Question for the Chem-heads here! I'm helping my nephew balancing equations and I'm stuck.

Can N2 + H2 --> 2NH?

Answer sheet is showing that in order to balance this equation, I'll need to make it N2 + 2 H2 --> 2NH2. why? Is the other answer wrong?

(I can't make numbers turn into subscripts, so any number that comes after a letter is a subscript!)

Its been too many years but I get N2 + 3 H2 --> 2 NH3 for it to balance out in moles.

Yep. Pretty easy to recognize ammonia. IIRC... that was the initial way of making ammonia and ammonia compounds from the air, with the addition of electricity. Those compounds were then to be used as fertilizer and in explosives. The Muscle Shoals power plant was to be the source of the electricity and Henry Ford was the big investor, but Roosevelt got involved and...

anyway, there were other simpler and cheaper methods found to make ammonia, using natural gas.

Sorry for the side trip into history, but it is a fascinating part of it.
