    Mathematics: Post your doubts here!

    I would love a bit of explaination you said 'Now da function of tan has a period of 180° (π radians) meaning dat its value repeats after each 180° cycle. 0° ≤ x ≤ 180° 0° ≤ 2x ≤ 360° ' Was it not supposed to be used as 2x = 360 − 143.2 , 180 − 71.6

    As sitoon said: P1 > 32-34 mostly P2 > 48 &above But it also depends on number of other factors. Especially the marks curve or such in your area. If many people didn't score high marks or most of them have low marks then the curve will go down, i.e. you might need less marks to score an A in p1...

    Chemistry: Post your doubts here!

    Actually with out catalyst you need two steps to convert ally alcohol into propanal, while when you use catalyst they both oxidation and reduction happens. You won't be asked how but, but i guess ruthenium catalysis both reduction and oxidation so that's why you will get propanal, or else it...

    You can check the ms (Mark Scheme). The answer is both oxidation and reduction has occurred in one step. Allyl alcohol is converted into propanal in two steps with out Catalyst: The first step is reduction (Reduction is Gain of hydrogen, in this case two hydrogen is gained) from the figure...
