Which course should i do B engineering (chemical) or B engineering (materials science and engineering) @ UNSW or B engineering/B science or B engineering (chemical and biomolecular) @ usyd What jobs would be available for me if i do the course How should i rank my uac preferences if i...

Im choosing what i want to study and i was wondering what maths do engineers do in their course , so far for my hsc i have scored high in science subjects , english and ipt but my math skills are a bit low

do u know where they got this qs also how does polarity effect the reactivity wait so the greater the cell voltage produces = electrons more readily oxidised = more reactive element

There was this qs that had 3 galvanic cells and with unamed elements attached to Cu electrode and had a table with their cell voltage and polarity with Cu. How do we work out which elements are more reactive.

i think the answer is C cuz 1-butanol has the third largest molecular weight and as all molecules used are polar their polarity would not have much difference in the result

Hi can anyone verify if my topic concepts are about into the world they are An individual’s values and interests can conflict with new experienced due to being forced into the world. Different pathways influence the transition into new phases of life for individuals The...

Does anyone know any examples of Australian terrestrial plants and their adaptations in minimizing water loss (other than eucalyptus) and can u plz explain how these adaptations work? Also 4 spinifex leaf rolling is an adaptation, what is leaf rolling and how does it work?

i know how to calculate the concentration of a single acid or base in a titrated mixture but i want to know is how to find the concentration of the entire acid-base mixture together * heres the sample qs that bugging me* calculate the concentration of the mixture where* 500mL of 0.1M of HCl is...

Jst wondering how everyone goes through an exam I start with multiple choice and spend 30s on each multiple choice qs usually get at least 18/20 Then i answer the short answer qs What i want to know is what is going through ur head when u answer a bio exam? what is the most effective way...

Jst wondering how everyone goes through an exam I start with multiple choice and spend 30s on each multiple choice qs usually get at least 16/20 Then i answer the short answer qs i 1st planned and wrote sidenotes on what i knew on all the long ans qs Then from the side notes formulated an...

However if you look at the boiling point of esters with same no of carbons such as ethyl butanoate and butyl ethanoate butyl ethanoate has a slightly higher boiling point - why?

Hi for esters with the same number of carbon atoms in the molecule which side (alkyl group or the anoate) part of the molecule determines the esters boiling point and why?

Jst wondering if u lift weights will u become shorter? Cause I was thinking about increasing the amount of weight i am currently lifting but i dont know if there are any bad affects of it

what do u do at the tutoring sessions at dux college , i was thinking about joining cuz my friend goes there and is getting really high in chem and physics

In a practical exam we had a question on the fermentation of glucose to ethanol , why the mass change stopped at a given time would it be fair to say that due to the limited amount of active sites on yeast only a limited number of glucose molecules will react to the yeast? Also would ethanol...

Ok so heres the question An electrochemical cell is constructed using two half cells. One half cell consists of an inert platinum electrode and a solution of Fe2+ and Fe3+. The other half cell consists of a lead electrode and a solution of Pb2+. If u want to see it , it is in the 2009 HSC...

need the notes guys

There is a galvanic cell in one of the past hsc papers where it uses a Ni and Pt electrode as well as Ni and Fe electrolyte solution Im just wondering why Fe+3 cannot make Fe solid it instead makes Fe+2

Would u need to study and know the prelim topics for biology for the hsc
