Chemical bonds?

Submitted by Anonymous on 22 October 2004 - 12:51pm.

Hi All,

I have just started to get interested in chemistry and need a little help.
I am trying to figure out chemical bonds.

So here goes:

I have 1 nitrogen molecule and 2 oxygen molecules if they combine will they give me 2 or 1 nitrogen dioxide molecule/s?

This is what is confusing me because both molecules are two atoms each? What i mean is because each element has two atoms to make it up, eg. oxygen is two atoms of oxygen and nitrogen is two atoms of nitrogen? So I have 6 atoms but only 3 elements.

So is it 1 or 2 molecules I end up with?

Thanks everybody.

Steve

You are so confused that even your question is confusing lol

One thing to remember
chemical reactions never change the number of ATOMS - you can't destroy atoms or create new atoms using a chemical reaction.

So if you start off with 4 oxygen atoms and two nitrogen atoms,
they'll still be there at the end of the reaction -
they'll just be rearranged into different molecules.

*recalls back to Dalton's theories*

** atoms are not made or destroyed, only rearranged**

Think of it as moles not atoms.

N2 + 2O2 > 2NO2

You start with 3 molecules and end with 2 molecules, but the total number of atoms (6) remains constant.

And they combine in large numbers...

:shock:
