Im sure there are others in a similar boat...
Well here is the story...
I got a UAI of 96.75 and had my first few preferences as Engineering Space courses at Sydney Uni. After more thought i decided i did not want to do these but instead do Engineering/Architecture at Sydney Uni which ended up...
got the question in fron of me.
It is an exothermic reaction ( enthalpy is negative ).
increasing the temperature causes it to shift left towards the reactant. Therefore c) is not correct, d) is the answer.............
it is asking what will make it shift to the right.......
What did people get..
20mL of 0.008 Mol/L HCl is mixed with 30 mL of 0.05 Mol/L NaOH.
What is the resultant PH.
how i did it--->
n(H+ in HCl)= 0.02 x 0.08 = 1.6x10^-3
n(OH- in NaOH)= 0.03 x 0.05 = 1.5x10^-3
1.6x10^-3 - 1.5x10^-3 = 0.1x10^-3 (H+ ions left...
does any 1 think they will take sig-figs into account for any of the questions, i used them for all of them accept the ones about fuels. Thought it was stupid to do 3 sig figs on like a 10 digit number
ooh that was the only question i wasn't sure about. I used the Cl2 gas porential, times it buy 2 and added it to the +ve nickel one. That meant i got a voltage of about 2.9X volts, dont quite remember. What did evry 1 else get?
I talked about CAT scans, compared them to normal non tomographical xrays and showsed how tomography made it much better. Talked about MRI and PET scans and how without tomography the data would be useless.
