Explanation:
<u>Answer:</u> The equilibrium constant for the overall reaction is
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u>
<u>Equation 2:</u> ( × 2)
The net equation follows:
The equilibrium constant for the net reaction will be the multiplication of two above equations.
If the equation is multiplied by a factor of '2', the equilibrium constant of the net reaction will be the square of the equilibrium constant of respective reaction.
The value of equilibrium constant for net reaction is:
Hence, the equilibrium constant for the overall reaction is
Explanation:
Given parameters:
Wavelength of photon = 1nm = 1 x 10⁻⁹m
Unknown:
Energy of the photon = ?
Type of radiation = ?
Solution:
The energy of a photon can be derived using the expression below:
E =
h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s
c is the speed of light = 3 x 10⁸m/s
Insert the parameters and solve;
E =
E = 1.98 x 10⁻¹⁸J
Type of radiation:
X-rays
Mass number = protons + neutrons.
An electrically neutral atom has not formed an ion yet, so as of now, the number of electrons = number of protons.
So, number of protons in gallium is = 31
Thus, mass number= 31 + 39
= 70.
