Hi, is it correct to say that one of the uses of UV light is that it can be used in:
-Neon signs in billboards
-Fluorescent lamps?
The question is for 2 marks.
Would I get both marks for these 2 points?

TBH I'm not totally sure. I always thought the main uses of UV light was for Sun Tans and detecting forged bank notes, but it is used in both of your answers, so, yes, you probably would get 2 marks. But don't quote me on it ;)

Aren't Neon signs made of Neon? at least that's what I studied.

For the physics paper, was the graph supposed to be a bar graph or a line graph?

Surely that was a bar graph because there we were supposed to represent colors against their voltage required/wavelength (whatever it was) you can't use a line graph with colors. You must have both units like weight against height for that. I hope you understand that :P

Which is why I drew a bar graph :) But I know others who drew a line graph, so I was worried that I was wrong.

Chemistry had a few tricky questions! >_<
I wrote the compound was sodium chloride.. apparently, its wrong.. what was the question exactly?? did they ask for the sodium compound used? i thought they asked what the compound formed was.. most of my friends wrote sodium carbonate.. it was 2marks right??

i wrote sodium carbonate as well because of the fizzing,which doesnt happen when sodium hydroxide is added
