I messed up on the ideal gas equation question. What did you get for the empirical formula of the compound produced from ethene reacting with oxygen?

U had to calculate the volume of ethene in the ripening room. As it was 100ppm, u would divide the full volume by 1 million then multiply by 100, then use pv=nrt to find n which was 0.91

do you think the grade boundaries will be higher or lower than last years January paper? I did that one and found it really easy so was surprised that for an A you only needed 60 / 80

Edexcel’s really inconsistent with its UMS conversions. In 2014 papers u had to get full raw marks to get full UMS. I think we’ll have to wait and see...

it's okay, I guess. Edexcel is a little sick in the head lol. I think the gt will turn out to be real low or something. personally, I feel that this paper was real easy. I finished it in an hour. I believe miracles do happen 😂 btw where are y'all from
