when Kc = [the concentration of products]^(no.of its mol in the balanced equation)     /  [the concentration of the reactants]^(no.of mol in the balanced equation)
∴ The equilibrium constant expression for this reaction is:
Kc= [H+]^2 * [So4-2] / [H2SO4]

Answer:

Keq =\frac{[H+]^{2} [SO4^{2-}]^{2}  }{[H2SO4]}

Explanation:

The equilibrium constant K is a parameter that relates the concentration of products to that of the reactants at equilibrium and under a given temperature.

Consider a hypothetical reaction:

xA + yB ↔ zC

where A and B are the reactants ;  C is the product

x and y are the coefficients of the reactants; z is the product coefficient

The equilibrium constant is given as:

Keq = \frac{[C]^{z} }{[A]^{x}[B]^{y}}

The given reaction is:

H2SO4(aq)\rightleftharpoons 2H+(aq)+ SO_{4}^{2-}(aq)

Keq =\frac{[H+]^{2} [SO4^{2-}]^{2}}{[H2SO4]}

What does the group number of element 114 have to do with its stability?
zhenek [66]

Answer:

Super-heavy elements like 114 usually only exist for fractions of a second. ... The physicists called these magic numbers the “island of stability”, because the elements with the numbers cluster together on the periodic table, flanked on all sides by ephemeral elements that dissipate in nanoseconds.
