Most of the sulfur used in the United States is chemically synthesized from hydrogen sulfide gas recovered from natural gas well
Rom4ik [11]

Answer:

The rate at which sulfur dioxide is being produced is 0.90 kg/s.

Explanation:

Volume of oxygen gas consumed in second ,V= 994 L

Pressure of the gas = p

Temperature of the gas = T = 170°C= 170 + 273 K=443 K

Moles of oxygen gas consumed in a second = n

PV=nRT ( ideapl gas equation)

n=\frac{PV}{RT}=\frac{0.77 atm\times 994 L}{0.0821 atm L/mol K\times 443 K}

n = 21.044 mole

Moles of dioxygen gas consumed per second = 21.044 mol

2H_2S(g)+3O_2(g)\rightarrow 2SO_2(g)+2H_2O(g)   (Claus process)

According to reaction, 3 moles of dioxygen gives 2 moles of sulfur dioxide gas.Then 21.044 moles of dioxygen will give;

\frac{2}{3}\times 21.044 ol=14.029 mol of sulfur dioxide

Mass of 14.029 moles of sulfur dioxide gas;

14.029 mol × 64 g/mol = 897.86 g

897.86 g = 0.89786 kg ≈ 0.90 kg

Mass of sulfur dioxide produced per second = 0.90 kg

The rate at which sulfur dioxide is being produced is 0.90 kg/s.

How many moles of nitrogen gas are in a flask with a volume of 0.25 L at a pressure of 2.96 atm and a temperature of 300 K
aniked [119]

<u>Answer:</u> The number of moles of nitrogen gas is 0.030 moles

<u>Explanation:</u>

To calculate the number of moles of nitrogen, we use the equation given by ideal gas which follows:

PV=nRT

where,

P = pressure of the nitrogen gas = 2.96 atm

V = Volume of the gas = 0.25 L

T = Temperature of the gas = 300 K

R = Gas constant = 0.0821\text{ L. atm }mol^{-1}K^{-1}

n = number of moles of nitrogen gas = ?

Putting values in above equation, we get:

2.96atm\times 0.25L=n\times 0.0821\text{ L. atm }mol^{-1}K^{-1}\times 300K\\\\n=\frac{2.96\times 0.25}{0.0821\times 300}=0.030mol

Hence, the number of moles of nitrogen gas is 0.030 moles

How many molecules of F2 react with 66.6 g NH3 ? (stoichiometry)
stiks02 [169]
<h3>Answer:</h3>

5.89 × 10^23 molecules of F₂

<h3>Explanation:</h3>

The equation for the reaction between fluorine (F₂) and ammonia (NH₃) is given by;

5F₂ + 2NH₃ → N₂F₄ + 6 HF

We are given 66.6 g NH₃

We are required to determine the number of fluorine molecules

<h3>Step 1: Moles of Ammonia </h3>

Moles = Mass ÷ Molar mass

Molar mass of ammonia = 17.031 g/mol

Moles of NH₃ = 66.6 g ÷ 17.031 g/mol

                      = 3.911 moles

<h3>Step 2: Moles of Fluorine </h3>

From the equation 5 moles of Fluorine reacts with 2 moles of ammonia

Therefore,

Moles of fluorine = Moles of Ammonia × 5/2

                            = 3.911 moles × 5/2

                           = 9.778 moles

<h3>Step 3: Number of molecules of fluorine </h3>

We know that 1 mole of a compound contains number of molecules equivalent to the Avogadro's number, 6.022 × 10^23 molecules

Therefore;

1 mole of F₂ = 6.022 × 10^23 molecules

Thus,

9.778 moles of F₂ = 9.778 moles × 6.022 × 10^23 molecules/mole

                              = 5.89 × 10^23 molecules

Therefore, the number of fluorine molecules needed is 5.89 × 10^23 molecules

What is the volume of an 2.3 m solution with 212 grams of calcium chloride (cacl2) dissolved in it?
ira [324]

830 mL

The volume of an 2.3 m solution with 212 grams of calcium chloride (cacl2) dissolved is 830 mL.

The solution has a concentration of 2.3 mol/L.

<h3>a) Moles of CaCl2</h3>

Molar mass of CaCl2 = 110.98 g/mol

Moles of CaCl2 = 212 g CaCl2 x (1 mol CaCl2/110.98 g CaCl2)

= 1.910 mol CaCl2

<h3>b) Volume of solution</h3>

V = 1.910 mol CaCl2 x (1 L solution/2.3 mol CaCl2) = 0.83 L solution

= 830 mL solution

<h3>How much CaCl2 is there in the solution by molarity?</h3>
  • The number of moles is 0.125 x 2 = 0.25 mol since the molarity is 2.0M.
  • To get the answer of 27.745 g, simply multiply this by the molar mass of calcium chloride, which is 110.98 g/mol.
