What are the partial pressures of NH3 and H2S at equilibrium, that is, what are the values of PNH3 and PH2S, respectively?Enter
mylen [45]

Answer:

Ammonium bisulfide, NH4HS , forms ammonia, NH3 , and hydrogen sulfide, H2S , through the reaction NH4HS(s)⇄NH3(g)+H2S(g) This reaction has a Kp value of 0.120 at 25°C .

An empty 5.00-L flask is charged with 0.300 g of pure H2S(g) , at 25°C

Partial pressure of NH3 = 0.325 atm

Partial pressure of H2S  = 0.368 atm

Explanation:

Temperature = 25 °C = 298 K

Volume = 5 L

Mass of H2S = 0.30 g

Moles of H2S = 0.30 / 34.08

= 0.0088

Using PV = nRT

Initial pressure of H2S = 0.0088 * 0.0821 * 298 / 5

= 0.043 atm

Kp = 0.120

(a). NH4HS(s) ⇄ NH3(g) + H2S(g)

Initial - 0.0 0.043

Change - + x + x

Equilibrium - x 0.043 + x

Kp = P(NH3) * P(H2S)

0.120 = x (0.043 + x)

x = 0.325 atm

Hence, at equilibrium:

Partial pressure of NH3 = 0.325 atm

Partial pressure of H2S = 0.043 + 0.325 = 0.368 atm

A patient is given 200 mg of a drug with the formula: C32H34N6O10. How many mg of the drug is carbon?
Mice21 [21]

200 mg of C₃₂H₃₄N₆O₁₀ contains 116 mg of carbon.

To obtain the answer to the question, we'll begin by calculating the molar mass of C₃₂H₃₄N₆O₁₀. This can be obtained as follow:

Molar mass of C₃₂H₃₄N₆O₁₀ = (12×32) + (1×34) + (14×6) + (16×10)

= 384 + 34 + 84 + 160

<h3>= 662 g/mol </h3>

From the molar mass of C₃₂H₃₄N₆O₁₀, we can see that:

<h3>662 g of C₃₂H₃₄N₆O₁₀ contains 384 g of carbon. </h3>

Converting 662 g of C₃₂H₃₄N₆O₁₀ to mg, we have

1 g = 1000 mg

Therefore,

662 g = 662 × 1000

<h3>662 g of C₃₂H₃₄N₆O₁₀ = 662000 mg</h3>

Converting 384 g of carbon to mg, we have,

1 g = 1000 mg

Therefore,

384 g = 384 × 1000

<h3>384 g of carbon = 384000 mg</h3>

Thus, we can say that:

662000 mg of C₃₂H₃₄N₆O₁₀ contains 384000 mg of carbon.

Finally, we shall determine the mass (in mg) of carbon in 200 mg of C₃₂H₃₄N₆O₁₀. This can be obtained as follow:

662000 mg of C₃₂H₃₄N₆O₁₀ contains 384000 mg of carbon.

Therefore, 200 mg of C₃₂H₃₄N₆O₁₀ will contain = \frac{200 * 384000}{662000} = 116 mg of carbon.

Thus, we can conclude that 200 mg of C₃₂H₃₄N₆O₁₀ contains 116 mg of carbon.
