I finished my trial in 1 hour, but this took me 2 1/2 hours. I spent the last half hour going over my short answer Qs and stuff.

1 got 2 as well.

Normally the first one is a bit higher because you overshoot the equivalence point.

I said there may have been a mistake in the titration, one value higher than the three others. This would have increased the average concentration and made the calcium concentration seem higher.

55 kids in my year walked out after 1 hour, some of them do 2-Unit as well

lol :rofl:

You think I should chill out? I'm not the one who swears every second word.

What's wrong with you? Sure, the exam was much harder than previous years, but it's pretty disgraceful that you make some lame joke about a girl committing suicide and using it as evidence that exams are harder. Take a deep breath and sit down for a few minutes.

As far as I know, Xenon produces Xenon oxide Xe3O2. I'm not sure what kind of oxide it is, however.

What do you mean? :confused:

A condensation reaction is a polymerisation reaction where two or more monomer units join together and a small molecule, often water, is eliminated. An example is the polymerisation of glucose, to make cellulose and water. A dehydration reaction is a reaction where water is removed from a...

Re: Who have Chemistry LASt? Me too :wave:

Wrote 23 pages for essay. Rest was easy. :) Still got one exam to go. Damn Chemistry!:burn:

I'm pretty sure it's a line of best fit. Chances are if we get a graph to do, there'll be one outlier point. If you ignore it, you should be right. However, I'm not 100% sure.

Advantages: allows complex molecules like glucose to be viewed and allows students to analyse their structure clearly shows how isomers can be made using differently coloured balls for each different molecule, structure can be seen single and double bonds can be clearly viewed shape can be...
