Can someone explain to me why heat of combustion increases as carbon chain length increases? I know fire sure that it is something to do with more moles of co2 being produced in the products, but not entirely sure as to the full reasoning. Pls help clarify this

its catholic schools who dont bother making their own papers

i just did the 2012 3 unit hsc and scored 64/70 raw what hsc mark would that equate to

idk...

please someone pm me the cssa 2015 3unit

what would be the top mark in say a top 30 school for cssa

school rank ~100 chemistry : 5/40 physics: 5/40 3u maths 1/60 4u maths 1/20 english 15/85

so a person who does 3unit but not 4 unit (say if they accelerate 3unit and work hard for only 3unit) is at a disadvantage when attempting to state rank?

for example say for mathematics extention 1, does anyone know how state ranks work? like they pick top 10 but im sure there are more than 10 people who get 100% externals.( assume all state rankers are first internally)
