When calculating the heat of solution, do we include the solute in the value for m in ΔH=-mCΔT?
Like if I dissolve 5g of NaCl in 100g of water, would m=105g?
I was just reading ahead for maths and I came across the binomial theorem (which I can't find in my Cambridge 3U yr 11).
I'm pretty familiar with using Pascal's triangle to find the coefficients but I just wanted to find out how this formula works.
Could someone explain what the n over the k...
Just sneak a $50 note into the teacher's pocket and play it off like "Oh! How did that get there?" (Teachers aren't paid enough so its all for the greater good :)
In all seriousness though, It's fun to just strike up a conversations with teachers about what they did on the weekend, etc. As long...

I personally can not imagine dropping any of my subjects but I know people who know exactly what they want to drop.:spzz:

Last night I only had 2 hours of sleep and all today at school I've had heaps of energy. As soon as I got home the tiredness hit me like a brick and I had an hour nap. Feel so groggy :mad2:
Sadly this is what I did everyday last term
I have a tendency to hate the subjects I do really well on. I'm ranking first in SORII and English Advanced despite the fact those subjects make me want to shoot up the school. :punch:
My favourite subject by far is Chinese because I already know pretty much all of it from Cantonese hehehehehe
