We can not dissolve 35 moles of potassium permanganate into 500 ml of water as it produces the solution with higher molarity than water have.

<h3>What is molarity?</h3>

Molarity of any solution is define as the number of moles of solute present in per liter of the solvent as:

M = n/V

The molarity of the solvent, water, is the highest for aqueous solutions and molarity of 1000g of pure water in 1 liter is 55.5M

Given that,

  • n = moles of potassium permanganate = 35 moles
  • V = Volume = 500 mL = 500 / 1000 = 0.5 L

On putting values, we get

M = 35/0.5 = 70M

Preparation of this solution is impossible.

Hence, KMnO₄ will not dissolve in the water as it produces solution with higher molarity than water.

Yes, we can dissolve 35 moles of KMnO₄ into 500 mL of water to give a molarity of 70 M

<h3>What is molarity? </h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the molarity </h3>
  • Mole of KMnO₄ = 35 moles  
  • Volume = 500 mL = 500 / 1000 = 0.5 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 35 / 0.5

Molarity = 70 M

At the equilibrium point in the decomposition of phosphorus pentachloride to chlorine and phosphorus trichloride, the following
Hitman42 [59]

Answer: K_{eq} for the reaction is 5.55

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,

                        PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)          

At eqm. conc.   (0.010) M     (0.15)  M   (0.37) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[Cl_2]\times [PCl_3]}{[PCl_5]}

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

K_c=\frac{(0.37)\times (0.15)}{(0.010)}

K_c=5.55

Thus the K_{eq} for the reaction is 5.55

¿Podría predecir con antelación si una disolución acuosa será buena conductora de la corriente eléctrica, sabiendo cuál es el so
Ne4ueva [31]

Answer:

Si.

Explicación:

Sí, podemos predecir si una solución acuosa será un buen conductor de corriente eléctrica si conocemos el soluto que se disuelve en ese líquido y su concentración o cantidad. Hay algunas sustancias que se ionizan cuando se agregan en un líquido como el agua. Debido a esta ionización, será un buen conductor de electricidad. Por ejemplo, la adición de una gran cantidad de cloruro de sodio en agua ioniza y hace que el agua sea un buen medio conductor de electricidad.

If you add more molecules but do not change the temperature or the pressure, what will happen to the system?
VladimirAG [237]

Answer:

the volume will increase

Explanation:

The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .

Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .

Since pressure  is also constant , it is volume which will be increased .

It can be explained from universal gas formula as follows

PV = nRT

P , R and T is constant ,

V ∝ n

Volume is proportional to n which depends upon number of molecules .

So volume will increase if number of molecules increases .
