Hi there. Love your work. I have a question regarding aluminum oxide. What chemicals or oxides except cryolite, can reduce aluminum oxide melting point if you heat them together in a crucible in a furnace? I know this auestion is not in par with the video above but I dont have your email address. I will appreciate your feedback

Hi, do you think the exams will be easier this year, or are the grade boundaries going to be very low anyway?
@theslashbro44742 жыл бұрын
for the IGCSEs anyway, the grade boundaries for this year are 2019 > x > 2021 (greater than 2021, less than 2019)

Hey dr Donnelly quick question would we have to learn more practicals like marble chips exct for rates of reactions and which from ur experience which practical will most likely come out ? Aqa chemistry rates of reaction
@Freesciencelessons2 жыл бұрын
You should definitely learn the required practicals that are on the main focus playlists for 2022. Any other practicals that I mention in other videos are worth being aware of (as long as they are not in the "not going to be examined" list).

Hi Sir! My comment on the last video got deleted I think, it was a question asking about GCSEs. Do your playlists for 2022 Combined Science Higher cover EVERYTHING and every topic we need to know? Thank you so much if you can respond, love your content! 😆

Will you ever do the immune system please
@Freesciencelessons Жыл бұрын
Hi. I know that lots of students are waiting for that topic. I will be doing it in the very near future. I'm just making my way through the final AS chemistry topic (Equilibria). I have around five more videos to make on that and then I'll be going back to Biology and doing the Immune System.
