Answer:
The correct answer is B has a neutral pH
Explanation:
we all know that acid converts blue litmus to red on the other hand base converts red litmus paper to blue.
According to the question the blue litmus paper does not change its colour or it stays blue that means the pH of solution is neutral or7 which prevent the colour change of the litmus paper.
If the solution was acidic then the blue litmus paper changes into red .
The answer to your question is,
B. Government.

The energy will be absorbed for the electron transitions n= 3 to n= 4.
There are two ways in which electrons can transition between energy levels:
- Absorption spectra: This type of spectra is seen when an electron jumps from a lower energy level to a higher energy level. In this process, energy is absorbed.
- Emission spectra: This type of spectra is seen when an electron jumps from a higher energy level to a lower energy level. In this process, energy is released in the form of photons.
for n=3 to n=4, the equation used to calculate the energy of transition is,

⁻¹⁸

Thus, for n = 3 to n = 4, as the electron is getting jumped from lower energy level (n = 3) to higher energy level (n = 4), the energy will be absorbed.
