Hint: The stoichiometry is one of the branches of chemistry which is used to determine relative quantities of the reactant and products which are consumed and produced within a given chemical reaction. Stoichiometry is related to the law of conservation.
Complete step by step answer:
The stoichiometry is derived from a Greek word “stoichen” which means element and “metron” means measure. So, stoichiometry deals with determining the amount of reactants and products which are consumed and produced within a given chemical reaction.
The stoichiometry is based on the principles of law of conservation of mass. The Law states that the matter can neither be created nor be destroyed. Therefore, the mass of each element present in the products side of the chemical reaction should be equal to the mass of each present in the reactants side.
To determine the stoichiometry of the reaction, first the chemical equation should be balanced. In the balanced chemical equation it is easy to determine the stoichiometric ratio between the number of moles of reactants and the products.
The reaction between nitrogen and hydrogen is shown below.
${N_2}(g) + 3{H_2}(g) \to 2N{H_3}(g)$
In this reaction, one mole of nitrogen reacts with three mole of hydrogen to form two mole of ammonia. Therefore the stoichiometry ratio also known as the molar ration of the chemical reaction is 1:3:2.
Here, one mole of nitrogen completely reacts with three mole of hydrogen, and all the reactant is consumed to form two mole of ammonia.
Note: The stoichiometry method can be used to determine the limiting reactant or the reagent and to calculate the amount of excess reactant which is left even after the reaction is completed.
