if they say test for 2 gases most like youre heating a nitrate,and if u see a brown gas then that confirms it so then you say colourless gas produced that relights a glowing splint (o2) and an orange brown gas ( No2). if the substance has NH4, then u just say colourless gas evolved which turns damp red litmus paper blue (NH3).

Also you should know which reagent you are adding for e.g Zn powder and NaOH with the suspected soln- indicates testing for NH3 gas.
