G) The set of quantum numbers for the 6th electron in fluorine atom. ​

Chemistry
1 answer:
ycow [4]3 years ago
5 0

Answer:

n=2, l= 1, m= 0, s = +1/2

Explanation:

An electron is described by four sets of quantum numbers;

I) principal quantum number (n)

ii) orbital quantum number (l)

iii)Magnetic quantum number (m)

iv) Spin quantum number (s)

The electronic configuration of fluorine is; 1s2 2s2 2p5

Hence, the sixth electron of fluorine is found in the 2p subshell where;

n=2, l= 1, m= 0, s = +1/2

Ad libitum [116K]

the correct combo is C

We know sunlight is key factor in photosynthesis so A and D are out.

we also know plants get their bulk by breaking up co2 and using the carbon which releases oxygen as a byproduct so B is also out of the question.

what is molarity of a sodium hydroxide solution made by combining 2.0 L of 0.60 M NaOH with 495 mL of 3.0 M NaOH? Assume the vol
hammer [34]

Answer:

Molarity of the sodium hydroxide solution is 1.443 M/L

Explanation:

Given;

0.60 M concentration of NaOH contains 2.0 L

3.0 M concentration of NaOH contains 495 mL

Molarity is given as concentration of the solute per liters of the solvent.

If the volumes of the two solutions are additive, then;

the total volume of NaOH = 2 L + 0.495 L = 2.495 L

the total concentration of NaOH = 0.6 M + 3.0 M = 3.6 M

Molarity of NaOH solution = 3.6 / 2.495

Molarity of NaOH solution = 1.443 M/L

Therefore, molarity of the sodium hydroxide solution is 1.443 M/L

A researcher wants to test the solubility (property of being dissolved) of salt in water as the temperature of the water increas
Leya [2.2K]
The researcher may first weight the beaker with water and then start to heat the water to a constant temperature, for example 30 °C and then start adding salt and stirring. He should add salt slowly until solid salt starts to become visible and the solution starts becoming cloudy. When this happens, he should quickly weigh the beaker. The increase in mass is the mass of salt dissolved at that temperature.
The procedure is then repeated but at an increased temperature until 5-6 temperatures have been tested.

Which diagram shows electrons violating the Pauli exclusion principle?
Neporo4naja [7]
Correct Answer: Option C

Reason:
<span>The </span>Pauli Exclusion Principle<span> states as '<em>in an atom or molecule, no two electrons can have the same four electronic quantum numbers. Further, an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.</em>'
</span>
Thus, it can be seen that in option C, electrons in last 2 subshell have electrons with same spin, which is a violation of Pauli Exclusion Principle .
