They give you 1 mark for writing the balanced chemical equation basically and 2 marks if you did something correct in the working out, so basically if you just make a calculation mistake i would say you might get 2 or 3, but most likely 3/4.

what was the balanced chemical eqn u were supposed to write

Im pretty sure it was BrCH2COOH (reversible arrow) --> BrCH2COO^- + H^+ and all are aqueous and then just write the Ka equation

How many marks lost if I put 0.53 for the last question instead of 0.39? Last question is out of 4

Boy your answer might be right lol. GPT saying its 0.53.

How harshly penalised would I be for the 7 marker about XYZ, if I didn't calculate the moles of each and use the molar mass? - Got order right and used all the other data kinda just forgot about the mass rip

Maybe two marks lost because it was just a simple c = n/V question, there was nothing much to do except for Z u had to use a mol ratio. Btw the order was Y, X, Z right or am i tripping

Yep - hopefully its just two, I think my explanation for everything else was solid

 

[askit]

What do you reckon you guys got raw?

 

[Steve 340]

depends on how much I lose for the last Q.

Hopefully 98

Damn nice, gunning for sr? I'm hoping for 92+ depending on how they mark the 7 marker and my writing

I mean it doesnt say to calculate the moles. or did it? and it also didnt say to use all the information provided.

guys i think i only got a 99 raw i coloured the wrong circle on q17 but had the right answer in my head. idk how i did this badly am i cooked?

 

[Steve 340]

Nah not sr, my school isn't great at sciences and people would have gotten the last question right.

Hopefully they mark leniently but they would want you to use all the given data imo

Nah you had to match titre volume using the concentrations they provided. I think.

 

[appleali]

mcq was not too bad right?

i calced molar mass instead

 

[ManifestationIsKey]

i calced molar mass instead

I mean thats fine as well. Either way you get the identity of the required species.

 

[Ishi081]

does anybody have the solutions to the questions?

 

[ManifestationIsKey]

Like for titre volume if you match it (you have to use a mol ratio for Z btw) you get that Y and Z have the same titre volume. But since Z is symmetrical it is the third 1.

yeh that was fine
