Question

in the reaction 3H2+ N2_______NH3 what coefficient should be placed in front of NH3 to balance the reaction.
A.1
B2
C.3
D. no coefficient is needed

Answer 1

Answer:

  2

Explanation:

There are 3·2 = 6 H and 1·2 = 2 N on the left. These are combined as 1N+3H on the right, so the sum needs to be multiplied by 2 to make the numbers match. (6H+2N) = 2(3H+N)

  3H₂ + N₂ ⇔ 2NH₃
