Answer:
The wavelength of the line in the emission line spectrum of hydrogen caused by the transition of the electron for the given energy levels is
Explanation:
Given :
The energy E of the electron in a hydrogen atom can be calculated from the Bohr formula:
= Rydberg energy
n = principal quantum number of the orbital
Energy of 11th orbit =
Energy of 10th orbit =
Energy difference between both the levels will corresponds to the energy of the wavelength of the line which can be calculated by using Planck's equation.
(Planck's' equation)
The wavelength of the line in the emission line spectrum of hydrogen caused by the transition of the electron for the given energy levels is
There will be so much life! Butterflies will be everywhere! Color and aliveness! Hope this helps! Have a great day! :)
Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
Answer:
- Daniel- Earth and Space
- Sanya- Chemistry
Explanation:
Daniel's study field is associated with the '<u>Earth and Space</u>' as he is attempting to explore how the frequency of tropical storms(in the atmosphere) and coastal erosion(relation with land and ocean) are interconnected to each other. He studies how the two are associated and affect life on the planet.
While Sanya's field of study would be '<u>Chemistry</u>' as she aims to study the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules('whether the discharge from industrial plants has any impact on the pH concentration of freshwater swamps in the surrounding area').
