Answer:
n = 5 to n = 6 absorption
n = 9 to n = 6 emission
n = 6 to n = 4 emission
n = 6 to n = 7 absorption
Explanation:
According to the Bohr's model of the atom. An electron in an atom may absorb energy and move from a lower energy level to a higher energy level. This requires absorption of energy that is equal to the energy difference between the two levels.
Similarly, an electron may move from a higher to a lower energy level, releasing energy that is equal to the energy difference between the higher and the lower level. This is known as emission.
Hence, if the electron is moving from a lower energy level to a higher energy level, an absorption has taken place, e.g n = 5 to n = 6
When an electron moves from a higher energy level to a lower energy level, an emission has taken place e.g n = 9 to n = 6

Explanation:
We have to remember that for any <u>equilibrium expression constant</u> we can use the general reaction:
With a equilibrium expression:
We have to <u>divide products by reagents and use the coefficient (in the balanced reaction) as exponents</u>. So:
The reaction is <u>already balanced</u>. So, we can write the equilibrium expression:
In this case, all the compounds have <u>gaseous state (g)</u>. So, we can change the concentration ([]) by the <u>pressure of each compound</u>:

Answer:
Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).
