What is hybridization?
In chemistry, orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (having different energies, shapes, etc. than the component atomic orbitals) suitable for electron pairing. Yes, they form chemical bonds through valence bond formation.
Hybridization is defined as the concept of mixing two atomic orbitals to create a new type of hybrid orbital. This mixing usually results in the formation of hybrid orbitals with very different energies, shapes, etc.

The equilibrium relation allows us to find which statement is correct:
B) The balloon will shrink.
The stable equilibrium condition that the sum of forces in a system is zero
∑ F = 0
Where F is the force
Helium is a noble gas, which has a liquefaction temperature of 4.2K, therefore in almost all cases we find it in the gaseous state
The balloon is in an equilibrium between the outside atmospheric pressure and the pressure of the helium gas inside, when the temperature decreases the energy of the helium molecules decreases and has a lower speed, therefore creating a lower pressure inside, for therefore the balloon decreases its size until the pressures equalize.
Let's examine the claims
A) False. The balloon expands with increasing temperature
B) True. The balloon should contract until it equalizes the internal and external pressure
C) False. Helium gas becomes liquid at very low temperatures (4.2K)
D) False. One of the statements describes the process well
In conclusion the equilibrium relationship we can find which statement is correct:
B) The balloon will shrink.

At the equivalence point, the NaF completely reacts with the HCl
The correct option that gives the equivalence point when titrating NaF solution with HCl(aq), occur at a pH value is option c);
c) <u>Below 7 because it is determined by HF (aq)</u>
Reason:
The ionic equation of the reaction taking place in the titration is presented as follows;
- Na⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → HF (aq)+ Na⁺(aq) + Cl⁻(aq)
Therefore, by removing the spectator ions, we get;
Therefore;
The net ionic equation is the formation of hydrofluoric acid, HF, which is a
weak acid, therefore, the pH value will be <u>below 7 because it is determined </u>
<u>by HF</u>
