When 15.0 g of fluorite (CaF₂) reacts with excess sulfuric acid, hydrogen fluoride gas is collected at 744 torr and 25.5°C. Soli

d calcium sulfate is the other product. What gas temperature is required to store the gas in an 8.63-L container at 875 torr?

The reaction equation is:  CaF₂ + H₂SO₄ → 2HF + CaSO₄

The molar ratio between fluorite and hydrogen fluoride is 1 : 1.

The moles of fluorite supplied are:

Moles = 15 / 78.07                            Moles = 0.200

The moles of hydrogen fluoride produced will be 0.2.Now, we may use the ideal gas equation to determine the temperature:

PV = nRT                                            T = PV/nR

T = (875 * 8.63) / (0.2 * 62.36)

T = 605.45K

The temperature will be 331.85 °C  which is  required to store the gas in an 8.63-L container at 875 torr.

24. The air in a small 250 cm birthday balloon is at a pressure of 760 torr. A boy sits on it at
kvv77 [185]

Answer:

1.14atm

Explanation:

Given parameters:

V1 = 250cm³ ;

              1000cm³ = 1dm³;  so this is 0.25dm³

P1  = 760torr

            760torr  = 1atm

       

V2  = 220cm³ ; 0.22dm³

Unknown:

New pressure = ?

Solution:

To solve this problem, we apply Boyle's law and we use the expression below:

       P1 V1 = P2V2

The unknown is P2;

            1 x 0.25  = P2 x 0.22

                 P2  = 1.14atm

How many moles of KBr will be produced from 10.51 moles of BaBr2?
gregori [183]

Answer:

21.02moles of KBr

Explanation:

Parameters given:

Number of moles BaBr₂ = 10.51moles

Complete reaction equation:

           BaBr₂ + K₂SO₄ → KBr + BaSO₄

Upon inspecting the given equation, we find out that the atoms are not balanced on both sides of the equation:

        The balanced equation is:

           BaBr₂ + K₂SO₄ → 2KBr + BaSO₄

From the equation:

     1 mole of BaBr₂ produces 2 moles of KBr

∴   10.51 moles of BaBr₂ will yield (2 x 10.51) moles = 21.02moles of KBr
