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
Answer: explained below
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.
Gravitational potential energy is the energy stored in an object relative to its position :)
Answer : Option C) An induced dipole will be produced in the molecule on the right.
Explanation : As per the given information there is a polar molecule which is placed on the left side which has partial positive charge at one end and on other end has partial negative charge which shows that it has a dipole in it. It tries to induce the non-polar molecule which is at right side. So, there will be an induce dipole interaction between both when they are placed closer to each other.
