Thanks :)

Plz answer.

Yeh i wrote it was parallel and linear trend since controlled just inaccurate.

Oh and I wrote all the variables and showed the controlled variables.

Thanks. Oh ok so how much?

Thanks :)

I wrote not the same concentration in industrial process with not the same conditions i.e. temperature and pressure. Also wrote that nh3 is added and no ammonium crystals in the industrial process- is this ok for the 3 marks?

OH BTW GUYS: if i did ammonia saturator for model: 10 mL of concentrated ammonia solution (30%) was mixed with 10 mL of brine . 10g of ammonium chloride crystals were dissolved into the solution, and then more continuously added in excess till no more dissolved. The clear solution was then...

eyep

They wont care. Mark for the hcl equation, hcl use of moles, conversion of moles in the co2 equation and then finding correct percentage. but if you over did it they would.

Oh ok. It showed a linear trend and it was almost parallel to other line hence indicating that the variables were controlled and the heat loss was only adding to inaccuracy of the thing. Hence valid. Although you can argue that the thermometer was not placed in water but rather the beaker but...

sorry. I screwed english in hsc.

thanks popcorn.

I wrote that so2 is being shown adequately and wrote equations for formation of acid rain and then showed by linking to the model that the formation of acid rain is not shown although the ph reduction is shown and the realistic concentration is not seen in the closed system of so2. I wrote a few...

Its not a direct use. You dont use ethene as a material in itself. You have to make some polymers with ethene but ethene is not a thing to be used by itself.

Now safe phew.

Yeh emilios I said solvent is fine. I said dehydration is not bahahaha. Please read again (if you want to).

Same. Except the ones where you dont have much to write underneath cos supervisor got pissed and wrote like 2 pages for soap. hopefully they dont say coherence or something.

Whattttt??? the borders of lines or the borders of page?

agreed. They will make it hard. BTW is pentanol toxic and do you wear a fume mask? I didnt know what you wear for pentanol use for pentyl butanoate hence I said pentanol uses a fume mask. either waay you dont conduct the experiement in fume cupboard so didnt write that. bahahaha. I jsut wrote...
