is that for the one where you had to say what the functional group was of T and S was?

Yeah it was the one which talked about distilling and other one requiring reflux and h2so4

One of em was aldehyde other was carboxylic acid

For everyone clarifying over the mGo Q :

White ppt will work as in chemistry as ppt is also referred to a solid and mgo is a solid

I don't think white flame will be correct as that's when you react it with oxygen not h2o which is steam and the flame stuff is Chem 5 which we is not meant to be tested in Chem 2

Everyone seems to be very wrong about the magnesium observations.

It should have been brilliant white flame/flash & white smoke, this is basic chem2 knowledge also required for chem5.

As for the paper it was pretty standard

I definitely got that propagation step, but I can't remember for the life of me if I put that termination....I hope I did :frown:

Oh crap we had to write CHCl2CHCl2!

I found that paper pretty disgusting tbh, I think I lost around 20-25 marks, is that around a B?

I think I lost that much too but found it nice, ffs.

I made loads of silly mistakes too, hopefully I can pull off a B and redeem myself in Chem 4 and 5 because my Chem 1 retake went pretty well!

It wouldn't be white flame if it was water. But it was steam. Perhaps flash may be a better word but aqa will not credit this squeaky pop **** everyone is talking about

What did everyone write for the question that wanted to know why Titanium can't be extracted with Carbon?

Titanium Carbide would be formed.

The magnesium reacting with steam (H2O) is a standard reaction, but observations haven't been asked for before. I think I got the white flame, but a precipitate surely wouldn't form, because there's no solution... I just went with increase in temperature as the other, but I doubt they'd allow that as an observation...they usually want formations or colour observations, but I couldn't think of anything else.
