Thanks!

NO2(g) + O3(g) → NO2(g) + O2(g) 0.66 g of NO is reacted with 0.72 g of O3. n = m/M The molar mass of NO is 14 + 16 = 30 g, therefore we have 0.66/30 = 0.022 moles. (Note that I didn't round off) The molar mass of O3 is 16 x 3 = 48 g, therefore we have 0.72/48 = 0.015 moles. (Note that I...

Wow... Can you post up the question and the correct answer?

Is this what you're talking about?

At 0°C and the pressure of 1 atmosphere, one mole of any gas will occupy a volume of 22.41 L. At 25°C and the pressure of 1 atmosphere, one mole of any gas will occupy a volume of 24.79 L. So yes. You just shove the number of moles into the formula. Moles x 22.41 or 24.79 = volume. The...

Never round off during calculations. In most cases you would round off to two decimal places. Use the memory function in your calculator, don't round off before you get the final answer, and you should be fine.

Generally, you go by the numbers in the question. If the values given in the question were rounded of to one decimal place, you follow suit and round your answer off to one decimal place. If no values were given, you should be fine rounding off to two decimal places. Read questions carefully as...

$30 per hour is not considered "cheap" for fresh year 12 graduates. You can try reduce the price by as much as half, and once you earn a good reputation you can start raising it. I charge $20 per hour for Chem tutoring and my HSC mark was 95.

This is what Mr. Wiki has to say: http://en.wikipedia.org/wiki/Cycle_of_erosion. However, this doesn't seem to be in the syllabus. The closest thing I can think of is eutrophication.

Oh, I was going to do one for Bio, but then some Pharm people advised me against it. Well then, have fun in your bridging course!

I also suggest you choose a medical radioisotope - there's just a lot more to say, IMO. The question said "choose an industry" which confused me for a second, but medicine is an industry. Some medical radioisotopes (since it was given in the plural form, you could write about all of them) are...

Dudette, I feel more intimidated by you! You and your excellent UAI. I bet you beat me in Chem anyway.

The WEA one. I'm not aware of any other prep courses.

Hahahaha, "Sydeny".

So I'll be seeing Frootloop and Leila this year! Haha, I'm flattered, AL. Looking forward to it!

Yay! B Pharm, or just USyd?

B Pharmacy at USyd, HECS place.
