As far as balancing problems go, this one is pretty simple, so you likely need more than the correct coefficients (and 1,1,2 is not correct) for this particular problem to know that you'll be able to solve others on your own. Balancing equations is merely making sure that you have the same ingredients when they're in different forms on either side of the arrow. On this one, I'd start by recognizing that you have 2 reactant Nitrogen atoms, so try a coefficient of 2 on the NH3. Then you can count the H atoms on your product side; it'll be 6, 3H2's will balance that.
These come pretty easily with practice, so I'd suggest getting some practice before your next quiz or exam.

Your question doesn't really make sense because in a chemical equation one or more elements/compounds have to yield some other elements/compounds. The yield sign is when you have and arrow pointing rightward, separating the left and right sides of the equation. However in your situation if some coefficient of N2+ some coefficient of H2 yields some coefficient of NH3 then the answer would be D. You would need 1N2 on the left side of the equation and 3H2 to balance the 2NH3 on the right side of the equation. These coefficients would give you 2N and 3 x H2 which equals 6H on the left side and 2x 1N equaling 2N on the right side and 3 x H2 which also equals 6H. Therefore each side is equal and the equation is balanced.

Well if this question is still open I'll bet words like reactant and coefficient confuse you. So although the answer is correct you still might just be confused.
Notice N2 means two nitrogen's NH3 means that one nitrogen reacts with three hydrogen's
H2 means two Hydrogen's
To react with 2 Nitrogen's you need 2x3=6 Hydrogen's
Therefore 1N2 will react with 3H2 to give 2NH3
N2 + 3H2 =2NH3

its d.) 1,3,2
it stabilizes the nitrogen in both sides with 2 electrons, respectively, and the hydrogen at both sides with 6 electrons, respectively

d) : N2+ 3H2--->2NH3
ya!!!!!!
& "getmeout" is right about u'r question not making sence becasue there is no yeild sign but it's an understandable error.
