How many molecules of ammonia, hydrogen and nitrogen are in this equation?

3H (subscript 2) + N (subscript 2) ---> 2NH (subscript 3)

[ladyalex]

Is that the full question, Double93?

[Dogsbody2]

Do you understand what a molecule is? Try Googling it, then it becomes rather trivial.

[frugalfred]

2; 6; 2. (the gas ammonia is NHsubscipt 3)

I suggest you try te Dogsbody method; if you use the frugalfred answer you won't get many marks.

Does Avogadro make an appearance here somewhere?

Or have I totally forgotten, got confused about my chemistry lessons.
(Goodness knows I was confused enough about them when I had to sit through them.)

[bhg481]

No, Avogadro is dead Ladyalex, he won't be making an appearance here.

[ladyalex]

Actually that is a relief to me. I can now forget about him and his number after all these years.
Never liked him much, the umber was too big for me to think about clearly.

[ladyalex]

the number, not the umber...that's a river, innit?

[bhg481]

Hard luck ladyalex, Avogadro might be dead but his number lives on. It is big though, isn't it?

[Dogsbody2]

Memo for Frugalfred: I must remember to find out what the difference between an atom and a molecule is. Lest I make a fool of myself in class.

[ladyalex]

Oh no...just when I thought it was safe to forget about him and his number....all those zeros

[Double93]

I know a molecule is when two or more atoms form chemical bonds with each other.

Would i be right in saying:
2 Nitrogen molecules
3 Hydrogen molecules
2 Ammonia molecules?

[ladyalex]

Did he mean atoms???
I could have answered that....

[bhg481]

No

[Double93]

I mean 1 nitrogen!

[ladyalex]

Is that "no" for me, for Double 93 or for us both?

[bhg481]

My "no" was for Double93 ladyalex - he's got it right now. Sorry for any confusion.

[Double93]

Thank you :)

[ladyalex]

Hurrah!

Well done, Double93...it's always better when you get there on your own.

[bhg481]

No problem Double93. I'm always happy to point people in the right direction to get their homework right but doing it for them doesn't teach them anything. Dogsbody clearly thinks like I do.
