Question

Which set of coefficients will balance this chemical equation? __N2(g) + __H2(g) → NH3(g)

Answer 1

Answer: N2 +3H2 -> 2NH3

Explanation: The Coefficient must be a whole number

you have two N but only use 1 so doubling the product is required

Then you need 6 H but only have 2 so put a 3 in front
