Answer : The volume of calcium hydroxide is, 32.89 ml

Explanation :

Using neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

n_1 = basicity of an acid = 1

n_2 = acidity of a base = 2

M_1 = concentration of hydrobromic acid = 0.389 M

M_2 = concentration of calcium hydroxide = 0.0887 M

V_1 = volume of hydrobromic acid = 15 ml

V_2 = volume of calcium hydroxide = ?

Now put all the given values in the above law, we get the volume of calcium hydroxide.

1\times 0.389M\times 15ml=2\times 0.0887M\times V_2

V_2=32.89ml

Therefore, the volume of calcium hydroxide is, 32.89 ml

When an electron drops from a higher energy level to a lower one, energy is emitted. in comparison, how much energy is required
NNADVOKAT [17]

Energy is released when an electron transitions from one energy level to another. In contrast, the same amount of energy is needed to carry out the process, the other way around, from the bottom elevation to the upper one.

What occurs when an electron transitions from one energy level to another?

  • The energy of the electron drops when it changes levels, and the atom releases photons. The electron emits a photon when it transitions from a greater to a lower energy level. The energy emitted is precisely the energy that is lost when an electron moves to a level with less energy.
  • An atom's electrons have negative energy. The electron must be given energy in order to be removed from the hydrogen atom, as shown by the negative sign. The quantity of energy in the atom will rise by supplying the electron with energy. Similar to how a ball on Earth chooses to rest in valleys rather than hills, the electron wants to spend the majority of its time at a lower energy level.
  • For a brief period of time, the electron remains in an excited state. The energy required to bring the electron to its lower-energy state will be released when the electron transitions between excited and unexcited states.
