Chemistry paper 52 ... Some doubts..

[christopher g]

So guys i just did my chemistry paper 52, and i wanted to clear a few things out.

When they ask you to make a smooth line, can you draw a straight line or must it be a curve? And in a question proceeding that question, they asked us to draw a curve if the experiment is done at a lower temperature. Does it necessarily have to be a curve (with bends and stuff)?

And what did you guys get for the last question? What carbonate is the solid?

Thanks!

When they say smooth its usually a curve.And as for the bends its f9 as long as you dont use a scale to draw lines that are suppose to be curvy(as long as they dont ask you to use two straight line).
And how was ur paper?

Paper was fine... Some I didn't answer as well as I should've.. But there is still paper 1 and 3! Are you taking the same exam?

I did 51, we had Ammonium Calcium Sulfate as the salt. And temperature experiments with the first question. Wbu?

Our first experiment was about adding hydrochloric acid to varying concentrations of sodium thiosulphate. A cloudy precipitate will form and we have to shake it till written text can't be seen anymore. I guess we had a completely different paper. What is Ammonium Calcium Sulfate? that's so long.

Oh we had to measure temperature as we add more acid to NaOH and plot as graph. It was easy!
Yeah the salt they brought had two cations and one anion. There was alot of heating and testing for gas with ph.
