    BIO PRACTICAL 34

    I think we should all realize that Allah loves those who are Trustworthy and Honest, and who avoid doubtful matters and forbidden matters even if the entire community around them practices them. Allah ka Naam le kar cheating karna Ihsan (goodness) nahi hai. Allah ham sab ko tawbah ki tawfeeq...

    Chemistry Paper 22: Discussion and Grade Threshold

    Same here. It wasn't hard, actually. It was fairly simple once you understood it. That was the thing - understanding. The paper was unexpectedly tricky.

    Some biology practical doubts

    Hmm... do not set a microscope at high power immediately, even if they ask for you to look at high power. Set it up at low power first, find a clear image in sharp focus, then change it to high power. If the image loses clarity again, use the fine adjustment knob to find the clear image in sharp...

    Some biology practical doubts

    I think the water-bath in Centers is electricity-powered (electronic). I mean, my college became a Center of my city and the water-bath here is electronic. And I don't think we use a regular 'water-bath-in-a-beaker' thing in AS Levels, unless that's specifically the question. Anyways, for...

    Chemistry Paper 22: Discussion and Grade Threshold

    Based on how "well" the students at my school did the paper, I'm judging a GT of around 40-42.

    Some biology practical doubts

    1. I think the water-bath is already set at 80/90 degrees (if its electronic). That's enough; I don't think its ever at 100, because if it were, there would be no water there after a few minutes. o_o 2. 5 minutes. 3. Measure; the volume of biuret solution (or 5% potassium hydroxide) should be...

    AS Chemistry P2 Prep.

    Don't give out information about the paper; like how many questions there were or other things more important than that, before 24 hrs. o_o; But anyways, I screwed up in the first question; gonna probably lose 3-6 marks there, but Al-Hamdulillah the next ones went well; I expect full or only...

    ᴊυѕт ᴀ ғᴇω мᴀɢɪсᴀʟ ωᴏяᴅѕ

    Subhan Allahi wa bihamdihi, Subhan Allahil-Azeem. I love these forums already :) Subhan Allahi, al-Hamdulillahi, la ilaha il-Allahu, Allahu Akbar. And never forget: La hawla wa la quwwata illa biLlahil-Aliyyil-Azeem. Narrated Abu Musa (radhiAllahu Anhu): We were with the Prophet...

    Of the most ideal gas? CO2. I wrote that above. :cool:

    AS Chemistry P2 Prep.

    He is inert, so no. The rest are all non-polar; but CO2 should be the answer, as it has the largest mass, and therefore the largest strength of van der Waals' forces among all of the remaining gases. He = No. Its the closest to ideality. CH4 = More ideal than N2. N2 = More ideal than CO2. CO2...

    If its not under reflux, still, unless they say 'the product was distilled' or 'removed' before complete reaction or something like that, then its an aldehyde. If not, its a carboxylic acid.

    AS Chemistry P2 Prep.

    This one's a bit difficult... I dislike Equilibria. >_< From (b)(iv) we know that 0.04 of NaOH reacted with the ethanoic acid; NaOH is ROH in the table. As the mole ratio of CH3COOH and NaOH is the same, 0.04 mol of NaOH react with 0.04 mol of CH3COOH. This leaves behind 0.10 - 0.04 = 0.06...
