Answer:
9.54
Explanation:
Fr the question given above, the following data were:
Concentration of hydronium ion [H3O⁺] = 2.9x10¯¹⁰ M
pH =?
The pH of the solution can be obtained as follow:
pH = –Log [H3O⁺]
pH = –Log 2.9x10¯¹⁰
pH = 9.54
Thus, the pH level of the solution is 9.54
Answer : The molarity of a formic acid solution is, 0.0903 M
Explanation :
To calculate the molarity of formic acid, we use the equation given by neutralization reaction:
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
are the n-factor, molarity and volume of formic acid which is ![CH_3COOH](https://tex.z-dn.net/?f=CH_3COOH)
are the n-factor, molarity and volume of sodium hydroxide base which is NaOH.
As we are given:
![n_1=1\\M_1=?\\V_1=25.00ml\\n_2=1\\M_2=0.0567M\\V_2=39.80ml](https://tex.z-dn.net/?f=n_1%3D1%5C%5CM_1%3D%3F%5C%5CV_1%3D25.00ml%5C%5Cn_2%3D1%5C%5CM_2%3D0.0567M%5C%5CV_2%3D39.80ml)
Now put all the given values in above equation, we get:
![1\times M_1\times 25.0ml=1\times 0.0567M\times 39.80ml\\\\M_1=0.0903M](https://tex.z-dn.net/?f=1%5Ctimes%20M_1%5Ctimes%2025.0ml%3D1%5Ctimes%200.0567M%5Ctimes%2039.80ml%5C%5C%5C%5CM_1%3D0.0903M)
Hence, the molarity of a formic acid solution is, 0.0903 M

Orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
<h3>What types of hybrid orbitals are?</h3>
The five basic shapes of hybridization are linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The geometry of the orbital arrangement: Linear: Two electron groups are involved resulting in sp hybridization, the angle between the orbitals is 180°.
<h3>Why are hybrid orbitals formed?</h3>
Hybridization occurs when an atom bonds using electrons from both the s and p orbitals, creating an imbalance in the energy levels of the electrons. To equalize these energy levels, the s and p orbitals involved are combined to create hybrid orbitals.

Well I don’t know how you can “bake” a desert but if you can, try to not mix up the sugar and sand
