    A really hard chemistry question that keeps kinda repeating

    Ah yes This question Sorta hard to explain, I have it in m inbox somewhere when someone else asked me. Here: Okay From the graph you can tell that 8cm^3 of Na3PO4 reacts with all 12 cm3 T's Nitrate therefore the ratio of volumes of T Nitrate: Na3PO4 is 12:8 =3:2 Since the concentration is...

    Complete this equation : Pb(NO3)2 + NaCl →

    That's true But why does it react anyway? Isn't Sodium Chloride stable? I mean I can easily complete the equation, but I don't get why it reacts.

    Actually yes :| I had this awesome .gif of a baby being fed a grapefruit then sorta freezing and falling back xD Then CaptainPlanet messaged me and told me it's against rules to have animated things in signature :|

    I know it has value, obviously, and since in our syllabus goodwill accounts aren't present that means we don't have to worry about it being in balance sheet ;)

    :P I love your signature So much. But unfortunately not allowed animated things in signatures (no idea why :|)

    I got exactly 1.5 too ;) But I wrote 1.50 :|

    I wrote measure the diameter of the cylinder, divide by two to find radius 'r' then place the cylinder such that the opposite edges are on 90+r and 90-r respectively. e.g. if cylinder has diameter 4cm, radius = 2cm and edges are on 92 and 88 so center is on 90 ;)

    Also as for mass of ruler, we could do a preliminary estimation Ruler would be 100cm long, perhaps 4cm wide and prolly 0.5cm thick This would give vol. of 200cm3 Density of wood tends to be ~0.5 (depending on type, anything between 0.3 to 1.2, but the ones more than 0.7 are less common) So the...

    Honestly? I have no idea. I wrote that ruler may not be perfectly rectangular or have gaps between end of measure to end of ruler, thus center won't be at 50cm, though I don't think that counts as a difficulty. My friend wrote that it may be hard to move mass without moving the ruler's position...

    Just remember guys, 1 mark in paper 6 is only 0.5%!

    Your first one is wrong. Bubbles would only escape if the student pushed in at an angle or too fast; and the question said he did it correctly and carefully. FOr first one I wrote, vol. of finger pushing in not taken into account and liquid may compress the gas in the tube when pushed

    LOL I deleted that comment, because it's mostly wrong XD I'm sleepy And that question is...something which doesn't have marriage rights in many states. *Cough* Intangible means it has no physical form, but that doesn't mean it doesn't have value? Let me ask my super-smart friend >.< I know it...

    I have questions too: a) How is goodwill treated on balance sheet - as a fixed asset? and: http://www.xtremepapers.com/papers/CIE/Cambridge%20IGCSE/Accounting%20(0452)/0452_s10_qp_13.pdf Why is the answer to 1(c) A? Shouldn't it be B?

    Chemistry Doubts: IGCSE Paper 3

    Check the link to the chemistry notes in my signature. There's an awesome chapter about reversible reactions. Not sure which page so you may have to search (Just use Control+F in your .pdf reader and search for the word 'reversible' or 'equilibrium')

    IGCSE Chemistry Revision Guide | According to syllabus

    How did you do in paper 1/3? Shouldn't worry too much, 10 marks in paper 5 ( if it's out of 40) is only 5% of total grade, and last year p3 was easier than this but grade threshold was 70-75%(EDIT: For an A* that is) so don't worry!
