Question for Pure chem paper 2011 o level.

SNSDJess

May i know whats the minimum mark you should be getting for this paper to consider for a A1?
For qn2d, if i never compare will i get 0? I only say that it will produce H2 at cathode and O2 at anode.
For qn 6c, can i talk about the molecular formula? hexene and cycloheptane have same molecular formula but they have different from hexane.?
And SiO2 can i name it Silicon(IV) oxide?

Please answer my question. Thank you for your hard work! ;D
