    Chemistry: Post your doubts here!

    Ah, if that's what you're using then what you're doing is incorrect. First of all, let me tell you WHY we choose the reaction (at the anode) with the lower electrode potential. If let's the say electrode potential at the cathode is +1.1V and 2 possible products at the anode have potentials...

    Chemistry: Post your doubts here!

    It's not wrong. The ER reiterates the answer and we know for a fact that whenever a halide ion is present in the solution of an electrolyte (of a salt), the halogen gas is liberated at the anode. It's a rule. Perhaps we can identify the problem if you tell us which standard potentials you're...

    Chemistry p5 doubts

    I've attached a picture of the table with the values (see expression for how each one was calculated): The expression I've used is a simplified one where I do not include the conversion of cm3 to dm3 because the conversions eventually get cancelled. To give you a single example expt 1. for...

    A level Biology: Post your doubts here!

    Can anyone give me a clear, precise and legit definition of biodiversity? It's an oft-repeated question in paper 4 and I'm unsure how to frame it. The best I've come up with so far is: Biodiversity is the total number of species living, including the genetic diversity between the different...

    What minimum SAT 2 score is needed to get in NUST?

    Its my Plan B but since people seem to be quite well-aware, I'd like to know what specialty I can land a seat in. I have a 2330 on the subject tests (no math), 4 As in my AS (will do A2 this year) and will apply as an overseas candidate.

    I got in my SAT scores today. 2060 alhumdulillah. I'm applying as an overseas candidate... does anyone know if this is good enough? I know they require ATLEAST an 1800 but I was in Pakistan last week and had quite a detailed conversation with the guy at the admission office. He told me they keep...

    Hey everyone! Finals are closing in on us, study hard everyone! :D So I've been having this problem with a type of question on the paper 5 in Physics, related to uncertainties, so I was hoping someone here can assist me. Now I know that when we are finding the absolute uncertainties in...

    Distinctions 2013

    Heh. Now, now... there's no need to be sore; work harder next year. :p On a serious note though, they HAVE been announced. Why would any school tell their students any thing like that if they weren't sure? I'll try to get a picture of the list my school got tomorrow (try!). If your school is...

    Yes. I'm in Riyadh, Saudi Arabia. They have been announced here. I've so far heard of 3 students in my school achieving distinctions this time and a fourth one who has left the school. I think they're announced at the same time all over the world, so if you're expecting anything call up your...

    I was using a MBP when I took the screenshot. Fonts and webpage appearance are slightly different on MBPs, I think. But it's definitely original, I took it myself.

    getting high marks in sat 2 biology

    I would disagree with this. Neither AS or A2 is must. I think a good knowledge of biology from grade 8, 9 and 10 along with a good memory and the ability to grasp concepts just by reading should suffice. It's nothing too complex. My two cents.

    getting high marks in sat 2 biology

    I did my SAT Biology in October after my AS exams. It was fairly hard and I prepared from the Kaplan book. I got a 750. Good enough, but I had potential to do better. I also gave SAT Chem in the same sitting (studied from Barron's) and got an 800. I did Physics in Dec and studied for it for only...
