Question

Consider the equation below. N2 + 3H2 -> 2NH3 What is the mole ratio of hydrogen to ammonia?

Answer 1

Answer:

3:2

Explanation:

Answer 2

The answer is: C. 3 : 2.

Balanced chemical reaction: 3H₂ + N₂ → 2NH₃.

From chemical reaction: n(H₂) : n(NH₃) = 3 : 2.

Coefficients with the lowest ratio indicate the relative amounts of substances in a reaction.

Coefficient in fron of hydrogen is 3 and coefficient in fron ammonia is 2.

Coefficients are important to prove the law of conservation of mass.
