    So how was chemistry P12 today?

    Was that the question? :/ I got 4 answers wrong so far and in p2, I got the whole of the last question wrong cause I forgot that hot conc kmno4 breaks the double bond, so if there's no ECF, I lost 12 marks in one question

    Can't tertiary alcohols be dehydrated?! The carbon would be able to firm a double bond with any if the three alkyl groups...no? All my answers are different from everyone else's here :/

    What question was that? The one which asked which of the following effects of burning hydrocarbons does not have a handful effect on the environment?

    It was D cause option 2 said that nh3 acts as a base but it doesn't cause the final product is Ag(NH3)2 and it hasn't accepted a proton

    According to the Internet hydrogen bonding does affect viscosity

    Ohh. Would it? It said that they had the same mr so I didn't think so :p

    Physics 12 GT

    In the past papers there was a similar question but it was initially placed in the middle of the space between the plates and it accelerated...but that didn't take the repulsive forces into consideration.

    Was the partial pressure of steam the same as CO's?

    I dunno about that either but I think you're right about na2o and sulfuric acid. Ugh I was hoping to get above 38 in p1 cause that's the only way I could balance my grade! I completely messed up the practical and p2 :(

    Physics 12 GT

    Just one question. When a positive particle accelerates in an electric field starting from the positive plate whivh is placed below the negative one, does it accelerate or decelerate? I mean initially the repulsive force will be quite large so wont it start from a higher speed?

    Didn't it say neutralization. Sodium oxide would form nahso4 and h20 and I couldn't get that but I did get na2hpo4 and h20 fir phosphoric acid and sodium oxide

    It was 0.1 mole if oxygen and 0.3 moles of the products each dont remember the answer tho

    I think it's cause the total kinetic energy remains the same at Y. The sand is dropped with some velocity too

    It was fine. I marked the first answer I got...didn't have time to wonder whether it as a trick question
