Given the equilibrium constants for the following two reactions in aqueous solution at 25 ∘C HNO2(aq)H2SO3(aq)⇌⇌H+(aq) + NO2−(aq
krok68 [10]

Answer : The value of K_c for the final reaction is, 184.09

Explanation :

The equilibrium reactions in aqueous solution are :

(1) HNO_2(aq)\rightleftharpoons H^+(aq)+NO_2^-(aq)         K_{c_1}=4.5\times 10^{-4}

(2) H_2SO_3(aq)\rightleftharpoons 2H^+(aq)+SO_3^{2-}(aq)         K_{c_2}=1.1\times 10^{-9}

The final equilibrium reaction is :

2HNO_2(aq)+SO_3^{2-}(aq)\rightleftharpoons H_2SO_3(aq)+2NO_2^-(aq)         K_{c}=?

Now we have to calculate the value of K_c for the final reaction.

Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:

K_c=\frac{(K_{c_1})^2}{K_{c_2}}

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

K_c=\frac{(4.5\times 10^{-4})^2}{1.1\times 10^{-9}}=184.09

Therefore, the value of K_c for the final reaction is, 184.09

Your TLC results for ortho-hydroxyacetophenone versus para-hydroxyacteophenone will indicate that one compound is significantly
Sloan [31]

Answer:

2-hydroxy

Explanation:

The 4-hydroxy has a reduced dipole because its two electronegative substituents give it a dipole in opposite directions. On the other hand the 2-hydroxy has dipoles that add together.

Which statement describes thermal energy?
Alona [7]

Answer: Option (d) is the correct answer.

Explanation:

Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.

So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.

Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.

Why does nuclear charge increase as you go left to right across a period
MariettaO [177]

 The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
