Chemistry Formula (1 Viewer)

[LegendaryGeek]

Hello all,
does anyone happen to have a list of all the chemistry formula needed for the core topics and industrial chemistry? Would be a great help as I have my chemistry trial tomorrow and I don't think I have all the formula!

Thanks all,
LegendaryGeek!

Don't sit there and memorise forumulas...

 

[LegendaryGeek]

But if I don't memorise formulas then please explain how I am supposed to do calculations???

What kind of formulas are you talking about?

 

[seventhroot]

do you mean like the balanced equations and all OP?

If he's having trouble with that, god hell him

Fisrtly, I'm a she not a he, just wanted to clarify.
Secondly, so far I have found the:
pH formula
moles formula
heat change
parts per million concentrations
and the solubility rules

Can anyone tell if there is anything missing?

didn't know this was a formula

Anyway yeah

C1V1=C2V2
C=n/V
D=m/V

Density, moles of gases and particles

Density, moles of gases and particles

How do i do those ones? I can't remember my book that had them in it got destroyed so i don't have them written down anywhere :/

Density = Mass/Volume
Moles of gases = mass(gas)/24.79(RTP) or 22.71(STP)
Moles of particles = No of particles/Avogadro's number [I have never seen this ever used for the hsc]

used all the time at uni.

Believe this is given in the Data sheet

But not the formulas, OP wanted the formulas

 

[LegendaryGeek]

ok thanks guys, now i just have to remember all this plus you know everything else by 9am tomorrow!

What have you been doing this entire year if you don't know how to apply these formulas or remember them?

 

[LegendaryGeek]

i know how to apply them but i have a terrible memory at the best of times let alone when highly stressed because of exams, its the night before and already i can not think straight so that is why i am asking for help so that i can give myself (and others who look here) the best chance for my exam.

 

[seventhroot]

maybe not trying to learn everything the night before is a good idea.

well now you know so learn from your mistake

 

[LegendaryGeek]

im not trying to learn everything the night before, as i said i have a terrible memory so I'm just trying to make sure i have everything i need to know
