It goes to completion because it's a neutralisation reaction. All neutralisation reactions (base + acid, regardless of strength) is a forward reaction that produces a salt and water. The salt can then further dissociate / react with water to produce hydronium (making it an acidic salt) or...

^ ? When do we fill out the UAC stuff? Did you guys find school to be a lot more chill? What should I be expecting lol. Trials just finished and I'm bored.

re: HSC Chemistry Marathon Archive No, I lost a mark because I included the (aq) subscript. They said the equation wasn't necessary. And yes, but by extension, the solute will be able to dissociate into free ions. "An aqueous solution is one that is occurring in water. What makes water...

re: HSC Chemistry Marathon Archive http://imgur.com/RjSSKRJ Marking criteria said it is a forward reaction- but I completely agree with you. Aren't weak acids always in equilibrium? Or did Arrhenius say something about this?

re: HSC Chemistry Marathon Archive Guys, If you were to write an equation to dissociate acetic acid, how would you do it? Because I thought that most acids and bases (all of the HSC prescribed) were aqueous, but isn't it redundant to say: CH_3COOH_{(aq)} -> CH_3COO^-_{(aq)} + H^+_{(aq)}? (yes...

+1, my bad ahaha. Assumed OP was a 2016'er doing the water topic in prelim (prolly cos of the title) Yiis, so a (slightly) more indepth explanation of Librah's answer is that when an equilibrium encounters a temperature, pressure or concentration change (generally we talk about those three...

Yoooo Temperature will increase solubility of the substance. This is because an increase in temperature leads to an increase in kinetic energy (since temperature is really just average kinetic energy of the molecules). Since molecules are vibrating fast and moving more quickly, they're more...

YO guys! Anybody seen any particularly good Mod C essays floating around to do with the People and politics elective? Preferably one that includes the core text Reynolds Why weren't we Told? ALSO: the rubric mentions the module/ sub-topic is inclusive of 'conflicting perspectives' however...

Re: 2015 HSC Economics Marathon To what extent do we need to know about Keynes/Keynesian economcis? (and what can the gaps be used to explain?)

Re: 2015 HSC Economics Marathon Why is the Current Account equal to the Capital and Financial Account under a floating exchange rate?

Re: 2015 HSC Economics Marathon lol ekman can i spam you with questions in your pm? :D

Re: 2015 HSC Economics Marathon @ the supply of AUD question. Found a paragraph in Riley's textbook but don't understand why it works the way it does: "The supply of the AUD is derived from the demand by Australians for foreign goods and services and the purchase of foreign assets." Why is it...

Re: 2015 HSC Economics Marathon I was referring to the immediate effects lol. As in- imagine the RBA wasn't there. Will there still be a correlation?

Re: 2015 HSC Economics Marathon By an increase in supply do you mean in the domestic market or the international financial market? And if more Australians are investing on a global level>> why does it increase supply? Do they inject more AUD into the system? Can you refer me to the relevant...

Re: 2015 HSC Economics Marathon Another dilemma (to do with interest rates) I know there's a cause and effect with interest rates and inflation, i.e: When interest rates are lowered, the rate of borrowing is lowered allowing more people to borrow money and spend. This increases inflation as...

Didn't hpf get like 100% in all her in-school assessments? Think I read that somewhere here lol

Re: 2015 HSC Economics Marathon Either past HSC or school past papers, can't remember haha. How does "the demand for foreign assets such as shares, real estate, government bonds and currency by Australian residents" affect the supply of AUD? I get demand and supply mixed up a lot. Is it ...

Re: 2015 HSC Economics Marathon From the 2015 Riley textbook. Was just looking for more info because sometimes one of the question in the MC presents something about overseas migrants and ask you to slot in where they'll fit in the BOP.

Re: 2015 HSC Economics Marathon In the Capital account , what is 'capital transfers from people migrating into/out of Australia'? What's the difference between workers remittance (which is counted as net secondary income) and this? Can't find too much clarification on this :(

Just bought, amazing notes + responses. : )
