In the bohr model of the hydrogen atom, the energy required to excite an electron from n = 2 to n = 3 is <u>greater than</u> the energy required to excite an electron from n = 3 to n = 4
Bohr's energy levels:
The essential concept of Bohr's atomic model is that electrons occupy specified orbitals that call for the electron to have a certain amount of energy. An electron needs to be in one of the permitted orbitals and have the correct amount of energy needed for that orbit in order to be in the electron cloud of an atom. An electron would require less energy to orbit near the nucleus, while an electron would need more energy to orbit away from the nucleus. Energy levels are the potential orbits. One of Bohr's models' flaws was that he was unable to explain why just specific energy levels or orbits were permitted.
It is evident that the energy required to escape an electron from n=2 to n=3 is greater than the energy required to exit an electron from n=3 to n=4. This is because as n increases, the energy levels move closer to one another.

<u>Answer:</u>
<em>We know water can exist in all three states be it solid or liquid or gas the only difference between the three states is the temperature at which they exist. </em>
<u>Explanation:</u>
When the temperature moves towards colder region the state of water changes to solid while when the temperature moves to water region the state of water changes to gas.
This little experiment can be done with the help of ice at room temperature. The more ice is applied to water it will turn to ice but removal of eyes in room temperature. And will make it turn to water and complete removal of eyes with application of heat would make it into vapour.
Answer:
Mitochondria
Explanation:
Mitochondria are organelles whose membranes are specialized for aerobic respiration.
Answer:
it identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional group
Explanation:
It turns from turquoise to yellow or orange when it reacts with reducing sugars.
Answer:
2.66g
Explanation:
Since the number of Oxygen atoms in a CO2 is doubled the number of Oxygen atoms in a CO. By the mass the weight of O2 atoms in CO2 must be twice the amount of the Oxygen mass in CO as well. So if 1 g Carbon atom of CO combine with 1.33g of Oxygen. Then that means 1 g Carbon atom of CO2 would combine with 1.33 * 2 = 2.66 g of Oxygen
