The number of electrons in an atom which has its quantum number n equal to 2 (n = 2) and ml equal to 2 (ml = 2) is equal to zero (0).
<h3>What is an electron?</h3>
An electron can be defined as a subatomic particle that is negatively charged and it's found outside the nucleus of the atom of a chemical element. This ultimately implies that, an electron is the opposite of a subatomic particle called proton.
<h3>What is the Pauli exclusion principle?</h3>
The Pauli exclusion principle can be defined as a principle which states that no two electrons (fermions) in a single atom can have the same numerical values for all four (4) of their electronic quantum numbers.
Furthermore, this principle states that the orbital of an atom can only contain a maximum of two (2) electrons, and they must have opposing spin orientations.
Based on Pauli exclusion principle, we can infer and logically deduce that the number of electrons in an atom which has its quantum number n equal to 2 (n = 2) and ml equal to 2 (ml = 2) would be equal to zero (0).

Answer:
1.3M
Explanation:
Convert from grams to moles:
molar mass of HCl = 1.01g(molar mass of H) + 35.45g(molar mass of Cl) = 36.46g HCl
1.2g HCl (1mol HCl/36.46g HCl)
= .0329 mol HCl
Molarity = mol/L (important formula for concentration)
Plug your values in:
Molarity = .0329mol/.025L
1.317M - but you used two significant figures in the question, so:
1.3M
The following directions for diluting a 10.0 M answer to a 1.00 M solution is no longer correct.
<h3>.What is the rule of dilution?</h3>
A popular rule to use in calculating the attention of solutions in a sequence is to multiply the unique concentration by means of the first dilution factor, this by the second dilution factor, this by the 1/3 dilution factor, and so on till the ultimate attention is known.
Example: A 5M answer of HCl is diluted 1/5.
<h3>How do you do a 1 in 10 dilution?</h3>
For example, to make a 1:10 dilution of a 1M NaCl solution, you would combine one "part" of the 1M solution with 9 "parts" of solvent (probably water), for a total of ten "parts." Therefore, 1:10 dilution ability 1 part + 9 components of water (or different diluent).

Answer:
All forms of energy are either potential or kinetic energy. Potential refers to stored energy while kinetic is energy in motion.
