Which would produce greater number of moles of product: a certain amount of hydrogen gas reacting with oxygen gas to make water, or the same amount of hydrogen gas reacting with nitrogen gas to make ammonia? Why?

Write the two balanced equations and see.
2H2 + O2 ==> 2H2O
3H2 + N2 ==> 2NH3.
Use a convenient number of moles H2 to start (say 2 moles but you can pick any number as long as you use the same number for both equations). How much water will we get (in moles).
2 moles H2 x (2 moles H2O/2 moles H2) = 2 moles x (2/2) = 2 mole H2O.
You can do NH3 the same way and compare. Post your work if you get stuck.
