Section I: Multiple Choice (3 Viewers)

[since]

I got 13 for multiple choice
what was the answer to the equilibrium question in industrial chemistry,did it reach equilibrium ?

whoaaaaa 15/15 (according to the answers posted on here) pretty happy with that since yesterday did a whole bunch on board of studies website and got 82%!! lol

1-A
2-B
3-A
4-C
5-C
6-D
7-D
8-D
9-D
10-B
11-A
12-A
13-C
14-B
15-B

Yay HI-5 to 15/15 xD !!!! so happy with this considering my avg for mc is 13 for past papers !!

Personally i have to say 1-9 were so straightforward . The only one that took a little time was 12 and i nearly got 14 wrong.. initially chose C, but in last 30 mins of checking answers adn redoing multiple choice, i realised i did a similar question before and got it wrong last time. Wasn't gonna get it wrong again xD its right that its B, and anyone who says otherwise should reread the topic. *concentration of H+ ions not just moles*

this just in from my chem teacher:
A
B

although it looks like these are pretty much the same as the answers here.

peoples for 13 why is it c, i thought it was d?

Well if you remember tests on the most reactive group 1 metals, they all bounced across the water burning. Which is what Q is described as doing, so clearly its the most reactive.

The highest voltage would come from a really reactive metal with an unreactive one.

So R is described as being less reactive "reacts slowly to form metal oxide" and doesnt form hydrogen. Unlike S.

So Q and R together would create the highest voltage.

Lol guess how i did question 13, i just thought that A and B are the same, so they are both wrong.

then its down to C and D. Q sounds more reactive so i just picked Q, i have no idea what that question is on about. But C seems right after checking with u guys. hah
