Introduction

Ammonia is a crucial chemical compound used in various industrial processes, including the production of fertilizers, plastics, and pharmaceuticals. The formation of ammonia involves a chemical reaction between nitrogen gas and hydrogen gas. In this article, we will explore the equation for ammonia formation and calculate the amount of ammonia produced when 56 g of nitrogen gas is used in the reaction.

The Equation for Ammonia Formation

The equation for ammonia formation is:

${3 H_2(g) + N_2(g) \rightarrow 2 NH_3(g)}$

This equation shows that 3 molecules of hydrogen gas react with 1 molecule of nitrogen gas to produce 2 molecules of ammonia gas.

Understanding the Reaction

To calculate the amount of ammonia produced, we need to understand the stoichiometry of the reaction. The balanced equation shows that 3 moles of hydrogen gas react with 1 mole of nitrogen gas to produce 2 moles of ammonia gas. This means that the ratio of hydrogen gas to nitrogen gas to ammonia gas is 3:1:2.

Calculating the Amount of Ammonia Produced

To calculate the amount of ammonia produced, we need to know the number of moles of nitrogen gas used in the reaction. We can calculate the number of moles of nitrogen gas using the formula:

${moles = \frac{mass}{molar\ mass}}$

The molar mass of nitrogen gas is 28 g/mol. Therefore, the number of moles of nitrogen gas used in the reaction is:

${moles = \frac{56\ g}{28\ g/mol} = 2\ mol}$

Since the ratio of nitrogen gas to ammonia gas is 1:2, the number of moles of ammonia gas produced is:

${moles = 2\ mol \times 2 = 4\ mol}$

Calculating the Mass of Ammonia Produced

To calculate the mass of ammonia produced, we need to know the molar mass of ammonia gas. The molar mass of ammonia gas is 17 g/mol. Therefore, the mass of ammonia produced is:

${mass = moles \times molar\ mass}$

${mass = 4\ mol \times 17\ g/mol = 68\ g}$

Conclusion

In conclusion, when 56 g of nitrogen gas is used in the reaction, 68 g of ammonia gas will be produced. This calculation is based on the stoichiometry of the reaction and the molar masses of the reactants and products.

Table: Molar Masses of Reactants and Products

Substance	Molar Mass (g/mol)
Nitrogen gas (N2)	28
Hydrogen gas (H2)	2
Ammonia gas (NH3)	17

Discussion

The calculation of the amount of ammonia produced is a classic example of stoichiometry in chemistry. The balanced equation shows the ratio of reactants to products, and the molar masses of the reactants and products are used to calculate the amount of product produced. This calculation is essential in understanding the chemical reaction and predicting the amount of product produced.

Limitations of the Calculation

The calculation assumes that the reaction is carried out under ideal conditions, with no losses or side reactions. In reality, the reaction may not be 100% efficient, and some of the reactants may be lost or converted to other products. Therefore, the actual amount of ammonia produced may be different from the calculated value.

Future Directions

The calculation of the amount of ammonia produced can be extended to more complex reactions and systems. For example, the calculation can be used to predict the amount of product produced in a multi-step reaction or in a reaction involving multiple reactants. Additionally, the calculation can be used to optimize the reaction conditions and maximize the yield of the product.
