Given the reaction: n2(g) + 3h2(g) 2nh3(g) what is the mole-to-mole ratio between nitrogen gas and hydrogen gas? (1) 1: 2 (3) 2: 2 (2) 1: 3 (4) 2: 3

The balanced equation for the formation of ammonia is as follows;
N₂ + 3H₂ ---> 2NH₃
stoichiometry is the molar ratio of components in a reaction.
Stoichiometry could be determined using the coefficients of the compounds in balanced reactions.
coefficient of N₂ - 1
coefficient of H₂ - 3
molar ratio of N₂ to H₂ is 1:3
(2) 1:3

Cis the answer ur welcome if i get it wrong u don't have to me
