Answer: 1.58\times 10^{-3}atm

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

               2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)       The expression for equilibrium constant for this reaction will be,

K_p=\frac{(p_{SO_3})^2}{(p_{SO_2})^2(p_{O_2})}

Now put all the given values in this expression, we get :

0.345=\frac{(p_{SO_3})^2}{(0.125)^2(0.470)}

p_{SO_3}=1.58\times 10^{-3}atm

Thus the equilibrium partial pressure of SO_3 in the mixture is 1.58\times 10^{-3}atm

a chemist makes of silver perchlorate working solution by adding distilled water to of a stock solution of silver perchlorate in
Elodia [21]

The concentration of the chemist's working solution is 6.718 mol/L.

Given,

The volume of silver perchlorate solution (V₁) = 790 ml.

The volume of distilled water added to the silver perchlorate(V₂) = 290ml.

The concentration of a stock solution of silver perchlorate (C₂) = 18.3 mol/L.

We have to find the concentration of the chemist's working solution (C₁).

As we know,

V₁C₁ = V₂C₂

From the above formula, we get,

C₁ = V₂C₂/V₁

C₁ = 290 × 18.3/ 790

C₁ = 6.718 mol/L

The concentration of the working solution = 6.718 mol/L

Hence, the concentration of the chemist's working solution is 6.718 mol/L.

Propane has a normal boiling point of -42.04 °C and a heat of vaporization of 24.54 kJ/mole. What is the vapor pressure of propa
Mademuasel [1]

Answer : The vapor pressure of propane at 25.0^oC is 17.73 atm.

Explanation :

The Clausius- Clapeyron equation is :

\ln (\frac{P_2}{P_1})=\frac{\Delta H_{vap}}{R}\times (\frac{1}{T_1}-\frac{1}{T_2})

where,

P_1 = vapor pressure of propane at 25.0^oC = ?

P_2 = vapor pressure of propane at normal boiling point = 1 atm

T_1 = temperature of propane = 25.0^oC=273+25.0=298.0K

T_2 = normal boiling point of propane = -42.04^oC=230.96K

\Delta H_{vap} = heat of vaporization = 24.54 kJ/mole = 24540 J/mole

R = universal constant = 8.314 J/K.mole

Now put all the given values in the above formula, we get:

\ln (\frac{1atm}{P_1})=\frac{24540J/mole}{8.314J/K.mole}\times (\frac{1}{298.0K}-\frac{1}{230.96K})

P_1=17.73atm

Hence, the vapor pressure of propane at 25.0^oC is 17.73 atm.

A water solution is found to have a molar oh- concentration of 3.2 x 10-5. the solution would be classified as :_______.
Anuta_ua [19.1K]

A water solution is found to have a molar oh- concentration of 3.2 x 10-5. the solution would be classified as neutral.

The concentration of hydroxide ions (OH-) is measured by pOH. It is a way of expressing how alkaline a solution is. At 25 degrees Celsius, aqueous solutions with pOH values of 7 or less are neutral, whereas those with pOH values of 7 or more are acidic. The hydrogen ion potential is known as pH. The potential of hydroxide ions is known as pOH. 2. It is a scale used to estimate the hydrogen ion (H+) concentration in the solution. The hydroxide ion (OH-) concentration of the solution is measured using this scale.

pH + pOH = 14

 pOH = 3.2x 10-5

[OH-] = 10^(-pOH) =10^(- 3.2x 10-5)

= 0.99
