hi i just wanted to ask, aren't the concentrations calculated in 19bii wrong? like 0.02/(100/1000) simplifies to 0.02/0.1 which is 0.2. although it probably don't matter as the ratio of [HA]/[A-] will not change
OMDSSSS please do not rip out ur hair ,eat it, jump off a cliff and go to hospital. I promise I won’t be a brainless fricking blegh as u said , i need u alive for the 2017 paper 1 walkthrough too😰 . i literally barely ever comment but i genuinely THANK U SO MUCHHHH i think you’ve drilled it into my head now not to think only arrows as soon as u see those qs😭😭😭😭 i cant thank u enough
hello, on question 19 1:08:57 - I lost a mark because I didn't see where it says the original unit was in grams. how did you identify that it was in grams
@@the-a-level-cookbook ik its not a common exam board but can you do alevel edexcel chemistry like maybe 2017 / 2018 / 2019 papers as those are the hardest

Mark scheme of Q13 says "Award the mark regardless of response" so I'm confused? If leave the question blank, I'm technically correct?
your explanations are amazing !!! thank you so much

anyone can answer pls
hey i think it's because in the n=m/M equation the mass (m) is in grams and the molar mass (M) is in g mol^-1 xx
What a legend, please try make more OCR A chemistry papers before the 10th of june.
gonna try my best haha

@@HamzaElsharkawy-rb2nc will try my best my g!
@@the-a-level-cookbook thank you bro
Omg if u can do as much as possible I would be soooooo super duper grateful cheers brother
I still don't understand why we divide by two in 17a)i
Its 2 moles of the agno3 in the reactants
So we divide by 2 to get one mole
