Introduction

Chemical reactions are a fundamental aspect of chemistry, and understanding the equations that govern these reactions is crucial for predicting the outcomes of various chemical processes. One such reaction is the combination of lithium (Li) with nitrogen (N2) to produce lithium nitride (Li3N). This reaction is of significant interest in the field of chemistry, particularly in the study of inorganic compounds and their applications. In this article, we will delve into the equation that describes this reaction and explore how to calculate the number of moles of lithium nitride produced when a given amount of lithium is reacted with excess nitrogen gas.

The Equation of Lithium Reacting with Nitrogen

The equation that describes the reaction between lithium and nitrogen to produce lithium nitride is given as:

${ 6 \text{Li} + \text{N}_2 \rightarrow 2 \text{Li}_3\text{N} \}$

This equation indicates that six moles of lithium react with one mole of nitrogen gas to produce two moles of lithium nitride. The coefficients in the equation represent the number of moles of each substance involved in the reaction.

Understanding the Reaction

To understand the reaction, let's break it down step by step. Lithium is a highly reactive metal that readily loses one electron to form a positive ion (Li+). Nitrogen, on the other hand, is a diatomic molecule that consists of two nitrogen atoms bonded together. When lithium reacts with nitrogen, the lithium atoms lose their electrons to form positive ions, which then combine with the nitrogen atoms to form lithium nitride.

Calculating the Number of Moles of Lithium Nitride Produced

Now, let's consider the scenario where 12 moles of lithium are reacted with excess nitrogen gas. To calculate the number of moles of lithium nitride produced, we need to use the equation and the given amount of lithium.

From the equation, we can see that 6 moles of lithium react to produce 2 moles of lithium nitride. Therefore, the ratio of lithium to lithium nitride is 6:2 or 3:1. This means that for every 3 moles of lithium, 1 mole of lithium nitride is produced.

Given that 12 moles of lithium are reacted, we can calculate the number of moles of lithium nitride produced as follows:

Number of moles of lithium nitride = (Number of moles of lithium) / 3 = 12 / 3 = 4

Therefore, 4 moles of lithium nitride are produced when 12 moles of lithium are reacted with excess nitrogen gas.

Conclusion

In conclusion, the equation that describes the reaction between lithium and nitrogen to produce lithium nitride is a fundamental concept in chemistry. By understanding this equation and the reaction it describes, we can calculate the number of moles of lithium nitride produced when a given amount of lithium is reacted with excess nitrogen gas. This knowledge is essential for predicting the outcomes of various chemical processes and has significant implications in the field of chemistry.
