    ethanedioic acid is furhter oxidised to Co2 and H2o.no?

    thats why we use water to absorb high or low heat as the distance is changed and temp is kept constant

    it is to keep the heat from source constant (to standardise this variable)

    I dont think this is the case. It would still show optical isomerism.

    How do we come to know where to place the Cl and NH3? Cant there be any other arrangement apart from these?

    with 180 degree phase differene. it was mentioned in a mark scheme of a previous paper

    just 1

    then I guess that would be correct

    I think there wasnt much differemce although I made a few silly mistakes. What about you?

    The change could be say, 0-12= -12 or 0-(-12)=12 so change could be either -ve and +ve. no?

    IN the application booklet it is the range of frequencies occupied by a waveform. It would be the difference in max and min frequencies. As for the other you might lose a mark for not explaining why there was no temp change

    If we consider sign of B and put it in formula that we used before to prove the voltage wont we get a negative value of voltage? Are u sure your friends did it the right way?

    Idk but over there values of B are GREATER THAN Zero only. There arent any -ve values as were in our paper

    we had to explain it as well.
