Guythsss do projectile question from 95 paper. Pretty different to standard types of questions you get.

Dude its 0.34^x 0.17/x^2 Your answer is wrong

Creepy

Pls refrain from making connections with such a horrible subject.

You wont get marks for writing more equations. In fact, it's risky writing more than 1, what if one of them is wrong. You lose marks. I think they won't deduct marks if you've written more than one question provided they are correct. Nor will they award extra marks for extra equations

Chemistry notes have been added guys :D option - industrial

yeah i also did it graphically!

Yes i agree! you had to talk about how aspects of the experiment was valid and not valid. You had to talk about experimental method/ trends and the stuff you mentioned previously

8 is B, read the question. I also fell for it

The paper wasn't hard, relatively easy in comparison to other HSC papers. However, what I am scared of is this chemistry marking criteria! It's going to be so harsh.

What 3 marks? dw you'll do well :D 3u tomorrow

liar

State rank is higher

State rank - 97+ raw

yes. Very unique question, never came across one like this

The answer is Y because the anode in all cells are chlorine, therefore ruling out X immediately. The cathode in a mercury cell is an amalgam, not just Na therefore z is ruled out. The cathode in y = correct

This was a relatively easy exam in comparison to past years. HOWEVER do not be so sure that you will get 90 raw or higher, we have no idea of the marking criteria but we do know that it will be harsh like it always is.

Reliability is whether or not you repeated the experiment. Validity encompasses whether the experimental method was correct and if all variables were kept constant except for independent variable (minimising errors as well)

If you learn by yourself there is most likely going to be holes in your information since you do not know what is important or not. And then when a teacher explains you're most likely going to be like "I already know this so ill do something else during class" and you miss out on some detail...

Everyone know how to draw cellulose?
