Understanding the Chemical Reaction

The given chemical reaction is:

${ N_2 + 3 H_2 \rightarrow 2 NH_3 }$

This reaction involves the combination of nitrogen gas (N2) and hydrogen gas (H2) to produce ammonia (NH3). The reaction is a classic example of a synthesis reaction, where two or more substances combine to form a new compound.

Calculating Moles of NH3 Produced

To calculate the moles of NH3 produced from the given reaction, we need to use the mole ratio between N2 and NH3. From the balanced equation, we can see that 1 mole of N2 produces 2 moles of NH3.

Calculating Moles of NH3 Produced from 5 mol N2

Given that we start with 5 mol of N2, we can calculate the moles of NH3 produced as follows:

${ 5 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 10 \, \text{mol} \, NH_3 }$

Therefore, 5 mol of N2 will produce 10 mol of NH3.

Calculating Moles of NH3 Produced from 10 mol N2

To calculate the moles of NH3 produced from 10 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 10 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 20 \, \text{mol} \, NH_3 }$

Therefore, 10 mol of N2 will produce 20 mol of NH3.

Calculating Moles of NH3 Produced from 15 mol N2

To calculate the moles of NH3 produced from 15 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 15 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 30 \, \text{mol} \, NH_3 }$

Therefore, 15 mol of N2 will produce 30 mol of NH3.

Calculating Moles of NH3 Produced from 20 mol N2

To calculate the moles of NH3 produced from 20 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 20 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 40 \, \text{mol} \, NH_3 }$

Therefore, 20 mol of N2 will produce 40 mol of NH3.

Calculating Moles of NH3 Produced from 25 mol N2

To calculate the moles of NH3 produced from 25 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 25 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 50 \, \text{mol} \, NH_3 }$

Therefore, 25 mol of N2 will produce 50 mol of NH3.

Calculating Moles of NH3 Produced from 30 mol N2

To calculate the moles of NH3 produced from 30 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 30 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 60 \, \text{mol} \, NH_3 }$

Therefore, 30 mol of N2 will produce 60 mol of NH3.

Calculating Moles of NH3 Produced from 35 mol N2

To calculate the moles of NH3 produced from 35 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 35 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 70 \, \text{mol} \, NH_3 }$

Therefore, 35 mol of N2 will produce 70 mol of NH3.

Calculating Moles of NH3 Produced from 40 mol N2

To calculate the moles of NH3 produced from 40 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 40 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 80 \, \text{mol} \, NH_3 }$

Therefore, 40 mol of N2 will produce 80 mol of NH3.

Calculating Moles of NH3 Produced from 45 mol N2

To calculate the moles of NH3 produced from 45 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 45 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 90 \, \text{mol} \, NH_3 }$

Therefore, 45 mol of N2 will produce 90 mol of NH3.

Calculating Moles of NH3 Produced from 50 mol N2

To calculate the moles of NH3 produced from 50 mol of N2, we can simply multiply the number of moles of N2 by the mole ratio:

${ 50 \, \text{mol} \, N_2 \times \frac{2 \, \text{mol} \, NH_3}{1 \, \text{mol} \, N_2} = 100 \, \text{mol} \, NH_3 }$

Therefore, 50 mol of N2 will produce 100 mol of NH3.

Conclusion

In conclusion, we have calculated the moles of NH3 produced from different amounts of N2 using the mole ratio from the balanced equation. The results show that the moles of NH3 produced are directly proportional to the moles of N2 used. This demonstrates the importance of understanding the mole ratio in chemical reactions and how it can be used to calculate the amount of product produced.
