The balanced chemical equation (including phases) that describes the reaction between diatomic hydrogen gas and diatomic nitrogen gas:
Further explanation
Stochiometry in Chemistry learns about chemical reactions mainly emphasizing quantitative, such as calculations of volume, mass, number, which are related to the number of actions, molecules, elements, etc.
In chemical calculations, the reaction can be determined, the number of substances that can be expressed in units of mass, volume, mole, or determine a chemical formula, for example, the substance level or molecular formula of the hydrate.
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
In the reaction equation there are also manifestations of reagent substances namely gas (g), liquid (liquid / l), solid (solid / s) and solution (aqueous / aq).
The reaction that happens between hydrogen and the nitrogen
Hโ (g) + N (g) โNH3 (g) + heat
We balance the reaction coefficient by giving each compound a variable
aNโ + bHโ -> cNHโ
For example a = 1 then:
N: 2a -> c ---> 2 = c
H: 2b -> 3c ---> 2b = 3.2 ---> 2b = 6 -> b = 3
So
b = 3
c = 2
The equation becomes:
Nโ + 3Hโ -> 2NHโ
The process of making ammonia is known as the Haber-Bosch process. Hydrogen is obtained from the conversion of natural gas containing hydrocarbon compounds of propane or butane. This hydrogen is then reacted with nitrogen from free air to produce ammonia.
