Nitrogen gas (N2) and hydrogen gas (H2) react to produce ammonia (NH3). If we have 2 mol of N2, how many moles of NH3 will be produced?
1 mol NH3
2 mol NH3
3 mol NH3
4 mol NH3

I believe it would be 2

Explanation:

if there are 2 nitrogen molecules then there would have to be 2 hydrogen molecules but this could be completely wrong

if this happens to be right, ur welcome :3 here's a Jay Jay pic for u cuz why not

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
