and not a chemical change.

The worrying thing is that something like two thirds of the original voters scored even lower :)

Since the weather is has been absolutely gorgeous (20°C, clear blue skies, sunshine) down here in Londinium, fit female police officers should be made to walk around in skimpy sexy underwear. And it's against the law for them not to pose for photos.

Yes but...the moving of electrons is a physical thing is it not, as in everythings physical, unless there's some magical non physical thing going on.
