# OCR Chemistry Salters B F331 27th May 2016 (Old specification) Watch

I know for sure I lost 11 marks. I just hope I don't lose anymore because of the mark scheme being so specific, I just wanna scrape an A

Dont look at this paper as trying to get an specific grade, look at it as marks. So just say you dropped 2 marks on a calculation and tell yourself that "it could be the difference between a B and an A", it will only be a 4ums drop that split over the 4 papers is 1 ums dropped per paper. Another view point is that in order to achieve an A you need 480 ums, so dropping 4
ums is exactly 0.83 % of the marks you will need, that can be made up easily across the remaining 390 ums! Stay postive

How do you people revise for A2?

Feeling ready for F334 and F335?

I use the Thin OCR Heinmann revision guide ( the greenish black front page) and the CGP book.

I do all the past papers too.

What do you guys do exactly and how are you feeling?
I've made flashcards and I do past papers.

3. Can someone show the answer and equation for energy density with the numbers put in the equation
4. What did people put for why carbon and sulfur (I think it was) would be on the right hand side of the periodic table?

Dont forget the 120 ums from coursework! Lol just focus on trying to get the bulk of the marks. Besides if ur going for an A* you can even get mid Bs at AS.
6. Don't know how I felt about that paper. Some parts were good tho. I got the 36200 for the energy density I think. The calculation parts messed me up

Sad bit is that my method waa right by i came out with 29%... Method marks shud give me 1/2 marks so not too bad . (Realised just now writing the calculation out)
Actually there could be a range, if u round to 2 dp your answer comes to 29% defo method marks however

That's carbonates?

Nah pal, milk of magnesia (Mg(OH)2) is a white suspension,solubility of group 2 carbonates decreases down the group.

I said because its electron configuraton outer shell is the p shell? so its a p block element? not entirely sure if thats what they were looking for

Yeah....I didn't get that question. I just put particulates lol 😂

Posted from TSR Mobile
Lol i put particulates but apparently was meant to be photochemical smog
15. I wrote particulates 😂

frequency ------->
because the lines converged towards the right, i.e at the higher frequencies
But it was for the graph wasn't it and so it'd be frequency <---- and wavelength --->

The Uranian decays to Thorium? Is this right
That's what I got
18. (Original post by KINGYusuf)
I wrote for similarity the position of the lines are in the same position for both? Is that right

Posted from TSR Mobile
Yeah that's what I put and it's what has been accepted in mark schemes before so should be fine

They're covalent compounds and covalently bonded compounds are located on the right of the periodic table

I put that too. Hopefully its correct!

Ahahha yeah hopefully, I don't see why it wouldn't. If I remember it did say to use the table and even if it didn't, it makes sense to use the data in the table in the answer else why would they give it to you
