Re: How can we determine between strong/weak acids and bases based on chemical formul
Simple answer:
HCl ionises to a greater extent than HF.
HCl completely ionises to form a hydronium ion and chlorine ion:
HCl + H2O -> H3O+ + Cl-
whereas, HF only partially ionises to form a hydronium ion...
nah it's good your aiming high, but those marks are exceptional.. I don't know you, but I'd say they may be unrealistic.
95 in all subs is achievable, difference between a 95 and a 97/98 (state rank) is huge..
