whats the hardest hsc chem questions u've seen and post them up cos judging from all the exams this year itll be pretty safe to say that they'll put some fucked up questions in there.
most difficult one i've seen (not really difficult, just impossible to know if u havent seen it before)
draw a lewis dot diagram for carbon monoxide.
