Looking down the list, I think they are all relevant to HSC level chemistry. At our high school, the teachers didn’t teach the SPDF rules and notations and told my kids it wasn’t part of the syllabus so no one in the classes learnt it (including my kids even when I offered to explain to them) which is a shame because understanding these concepts helps with understanding the transition metals whose properties don’t conveniently follow rules from left to right as the elements towards each end of the periodic table do.
Anecdotally, I once marked a postgrad exam paper, in which, the candidate obviously knew absolutely nothing about gravimetric analysis and made up complete rubbish about measuring gravity which was simply a waste of their exam time. If they had studied this concept at high school, not even undergrad, level, they probably would have scored a mark or two.
