hello everyone, i need some help with multiple choice. when i got my trials back, i lost 2 marks in the biology and 2 marks in chemistry due to the fact that i changed my answer. ( i lost more than 2 marks overall but i'm just saying i lost a total of 4 because of this reason). my initial...

Re: What happens to your ATAR if you go to a top 20 school but rank last in a subject If majority of your cohort do exceptionally well, you will be pulled up. But you won't be dragged to the same range as them ofc. So you need to do well too. eg: i know someone who got 19 in phys but got pulled...

it just happens like that. Memorising it shouldn't be too hard since its just combining them both into one :)

at my school, you have to buy a razor from the office to shave your beard.

Turn over your periodic table and look at the standard potential table at the back. The electrode which is higher/closest to the top will be oxidised (which is the anode; since anode = oxidation=loss of electrons) In this case, Ni is anode. (because Ni is closer to the top than Cu)

its just a natural god given talent

oh okay :) Thanks everyone!! :party:

Two identical perfect cubes (similar to dice) each having faces numbered 0,1,2,3,4,5 are rolled. A score for the roll is determined as the product of the two numbers on the two upper- most faces. If the cubes are rolled twice and the scores for each roll are added, what is the probability of...

great :) 87%

to figure it out, write the oxidation numbers for each compound. then compare the oxidation numbers on each sides and find then u can find the oxidising agent. so... for this question, on the left side, H+ has an oxidation number of +1. but if we look on the right side and find 'H', it has an...

ahh i see now :) thank you so much!! :spin:

hes probably just sussing you out give it a few more months (years) and maybe he'll warm up to you

In how many ways can four consonants and three vowels be arranged in a row: a) so that the three vowels are always together b) so that the first and last places are occupied by consonants? pls help me, I've just started doing perms and combs and im lost :confused2: The answer for a) 720...

ohhhh lowest i am so careless!! :(

Hey everyone, how'd everyone go for CSSA chem? I just want to compare with other schools' results... :) So, how'd you go as a percentage and what was the average for your school? edit: i got 75%. our top mark was 90%. not sure what the average was but ~60%ish. Im at a ~120 ranked school too

the higher up the table, the easier it is to be oxidised. therefore, the anode M (where oxidation happens) must be above zinc on the list. looking at the list, CALCIUM is the highest on the list above Zinc which means that calcium is oxidised so we flip/reverse its potential from -2.87V to...

it just says "assess". So just pros and cons on the impact on society and the judgement is enough. historical timeline of events isnt necessary but maybe you are learning it to aid your understanding of the Manhattan project? :)
