Heres the questions:
In part:
b) (i). why does Nitrogen make up most exhaust fumes? Never understand this!
c) (i). Is Gas II & its effect relevant & correct?
(ii) exam Answers says Gas I & Gas II removal reactions are not correct (balanced)
How else am i to balance it...either way works but is there a rule.
Theres always confusions with such reactions, so is there a rule that applies in all reactions?? How to know the real products that will form with reactants??
