Q2. e)Carbon disulphide reacts with nitrogen monoxide, NO, to form a yellow solid and two
colourless gases which are produced in a 1:1 molar ratio.
Deduce the identity of each gas and write a balanced equation for the reaction.
gases ........................................................ and ...............................................................
equation ..................................................................................................................... [3].
The answer for equation is :CS2 + 2NO → 2S + CO2 + N2.
why do we write S for sulphur why not S8. Will I be penalized if i write
4CS2 + 8NO → S8 + 4CO2 + 4N2

Hi rosh2004
I would not write S8 in an equation like that. I agree that it is an allotropic form of sulphur but it is still classed as an element and hence S is the accepted form.
As for would you get it wrong, I can't be sure. Your balancing is just a multiple of the final answer so if it was MY test I would give you benefit of the doubt. Hope that helps a bit.

Yes, there are lots allotropes of sulfur! The Wikipedia (which is very hard reading) lists them all. https://en.wikipedia.org/wiki/Allotropes_of_sulfur
This website is a bit of an easier read: http://nobel.scas.bcit.ca/resource/ptable/sallo.htm
Hope that helps!
