AQA GCSE Chemistry Paper 2 Higher Tier (8462 2H) - 13th June 2023 [Exam Chat]

yes bro, i got the same. idk what the real answer is.

im pretty sure its 7. something because i got 4 originally then changed it. U had to work out how much anhydrous there was, which was 23 i think, then divide by some ratio to get 7. Idk if this makes sense but yh

what do u need to make nitric acid? i said nitrogen dioxide but that was a complete guess cut i had no clue

Following the same method for the question above , I used a ratio and worked out a multiplier , getting something along the lines of 7.4 / 7.2

Do you guys think the grade boundaries for chemistry this year will stay the same as the 2019 boundaries? Or do you reckon there may be a small drop, perhaps by 1 or 2 marks?

If it changes it most certainly will not be a drop. I have said this already early but grade boundaries are based on percentages of people getting a grade, not the actual mark. So if we all do better (which i looks like we did) the grade boundaries move up to counteract that. If we did worse than usual, the grade boundaries move down to ensure the same amount of people get each grade as usual (or pretty much)

remember the people on studentroom will usually do a lot better than the average population

True but it doesn't change the fact that those papers were easier than usual. Even people who usually struggle are doing much better year. Your right that it wont increase as much as people on tsr are saying but it will still increase

Isnt it calcium carbonate- i put calcium carbonate initially but changed it last second, ahhh the regret-

I put nitrate

Provides an alternative reaction pathway with lower activation energy so greater chance of successful collisions

yh i agree but grade 9 is probably not gonna above 75 percent

Was one answer cellulose for the Q abt glucose

Nah it’s calcium hydroxide

I don’t actually remember what I said but wow such a good answer
