Introduction

Chemical equations are a fundamental concept in chemistry, allowing us to understand and predict the reactions between different substances. The equation provided, ${ \text{Sn} + 2 \text{HF} \rightarrow \text{SnF}_2 + \text{H}_2 }$, represents the reaction between tin (Sn) and hydrogen fluoride (HF). In this article, we will focus on the stoichiometry of this reaction, specifically determining the number of moles of Sn required to react with a given amount of HF.

Understanding the Chemical Equation

The given chemical equation is a balanced equation, meaning that the number of atoms of each element is the same on both the reactant and product sides. The equation shows that one mole of Sn reacts with two moles of HF to produce one mole of SnF2 and one mole of H2.

Stoichiometry of the Reaction

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. In this case, we are interested in determining the number of moles of Sn required to react with a given amount of HF.

Calculating the Number of Moles of Sn

To calculate the number of moles of Sn required, we need to know the number of moles of HF present. Let's assume we have a certain amount of HF, and we want to determine the number of moles of Sn required to react with it.

The molar mass of HF is given as $20.01 \, \text{g/mol}$. If we have a certain mass of HF, we can calculate the number of moles of HF present using the formula:

$$\text{moles of HF} = \frac{\text{mass of HF}}{\text{molar mass of HF}}$$

For example, if we have $40.02 \, \text{g}$ of HF, we can calculate the number of moles of HF as follows:

$$\text{moles of HF} = \frac{40.02 \, \text{g}}{20.01 \, \text{g/mol}} = 2 \, \text{mol}$$

Since the balanced equation shows that one mole of Sn reacts with two moles of HF, we can calculate the number of moles of Sn required to react with two moles of HF as follows:

$$\text{moles of Sn} = \frac{\text{moles of HF}}{2} = \frac{2 \, \text{mol}}{2} = 1 \, \text{mol}$$

Therefore, one mole of Sn is required to react with two moles of HF.

Conclusion

In conclusion, the chemical equation between tin (Sn) and hydrogen fluoride (HF) is a balanced equation, showing that one mole of Sn reacts with two moles of HF to produce one mole of SnF2 and one mole of H2. By understanding the stoichiometry of this reaction, we can calculate the number of moles of Sn required to react with a given amount of HF. In this article, we have shown that one mole of Sn is required to react with two moles of HF.

A7: The molar mass of H2 is $2.02 \, \text{g/mol}$.

Q8: Can you provide an example of how to calculate the number of moles of Sn required to react with a given amount of HF?

A8: Let's say we have $40.02 \, \text{g}$ of HF. We can calculate the number of moles of HF as follows:

$$\text{moles of HF} = \frac{\text{mass of HF}}{\text{molar mass of HF}} = \frac{40.02 \, \text{g}}{20.01 \, \text{g/mol}} = 2 \, \text{mol}$$

Since the balanced equation shows that one mole of Sn reacts with two moles of HF, we can calculate the number of moles of Sn required to react with two moles of HF as follows:

$$\text{moles of Sn} = \frac{\text{moles of HF}}{2} = \frac{2 \, \text{mol}}{2} = 1 \, \text{mol}$$

Therefore, one mole of Sn is required to react with two moles of HF.

Q9: Can you provide an example of how to calculate the number of moles of HF required to react with a given amount of Sn?

A9: Let's say we have $118.71 \, \text{g}$ of Sn. We can calculate the number of moles of Sn as follows:

$$\text{moles of Sn} = \frac{\text{mass of Sn}}{\text{molar mass of Sn}} = \frac{118.71 \, \text{g}}{118.71 \, \text{g/mol}} = 1 \, \text{mol}$$

Since the balanced equation shows that one mole of Sn reacts with two moles of HF, we can calculate the number of moles of HF required to react with one mole of Sn as follows:

$$\text{moles of HF} = 2 \, \text{mol}$$

Therefore, two moles of HF are required to react with one mole of Sn.
