    Chemistry: Post your doubts here!

    sure..in increasing order of strength: Temporary dipole-dipole interactions(more commonly known as the dispersion forces), dipole-dipole interaction and the strongest hydrogen bonding. No dipole-dipole forces are 1 of the van der waals forces, completely different thatn Ionic bonds. You want me...

    Chemistry: Post your doubts here!

    In Mg the outermost electron is in 3S while in Al it is in 3P. 3P is further away from the nucleus hence the ionization energy of Mg is higher

    Chemistry: Post your doubts here!

    Yes thats right. Chlorine is not electronegative enough to pull the electrons all the way to itself because of the high charge density of aluminium but fllourine is capable. so yea F takes them completely.

    Chemistry: Post your doubts here!

    The aluminium ion is very small and is pack with 3+ charges-the charge density is therefore very high. so the electrons are dragged over to the aluminium ion. However since the chlorine is more electronegative than aluminium, it pulls the electrons towards itself such that the bond formed is...

    Economics P12 june 2012 ANSWERS...!!!

    I chose A as well but many people are saying it was C because even if innovation decreases to zero, it means that technological advancement is not taking place. But the technology is already there so it cannot possibly cause it to shift inwards.

    Economics P12 june 2012 ANSWERS...!!!

    No the answer was D. Hyperinflation is when the inflation rate is at least 100 percent..Anyways there was always inflation! so D cudnt possibly be wrong!..

    AS MECHANICS p42 is (!!!!!!!!!!!!!!!!!!!!!!!!!), discuss after 24H

    Yea thats right!..I got it wrong though..didnt take both the resistances into account so i got acceleration as 9.2 and hence got the tension wrong..i hope the examiner gives me ECF

    I think 30!

    AS MECHANICS p42 is (!!!!!!!!!!!!!!!!!!!!!!!!!), discuss after 24H

    This was one horrific mechanics paper..GT is bound to be very low. Im guessing 30..GT for nov 2011 was 33 and that paper was much more easier than this years'.

    AS MECHANICS p42 is (!!!!!!!!!!!!!!!!!!!!!!!!!), discuss after 24H

    No they dont cut marks for not drawing graphs on a graph paper..in my centre almost no one used graph paper. Besides the question said sketch a graph so its perfectly alright if you did that on ur answer sheet

    M-1

    Will depend on the grade threshold. For november 2011 it was 92 out of 125. So the grade threshold for A should be 90 for you to get an A
