I agree, a significant amount of chemistry below A-level was just wrong (although they said so at the time but were obliged to teach us it incorrectly so we’d pass the exams).
Good job you didn’t do a degree in it then :p a-level was just another set of lies, and you now have to learn a different set of lies* for each branch of chemistry.
*they’re then refered to as models, the GCSE one is actualy perfectly valid and fits everything, it just doesn’t go into enough detail to explain everything.
Only things I can think of that were actualy wrong were;
– Adiabatic expansion and cooling as explained by Geography teacher.
– Galvanic corrosion/electical potential by a chemistry teacher
– Entropy, which is actualy a very simple concept, but they insist on leaving it as “a measute of dissorder” which explains nothing!
– the grooves in car tyres are there to decreace friction and slow people down, technicaly true in F1 I suppose.
