I have doubt in only two questions. MCQ 4 (the kettle one) and MCQ 33 (the one in which u had to compare in 2 fertilizers the amount of nitrogen by moles and mass)

Still have a doubt in MCQ33 .. i m beginning to conclude that i did it wrong that slag one also went wrong

 

[Haris Sal11]

its a polar compound which conducts in aq state

Liquid means it contains H+ and OH-. It does conduct, I know.
