So I have to plant something and determine whether it grows better in light or dark. It says to design an experiment to "determine whether a physical environmental factor will affect the way they grow. I've put some under my plants under a lampshade since I live in a really small flat with...
So apparently my careers advisor told me that a scholarship is given to those with atars of 99.90 or something and that you have to be a high achiever to apply for one. Is this true???
I'm thinking of Bridge to Terabithia but I'm not sure if it's "good enough" since a lot of the people in my class are doing thick novels.
I don't know much about other books and I don't think I have any time to read them. :/
Do you think it's a good choice? If it is, is the film version or...
I feel like I've wasted these precious six weeks doing nothing at all. No matter how hard I try to study, I just couldn't focus and I still have heaps of notes to write for each subject. I live in a very small apartment that is pretty much like a wasteland with things all over the place and I...
There are so many ways, and just wondering which one is more correct, otherwise is any process fine? (i.e. hydration, combustion or fermentation?)
PS. Chem is not my best subject =_=
My teacher said that you don't have to memorise them but some of my friends have told me that you have to remember them.
Is it required that I have to memorise them?
I'm just confused as to how it works.
I've been trying to solve this equation: x (2x + 7) , let u = 2x + 7
So this is what I did:
du/dx = 2
du/2 = dx <-- this is where I'm stuck (cuz apparently the right side is meant to be the derivative of 2x + 7 but there's an x in x(2x + 7)...
I've been looking through textbooks, school worksheets and tutoring notes, and their cathode half equations are slightly different to one another. They have something like these:
2MnO2(s) + 2NH4+(aq) + 2e- --> Mn2O3(s) + H2O(l) +2NH3(aq)
MnO2(s) + NH4(aq) + H2O(l) + e- --> Mn(OH)3(s) +...
