For the question about how to reduce heat loss, I put add a lid so that less heat is lost to the surroundings. Is that right??

Also, I think to get an A* you would need 45.

Wasn't the first question about neon not boron?

The atom described in the question about incorrect structure was referring to Neon and I think in the question the electron count was of Flourine??

Or am I wrong?

No you are right it was about neon not boron

Yh thats right

I think you have to be specific so it would be:

Aluminium oxide catalyst
400 to 700 degrees celsius

First boron (drawing the electronic structure), second was neon (what's wrong).

From this mark scheme, I got 52 i think. Is that likely to be an A*?

Also, on the Coursework, I got 40/50. If I get A* on each of C1,2 and 3, how likely am I to get an A* overall?

Thanks

No it would be around 52 because last year it was 50 for A*

What was the third question asking?

Was it not asking about sub-atomic particles and their charges in just the nucleus so you're not supposed to talk about electrons, right?

From this mark scheme i got roughly 47, what grade is that likely to be?

i think 35-38ish is an A sooo dont know.

AAAAH. This is insane; judging by the unofficial mark scheme I got around 58/60!

We had to draw the electronic structure? Damn I could have sworn I checked if I needed to draw anything on the first double page spread. Uh.

For the question on cracking I put 1. Very hot and 2. Catalyst is this too vague for even 1 mark ?

I really mucked up today and went into a state of total panic (I have severe anxiety). So annoyed at myself for making silly mistakes because I know that I knew the content and if I'm being honest, though I mucked up, it was a very good paper. If I mark myself harshly what do you think 40 - 45 would get me?

I put "high temperature" and "presence of a catalyst", not sure how many marks that would get though.

Realising you missed the first question out is quite a sickly feeling

I'm not entirely sure because some mark schemes say you have to write:

Aluminium oxides catalyst
400 to 700 degrees temperature

But others say that just stating catalyst and high temperature is enough.

I think you should definitely get at least one mark however.
