It may be just dispersion forces then

I know dispersion forces would be a guarantee but idk if there is another on top of that

But covalent chemical bonds are not intermolecular forces right?

What intermolecular force (s) is (are) expected to be present in polystyrene?

10 units ftw

So a person who is ranked first would remain as first even though he performs poorly in trial and external?

Can someone who is ranking second overtake the first ranking guy if he performs better in the trials and external HSC? And, if yes, can a third place student take first place if he performs better in trials and externals than the first and second ranked students?

Lol okay

^ believe him

I'm dropping physics cause I am terrible at the subject (except for space topics ^^)

I am starting to believe that HSC Chemistry is indeed hard. Hopefully I can absorb information faster.. taking me too long to grasp the concept.

I think it is A as well. C3H6 is part of the alkene group which has a variety of formulas in its homologous series.. like C6H12 so and C2H4. So, I think you're right ^^ im going with the A

Which of the following is both an empirical formula and a molecular formula? * *(A)*CO *(B)*C3H6 *(C)*CuSO4*∙ 5H2O *(D)*NaCl

What textbook do u guys use or recommend for HSC biology?

Yes! Thank you! :DDDDD

Yeah, chem :1

Could someone give me the answers to the water module? Please :)

Scroll down to the PRELIMINARY NOTES section :3

Cool, thank you :)

Thank you guys !
