Answer:
0.2425 M
Explanation:
Given mass = 9.36 g
Molar mass of NaOH = 39.997 g/mol
The formula for the calculation of moles is shown below:
Thus,

Given that:- Volume = 965 mL = 0.965 L ( 1 mL = 0.001 L )
So,
Considering:


Answer:
(a) 
(b) Rubidium
Explanation:
Hello,
This titration is carried out by assuming that the volume of base doesn't have a significant change when the mass is added, thus, we state the following data a apply the down below formula to compute the molarity of the base solution:

Solving for the molarity of base we've got:

Now, we can compute the moles of the base as:

(a) Now, one divides the provided mass over the previously computed moles to get the molecular mass of the unknown base:

(b) Subtracting the atomic mass of oxygen and hydrogen, the metal's atomic mass turns out into:

So, that atomic mass dovetails to the Rubidium's atomic mass.
Best regards.
Answer:
AlF₃ is Lewis Acid
CH₃F is Lewis Base
Explanation:
According to Lewis concept ,"those compounds which donate pair of electrons are called as Lewis Base and those accepting pair of electrons are called as Lewis Acid.
In Given Reaction,
<span> AlF</span>₃<span> + CH</span>₃<span>F → CH</span>₃⁺<span> + [AlF</span>₄<span>]</span>⁻
AlF₃ is acting as acid because the octet of Al is not complete, hence it has tendency to accept electrons.
CH₃F is acting as a base because the F atom containing three lone pair of electrons can donate it to Al metal resulting in the formation of electrophile i.e. CH₃⁺.
Molecule
Explanation:
The molecular formula HOH is an example of a molecule.
A molecule is the smallest particle of a substance (element or compound) capable of independent existence.
Molecules can be:
- Monoatomic with one atom e.g Neon, Argon
- Diatomic with two atoms e.g Nitrogen gas N₂
- Polyatomic e.g ozone O₃
The word molecule can also be used to refer to a covalent compound that has discrete or separate units.
The formula HOH or H₂O is a separate covalent that has an independent existence.
