Hi, I need to ask for Q1.2 the answer in the calculator "4.04040404 x 10-10" would it be acceptable to use this exact answer in Q1.3 because you have used the rounded value but in other videos where a table was given and you find k you would use the exact value given in the calculator to find the other concentrations. And also in Q1.5 can we say "greater than or equal to activation energy" or should we just say "greater than activation energy" because in markscheme I see > with line at the bottom. Thanksss!!
When you're giving your final answer to the question, regardless of the topic, AQA requires you to give it to the lowest number of significant figures given in the data, unless stated otherwise in the question (e.g., give your answer to 3 sig figs). When doing calculations and writing workings, you can of course use the entire long number e.g., 4.04040404 x 10-10, and when using the answer in later question calculations you should use the full answer too (to be more accurate). Yeah sure, greater than or equal is fine :)
Have you got any particular questions from that paper in mind? It takes a really long time to re-write all the questions out so I wouldn't really have time before the exam to do the full paper on top of all the other requests I have :( I saw your request for enthalpy change practicals tho and will get to it if I have time :) Thanks for ur comments and support

absolute lifesaver oh my gosh
Where can i find the questions that you go through in your videos. Are they from a specific website?
This is from an AQA past paper but I've just put it into my own words etc. to avoid copyright.
Can you go over redox titrations please?
sure, I'll do my best to get a video out for redox titrations. I have a lot of requests that I'm working through so can't guaruntee it tho :(

Where can we find the Alevel papers from 2022 last year as I can't seem to find them on the AQA website.
They haven't been officially released by AQA yet, a subscriber sent them to me
Can you go over aqa a level chemistry paper 3 2022?

@@easymodeexams33 No worries, Q2 on the paper is related to the enthalpy change practical.Thanks
@@gaanavmanyam9214 do u mean Q1? Q2 is about empirical formula and tests for ions
@@easymodeexams33 yes sorry, got mixed up.
@@gaanavmanyam9214 no worries man
