Answer:
Explanation:
a ) All the electronic levels below n = 3 have same energy so there will not be any evolution of energy in electronic transition from n=3 to n=2 or to n= 1 .
b ) Ionisation energy of ground state = 15 x 10⁻¹⁹ J per electron
= 15 x 10⁻¹⁹ x 6.02 x 10²³ J / mol
= 90 x 10⁴ J/mol
= 900 kJ / mol
c ) the shortest wavelength (in nm) of radiation that could be absorbed without causing ionization will correspond to n = 4 to n = 6
= (11 - 2 ) x 10⁻¹⁹ J
= 9 X 10⁻¹⁹ J
= 9 X 10⁻¹⁹ J / 1.6 X 10⁻¹⁹
= 5.625 eV
= 1244 / 5.625 nm
= 221.155 nm
At STP, the volume of Cl2 is 22.4 L/mol.
11.5 L Cl2 * (1 mol Cl2/ 22.4 L Cl2)= 115/224 mol Cl2.
115/224 mol Cl2* (70.90 g Cl2/ 1 mol Cl2)= 36.4 g Cl2.
The final answer is 36.4 g Cl2.

The summers in Michigan and Florida are similar because the plants in both regions end their periods of dormancy, trees start to grow buds, and plants begin to flower.
<h3>What are the effects of summer in plants in Michigan and Florida?</h3>
Summer is a period of increased sunshine and usually results in increased in plant growth and development.
Florida experienced an increased sunshine in summer periods.
Similarly, in Michigan, plants grow abundantly in summer time.
Therefore, the summers in Michigan and Florida are similar because the plants in both regions end their periods of dormancy, trees start to grow buds, and plants begin to flower.
