re: HSC Chemistry Marathon Archive Dilute sulfuric acid is already ionised so it can already attack metals eg steel containers. Concentrated sulfuric acid is all molecular, hence it reacts vigorously with water so using steel containers is ideal since it prevents moisture from entering and...

re: HSC Chemistry Marathon Archive You don't have to calculate anything for any of them apart from writing the equations. By moles = mass / molar mass, the substance with the LOWEST molar mass produces the greatest moles of CO2 (as molar mass decreases, moles increases since it is a 1g...

85 aligns to a 93* sorry :lol: but if your figures are right then you are correct, yes.

I personally found q16 harder this year thoughts? MC was quite straight forward, got stuck on Q9 Anyone else school started earlier? we had everyone there ready anyway *EDIT* HAHAHAHA I DONT EVEN DO 2U!! Hijacked by the #General#Mathematicians

What is the standard cell potential for the reaction of 1.0 mol L−1 acidified potassium dichromate (K2Cr2O (aq)) with aqueous sulfur dioxide (SO aq 7 2( )) under standard conditions? (A) 1.20 V (B) 1.52 V (C) 2.24 V (D) 3.20 V Only one i don't understand... 2014 paper btw On another note...

It was 8% per year, so declining balance Either way, C,D should have been ruled IIRC because they reached 0 (you can't reach 0 if you decrease by a %) then it was A,B.. One of those had wrong values (try calculating it for n = 8 years for example and see if it matches the graph)

87 is way too high I'm expecting 83ish~ Did anyone get barely any D's for multiple choice btw? or is it just me ...

finished with 1hour 20 mins to go MC was easy, checked it twice and only not sure about 1 question which I know is easy.. I checked all my answers for Section II, but I didn't get the last question..I drew all over the diagram and couldn't read anything anymore fmd..only figured it out once I...

If it means anything I can show you how to do it using Python, haven't used VB in ages... follow astroman's link or programmers.stackexchange, whichever...

Drop to SS then and state rank it If you find IPT boring then it will drag your motivation to study and that's the worst thing you want... But remember, you need to atleast band 6 SS or state rank otherwise its scaling will impact you My regret is not picking senior science and getting an...

1. Get out your calculator 2. Know that x / x = 1 3. Type in 0.666666666666666 / 0.66666666666666987654321 (15 sixes divided by 14 sixes + 987654321) 4. Press = 5. Accept that your mind = blown 6. Re-evaluate life choice

gg my tomatoes got infected with parasites again 50 atar inc.

link is dead reported for misleading information.....again

yes you absolutely can math might hurt you abit, but definetely..80 + even..

My masturbation record is 1 hour and 32 seconds. I love daylight savings

Not planning on med but just curious I know someone who did 1 year of medical science then went into med. How does that work? Do they factor in your GPA + UMAT result, or GPA + Atar + Umat result? OR highest of the two or what not?

-GmM/r gives you the gravitational potential energy at a specific point for the object in space. Thus if you use -GmM/r you need to use it twice (final - initial) since you are after change in GPE. Using e=mgh gives you change in gpe but assumes 'g' is constant (g is not constant because it...

Question 18 should end with "What is the total payment Jo receives each fortnight" rather than "What is the total payment Jo receives each fortnight from the government?"
