How did you guys go on the 6 markers? I thought they were fairly starightforward, Einstein was good, and I did Westinghouse for the external ideas one, was good :D

Agreed. I cant say it was dead easy but medical physics was so simple. I only screwed up the radiopharmecautical question.

Same here lol, didnt put much effort in, could possibly scrape a 70. And its an hour after physics..

Acid rain is that has a higher hydrogen ion concentration that normal-higher, that about 10^-5 mol/L. This occurs when sulfuric and nitric acids react, as well as the oxides, such as carbon dioxide, which turns it slightly acidic. Effects inclue: - Increasing acidity in lakes - Damage to pine...

Here's one for fun. Identify this molecule, and its effects on society (hint: 60's). Sorry couldnt make it smaller lol.

going through piles of notes here.. A buffer solution is a solution that contains comparable amounts of a weak acid and its conjugate base and which is therefore able to maintain an approximately constant pH even when significant amounts of strong acid or strong base are added to it. In rain...

Yep, thats very similar to what I was thinking. I dont like these 'real life' style questions.

More ext. response, sigh. Q27 - A sports magazine commenting on the athletic ability of Michael Jordan, the famous baskeball player said: 'Being an athlete takes more brains then brawn. It takes time and effort. It takes endurance and commitment. It takes an athlete who can stay in te air for...

This is when you start stirring. My prac for this failed, as the teacher gave us 6M! of HCl, hence the spatula started dissolving in the solution. Stirring it helps dissolve the solid slightly. edit: yeah danz pretty much nailed it

I smell a forum troll

Im ready for sure. Just need to go over a few pracs again.

Same here, just get spammed with the lot at the end -_-. Btw why is this the exam thoughts for chem up so early? 3 days to go.

I'm sticking with Americium 241, but how recent do they need to be? I've always used it as my transuranic element (sigh i know like 10 different ones due to two medical uses in physics).

AC generators allow for the production of AC electricity which can be supplied to the public. This affects society greatly allowing for lights in houses and streets, and many other electrical household appliances. It has affected the environment because of the required infrastructure that has...

Such violence, I suggest go for a paddleboat ride.

Ypu dont know what year he is in. He might be doing this stuff in advance. If he's sitting the paper in two days like us...well, yeah, no comment.

I think its parallel, as cos0 = 1 and cos90 = 0

anode: Zn ----> Zn(2+) +2e cathode: NH4(+) + MnO2 + H2O + e ---> Mn(OH)3 + NH3 the carbon graphite rod is the cathode. the zinc casing is the anode. the C, MnO2 and NH4Cl im pretty sure is the electrolyte (the paste is like a mixture of the 3)

Wow that one is great, and its extremely recent as well. It looks very complicated haha. Anyways im off, need to do some study for SDD tonight, as it is in 2 days, JUST LIKE PHYSICS ON THE SAME DAY GRR.

Well i decided to do bipol at the last minute, my teacher mentioned something about radon? wait, isn't that some form of ratsack? LOL. Just found it, rayon, reconstituted cellulose, treated chemically to make fibres tha can be used to make fabric (as its useless to start of with). It doesnt...
