  • Hi, I was just wondering, what molar was the nitric acid did you use?

  • @supermanschick95 12M, i think. 

  • I know about as much about chemistry that you (assuming) do about bull farming, but i have a questrion:

    Isn't NO2 laughing gas?

  • @holycrapapie NO, oh hell NO. Laughing gas is N2O, very different

  • Question! if you were to put the copper metal into the nitric acid at the temperature your freezer was, could it evolve N2O4 instead of 2NO2

  • um yeah posably, but NO2 would be made from the N2O4 beacues the reaction would heat up and the N2O4 would decompose.

    Yes, quite right. You certainly wouldn't be laughing after a dose of NO2.

  • hi, i am doing an expierament in school and i need to know step my step what i need and how to make it however, it cant be a video. can you tell me how and what i need to do to create the nitrogen dioxide by steps?

  • @TheNeilNeil Nitrogen Dioxide is actually used in some cases as a protein indicator. If you happen to get some on your fingers, it will indicate the protein present by turning them a yellow-ish brown color. Unfortunately, it doesn't wash off. It wears off, with your dead skin cells. You'll just have to wait until your skin cells shed.

  • @AlchemicalGarden NO... NO... I c wut u did thar.

  • Were doing this lab in honors chem and that gas smelled so bad....

  • @holycrapapie NO2 will kill you

    N2O is laughing gas and that is the harmless stuff as long as you dont use so much to kill yourself
