    6 d ii Since increasing the voltage increases the current (V = IR) Resistance also increases as voltage increases, in this case current is increasing non linearly , so resistance increases as well. I'm not actually sure why current increases non linearly but when that does happen , resistance...

    That makes sense. I did it but my answer is coming as +40. Mark scheme says -40, can you tell me where I went wrong? 4th term : 5C3 *(2x)^2 * (-1/x)^3 = 10 * 4x^2 *-1/x^3 = 40x^2 * -1/x^3 = x ( 40 *-1/x)

    If it's absolutely unreadable then, yes they won't. But if it's messy but readable they'll still read it, but you always wanna make your presentation nice for the examiners to have a better mood ;)

    D ii ) Propene because as you can see there's 3 C atoms.. and the structural formula is just a simple propene with 3 C atoms, 1 double bond , and 6 H atoms.. CH3—CH=CH2 D iii ) Landfill sites..forms methene, non bio -degradable burning...forms posinous or toxic gases There is no 3 C ii btw.

    yeah but i'm guessing due to the weak intermolecular forces its mp/bp is very low, i guess it's an exception to its triple covalent bonding. Still unsure

    I get how you find the area of the yellow part, but what do you do after that? I don't understand the last part : area of yellow=1/2*(11.2*x)=1.6 80-x = 7.7 What is x? And why are we finding the area of yellow again when we just found it..? I'm confused, please explain if you can, or someone...
