The ksp of agcl is 1.6 x 10-10. what is the solubility of agcl in 0.010 m fecl3? give your answer using scientific notation (1.2
bija089 [108]

Ksp of AgCl= 1.6×10⁻¹⁰

AgCl=Ag⁺ +Cl⁻

Ksp=[Ag⁺][Cl⁻]

Assume [Ag⁺]=[Cl⁻]=x

Ksp=x²

1.6×10⁻¹⁰=x²

x=0.000012

In FeCl₃:

FeCl₃------>Fe⁺³+ 3Cl⁻

as there is 0.010 M FeCl₃

So there will be ,

[Cl⁻]= 0.030

So

[Ag⁺]=Ksp/[Cl⁻]

=1.6×10⁻¹⁰/0.030

=5.3×10⁻⁹

so solubility of AgCl in FeCl₃ will be 5.3×10⁻⁹.

A 25.0 L gas cylinder at 32.0 is filled with 2.33 moles of carbon dioxide and 4.66 moles of nitrogen. Calculate the total pressu
Phantasy [73]

Answer:

P= 7.01 atm

P(CO₂)= 2.34 atm

Explanation:

Step 1: Convert the temperature to Kelvin

We will use the following expression.

K = °C + 273.15

K = 32.0°C + 273.15 = 305.2 K

Step 2: Calculate the total number of moles of the mixture

We will use the following expression.

n = nCO₂ + nN₂ = 2.33 mol + 4.66 mol = 6.99 mol

Step 3: Calculate the total pressure of the mixture

We will use the ideal gas equation.

P × V = n × R × T

P = n × R × T / V

P = 6.99 mol × 0.0821 atm.L/mol.K × 305.2 K / 25.0 L

P= 7.01 atm

Step 4: Calculate the partial pressure of carbon dioxide

We will use the ideal gas equation.

P(CO₂) × V = nCO₂ × R × T

P(CO₂) = nCO₂ × R × T / V

P(CO₂) = 2.33 mol × 0.0821 atm.L/mol.K × 305.2 K / 25.0 L

P(CO₂)= 2.34 atm
