Introduction to SF6

The compound SF6, also known as sulfur hexafluoride, is a highly stable and non-toxic gas that has various applications in industries such as electrical, electronics, and medical. Its unique properties make it an essential component in many devices and systems. In this article, we will delve into the synthesis of SF6 and the requirements for producing a specific amount of this compound.

Synthesis of SF6

The synthesis of SF6 involves the reaction of sulfur (S8) with fluorine gas (F2). The balanced chemical equation for this reaction is:

S8(s) + 24 F2(g) → 8 SF6(g)

This equation indicates that 1 mole of sulfur reacts with 24 moles of fluorine to produce 8 moles of SF6.

Requirements for Producing SF6

To determine the requirements for producing a specific amount of SF6, we need to analyze the balanced chemical equation. If we need to produce 2.50 moles of SF6, we can use the mole ratio from the balanced equation to calculate the amount of sulfur and fluorine required.

Calculating the Amount of Sulfur Required

From the balanced equation, we can see that 1 mole of sulfur produces 8 moles of SF6. To produce 2.50 moles of SF6, we need to calculate the amount of sulfur required.

Let's use the mole ratio to set up a proportion:

1 mole S8 : 8 moles SF6 = x moles S8 : 2.50 moles SF6

To solve for x, we can cross-multiply:

1 × 2.50 = 8x 2.50 = 8x x = 2.50 ÷ 8 x = 0.3125 moles S8

Therefore, we need 0.3125 moles of sulfur to produce 2.50 moles of SF6.

Calculating the Amount of Fluorine Required

From the balanced equation, we can see that 24 moles of fluorine are required to produce 8 moles of SF6. To produce 2.50 moles of SF6, we need to calculate the amount of fluorine required.

Let's use the mole ratio to set up a proportion:

24 moles F2 : 8 moles SF6 = y moles F2 : 2.50 moles SF6

To solve for y, we can cross-multiply:

24 × 2.50 = 8y 60 = 8y y = 60 ÷ 8 y = 7.5 moles F2

Therefore, we need 7.5 moles of fluorine to produce 2.50 moles of SF6.

Conclusion

In conclusion, to produce 2.50 moles of SF6, we need 0.3125 moles of sulfur and 7.5 moles of fluorine. The balanced chemical equation provides the mole ratio required to produce the desired amount of SF6.
