The TDS one!

Site C has higher conc of TDS cuz:
Soil erosion: so... fertiliser, nitrogen compounds in water
Located near road: pollutants of incomplete combustion from cars (CO, C(soot))
AND Path of water flow: Water could have flowed over limestone (for example) and picked up carbonate on the way.

idk...but thats what i said

 

[sharoooooo]

i done divide

oh
dw lmao, i had no idea what i was doing. so i divided by a billion
*i tried*

 

[akame]

for that one mg/l i think equals to ppm and then divide by 1000 for ppb

ppb is 1mg/1000KG so that means 1PPM=1000PPB and btw there were no pracs in the industrial option right?

not that i remember?

 

[Crazmanis]

Shit. I divided by 1000 for the ppb. That's another mark gone. I though i was gonna get 85/100 and then I see I make more and more errors, and now ill probably get like 76.
I should just drop out of life.

Dude calm down, Others probably made the same mistake too

jesus christ lol

you need to chill

Couldn't remember my cfcs and the equations, so that's s bummer..

what Q?
Are you talking about multiple choice CFC question?

 

[Thesickdogg77]

Please people who did industrial, what is the answer to the equilibrium constant? i got 300 something
and also what did u guys get for the concentration of the weak acid to get the same ph as the strong acid question.. i think it was nitric acid and some other...

 

[sharoooooo]

if it makes anyone feel better, our school hasnt taught us Acidic enviro yet

YES I GOT 300 SOMETHING TOO, omg thank god.... i was so worried i got it wrong!!

Is that acidic enviro question? i havent done that atschool

You just made my day... hahah so happy Yeah it was acidic question i think i did it right but yeah whatever... atleast i got the 5 marks from industrial, hoping for 90+

Likewise

 

[H8]

can someone explain that ph multiple choice with 0.01 something. Can't remember the acid rain prac, what other pracs did i miss.

 

[Anthel]

What about that AAS question...told you guys it would be in the exam.

What was the answer to the ppm question?

I believed you
I studied it
I smashed it

 

[Anthel]

asss if... what school do you go to?

 

[rawrliongirl]

i completely screwed up all the chemical equations :'D :'D :'D my trials have not gone to plan at all :')

 

[sharoooooo]

asss if... what school do you go to?

you dont want to know..............

We did Chem Monitoring first, then Production and now Industrial
Acidic is after trials -.-
....yep :/

Woah! You're doing acidic last?!?! That module is the most heaviest one with the most equations and content to remember... Good luck.

What else stuffed you guys up in the exam?!
