B). 4:2
Explanation:
Mole ratio is described as the ratio between the number of moles present in two compounds that are entailed in a chemical reaction. These ratios are employed as the factors of conversion among the products as well as reactants in various chemical problems.
The chemical equation for the given reaction between NH3(ammonia) and N2(nitrogen) would be as follows:
2 NH3(g) --> N2(g) + 3 H2(g)
Since two moles of ammonia are required to make one mole of nitrogen. Therefore, the ratio of ammonia to nitrogen would be 4:2 or 2:1. Hence, option B is the correct answer.
