Percentile rank: 97.3 Congratulations to Kami! :)

I don't think guys are as likely to compare themselves with randoms on the street. For guys, there's a wide variety of attractiveness. They can be skinny, normal, chubby, etc and still be considered good-looking. However for girls the universal ideal image is big breasts, long legs, toned...

I try not to think about it. But yeah, I'm really scared.

PHB is quite easy to remember. PHB all the way. :) Click me and me.

Remember that no radioisotope emits ONLY gamma radiation. Both technitium-99m and cobalt-60 emit beta along with gamma.

Girl 1 is obviously not interested. But don't do the take-what-you-can-get thing. If you're going to go for girl 2 only because you can't get girl 1, then just stay single instead of becoming involved in a relationship you might not even want. If you've tried asking girl 1 out for two years then...

My boyfriend told me about it yesterday. I watched 10 seconds before I closed it. Words can't express how disgustingly barbaric those people are.

There are already a number of "study tips" threads, but I guess the more there is, the more likely people are going to read them. :p For some other ones, see below: http://community.boredofstudies.org/showthread.php?t=65201 http://community.boredofstudies.org/showthread.php?t=3734 My...

Place a folder or cardboard around the apparatus to minimise heat lost to environment. Stir the water while being heated to ensure even heat distribution. Place tip of flame close to the beaker so that little heat is lost before it reaches the beaker. That's all I can think of from the top...

Calm down, kids. From your posts, I gather you'll all be just fine. ;) Just because you still feel nervous before exams, and there are still several questions you need to ask in class, it doesn't mean you're not doing well. It's hard to feel like you're on top of everything all the time. As...

I think we're all in denial. Dumbledore is dead and Sirius may be trapped behind the veil, but he's as good as gone because he's not going to come back. Snape explained why he offered Harry protection throughout these years - because he needed his job as a teacher at Hogwarts for as long as...

I'm making an educated guess that the equation of the reaction is: C2H2O4 + 2NaOH → Na2C2O4 + 2H2O Since oxalic acid is diprotic: (C1V1)/(C2V2) = 1/2 (With 1 being oxalic acid and 2 being sodium hydroxide) I'm assuming that 3.00 g means 3.00 mL, because if you meant 3.00 g of pure...

It is quite a strange task. You need to know how to calculate the molar heat of combustion of fuels, but the "keep you alive for 4 days" goes a little too far. :p Don't worry about it too much. Of course, if you can get your hands on a data book, then do so.

Yes, the molar heat of combustion increases with molecular mass. You can compare the amount of CO2 produced by writing equations, assuming they're undergoing complete combustion. For example: CH4 + O2 → CO2 + 2H2O Whether or not it combusts completely depends on the reaction conditions...

There are four chlorine atoms, therefore it's "tetra-". You're right. It can't be grouped as a hydrocarbon because hydrocarbon, by definition, contains carbon and hydrogen. It's called a CFC (chlorofluorocarbon) and you'll encounter it later in module 3 - monitoring and management of the...

Just a note. If you don't do Biology or Physics, and avoiding the Forensics option is possible, then avoid it. The only science I study is Chemistry, and I found I had to put in extra effort for Forensics because I wasn't as familiar with DNA, proteins or mass spectrometry.

First official boyfriend at 15, or maybe 14. First love at 16, and still going.
