Is this equation correct?

  1. May 5, 2005 #1
    2NH3(s) + 3Cl2(g) -> N2(g) + 6HCl(g)

    What should the state of NH3 be?

    NH3(s) ? What temperature are you working at ?

    Yeah, my thought was that he was talking about NH3(aq) (which is NH4OH), not the solid. Which of course produces (with Cl2(g)) NCl3 a moderate explosive. Hey haven't we all played with NI3 .... the stories I could tell ;)

    the equation was given to us like 2NH3(s) + 3Cl2(g) -> N2(g) + 6HCl(g) I'm not sure about the temperature though. And it also said that with extra Cl2 you get the equation like Cl2(g)+NH3(g) -> NCl3(g) + HCl(g)
    I suppose the state of NH3 in the first equation must be gas. The teacher must have misprinted it!

    Close but one of the products from the gas phase reaction is NH4Cl(s).

    but I thought that you get NH4Cl(s) when you use extra NH3

    Another hint: H2(g).
