i found that alright
i didn't like section 1 at all, but paper 2 was really easy imo
what did you guys put for the very last question? my friends keep talking about something to do with limewater being turned cloudy, but i wrote that you could test the pH to find out which is more acidic, which would tell you which one contained more, and i also wrote that they could perform a titration calculation, with the average amount needed to neutralise each time telling you which one had more



i've seen it labelled both ways in my notes
i debated between the two, and i think i chose ion bridge, but i think they refer to the same thing anyway


I wrote it something about limewater turning cloudy. I wrote something about density as well.

Did anyone say gold was a catalyst?

Yeah I think so
See for the redox question did you Just have to cancel out the electrons because both were 2

The first open ended question was very easy imo.

The second one was a bit :/

Yes


I talked about limewater and if you were to boil it, the rate of evaporation.

I think it was question 2 , was the answer pyramidal

How did everyone find that? I found it okay, not too hard, but not very easy either haha
I put Salt bridge instead of ion bridge, will I still get the mark?:/


I can remember doing a past paper and it said something about a salt bridge next to the ion bridge in the marking scheme, maybe it was wrong, maybe it was right :P

Try checking the previous past papers for credit and int 2, cause I saw it in one of those papers.

Yes, I got pyramidal. I was gonna put tetrahedral, But changed my mind.

I think it's right.

Yep :biggrin:

The last question for MC was a bit weird. What did you all put down for it? I said A Lithium ions, But it was a wild guess lol
Did anyone put ethene for the alkene with the structure that was 2 carbons 4 hydrogens and a oxygen?

What did yous all get for the 1st question on mc: I got (s) + (l) = (Aq)+ (Aq)
