What is the mole ratio between hydrogen #("H"_2")# and ammonia #("NH"_3")# in the chemical equation #"N"_2 + "3H"_2##rarr##"2NH"_3"#?

Answer 1

#"3 H"_2": 2 NH"_3"#

#"N"_2 + "3H"_2##rarr##"2NH"_3"#

In a balanced equation, the coefficients are the number of moles of each substance. If no coefficient is written, then it is understood to be #1#.

There are 3 moles hydrogen gas and 2 moles ammonia in the balanced chemical equation. The mole ratio of the two substances is #"3 H"_2:"2 NH"_3"#. When using the mole ratio with stoichiometry questions, you should write the mole ratio as follows:

#(3"mol H"_2)/(2"mol NH"_3)# or #(2"mol NH"_3)/(3"mol H"_2)#

3:2

The coefficients of the molecules in the reaction equation are called "Moles." For example, the coefficient of ammonia in this equation is 2, and the coefficient of hydrogen is 3.

Thus, the hydrogen to ammonia ratio is 3:2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
