Add all of the values up and then divide by the # of values there are.
(a) The electron kinetic energy is
which can be converted into Joule by keeping in mind that
So that we find
The kinetic energy of the electron is related to its momentum p by:
where m is the electron mass. Re-arranging the equation, we find
And now we can use De Broglie's relationship to find its wavelength:
where h is the Planck constant.
(b) By using the same procedure of part (a), we can convert the photon energy into Joules:
The energy of a photon is related to its frequency f by:
where h is the Planck constant. Re-arranging the equation, we find
And now we can use the relationship between frequency f, speed of light c and wavelength
of a photon, to find its wavelength:
Explanation:
In an acid solution, the concentration of H₃O⁺ ions is more than OH⁻
In a basic solution, the concentration of OH⁻ is more than that of H₃O⁺
By definition:
According to Arrhenius theory;
An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution. The hydroxonium ions formed as a result of the chemical bonding between the oxygen of water molecules and the protons released by the acid due to its ionization.
A base is a substance that interacts with water to produce excess hydroxide ions, OH⁻ in an aqueous solution. The common bases are NaOH and KOH
