Understanding the Chemical Reaction

Ammonia, NH$_3$, is a chemical compound that plays a crucial role in various industrial and household applications. It is widely used as a fertilizer and in many household cleaners due to its unique properties. In this article, we will delve into the chemical reaction that produces ammonia and calculate the number of moles of ammonia produced when 6 mol of hydrogen gas react with an excess of nitrogen gas.

The Chemical Equation

The chemical equation for the production of ammonia is:

N$_2$(g) + 3H$_2$(g) → 2NH$_3$(g)

In this equation, nitrogen gas (N$_2$) reacts with hydrogen gas (H$_2$) to produce ammonia (NH$_3$). The balanced equation shows that 1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to produce 2 moles of ammonia.

Calculating the Number of Moles of Ammonia Produced

To calculate the number of moles of ammonia produced, we need to know the number of moles of hydrogen gas that react with an excess of nitrogen gas. According to the balanced equation, 3 moles of hydrogen gas are required to produce 2 moles of ammonia.

Given that 6 mol of hydrogen gas react with an excess of nitrogen gas, we can calculate the number of moles of ammonia produced as follows:

Let x be the number of moles of ammonia produced.

From the balanced equation, we know that 3 moles of hydrogen gas produce 2 moles of ammonia. Therefore, the ratio of hydrogen gas to ammonia is 3:2.

We can set up a proportion to relate the number of moles of hydrogen gas to the number of moles of ammonia produced:

3 mol H$_2$ / 2 mol NH$_3$ = 6 mol H$_2$ / x mol NH$_3$

Cross-multiplying, we get:

3x = 2(6)

Simplifying, we get:

3x = 12

Dividing both sides by 3, we get:

x = 4

Therefore, 4 mol of ammonia are produced when 6 mol of hydrogen gas react with an excess of nitrogen gas.

Conclusion

In conclusion, ammonia is a chemical compound that plays a crucial role in various industrial and household applications. The chemical reaction that produces ammonia is N$_2$(g) + 3H$_2$(g) → 2NH$_3$(g). By calculating the number of moles of ammonia produced when 6 mol of hydrogen gas react with an excess of nitrogen gas, we found that 4 mol of ammonia are produced.
