The value of Ka for phenol (a weak acid), C6H5OH, is 1.00×10-10. Write the equation for the reaction that goes with this equilib
I am Lyosha [343]

Answer:

Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}

Explanation:

Hello,

In this case, weak acids are characterized by the fact they do not dissociate completely, it means they do not divide into the conjugated base and acid at all, a percent only, which is quantified via equilibrium. In such a way, the chemical equation representing such incomplete dissociation is said to be:

C_6H_5OH\rightleftharpoons C_6H_5O^-+H^+

Thus, we can write the law of mass action, which consider the equilibrium concentrations of all the involved species, which is also known as the acid dissociation constant which accounts for the capacity the acid has to yield hydronium ions:

K=Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}

Best regards.

The energy of a gamma ray photon whose frequency is 5.02 x 1020 Hz?
vichka [17]

Answer:

The energy of photon is 33.28×10⁻¹⁴  J

Explanation:

Given data:

Frequency of photon = 5.02×10²⁰ Hz

Energy of photon = ?

Solution:

E = h.f

h = planc'ks constant = 6.63×10⁻³⁴ Js

by putting values,

E =  6.63×10⁻³⁴ Js × 5.02×10²⁰ Hz

        Hz = s⁻¹

E = 33.28×10⁻¹⁴  J

The energy of photon is 33.28×10⁻¹⁴  J.
