I am confused with the term 'displayed formulas'... is it the same as polymerisation displayed formulas or is it different for molecules?

For example, I have to draw a displayed formula for HF. How do I do this? Sorry if it's quite easy, I just started AS level chemistry and the last time I've drawn a displayed formula was back in Core Science which I took in Year 10.

Displayed just means that you show each individual bond and atom within a compound, so HF would be H-F.
Hope this helps

To add to this they can be really picky, you even have to do it with stuff like O-H rather than OH otherwise you'll lose the mark, make sure you do every bond.

It also says I have to use my knowledge of valencies?

You have to write the correct number of bonds.
