Which of the quantum numbers relate(s) to the electron only? Which relate(s) to the orbital?

Chemistry

olganol [36]3 years ago
5 0

Answer:

Schrodinger's proposal, considered as the 5th atomic model, is to describe the characteristics of all the electrons in an atom, and for this I use what we know as quantum numbers.

Quantum numbers are called with the letters n, m, l and s and indicate the position and energy of the electron. No electron of the same atom can have the same quantum numbers.

Explanation:

n = main quantum number, which indicates the level of energy where the electron is, assumes positive integer values, from 1 to 7 and it is related to the orbital too.

I = secondary quantum number, which indicates the orbital in which the electron is located, can be s, p, d and f (0, 1, 2 and 3).

m = magnetic quantum number, represents the orientation of the orbitals in space, or the type of orbital, within a specific orbital. Assumes values ​​of the negative secondary quantum number (-l) through zero, to the positive quantum number (+ l).

s = quantum number of spin, which describes the orientation of the electron spin. This number takes into account the rotation of the electron around its own axis as it moves around the nucleus. Assumes only two values ​​+1/2 and - 1/2

An organic compound of relative molecular mass 46,on analysis was found to contain 52.0% carbon, 13.3% hydrogen and 34.7% oxygen
Nadya [2.5K]

Answer:

Empirical formula is C₂H₆O.

Explanation:

Empirical formula:

It is the simplest formula gives the ratio of atoms of different elements in small whole number

Given data:

Percentage of hydrogen = 13.3%

Percentage of carbon = 52.0%

Percentage of oxygen = 34.7%

Empirical formula = ?

Molecular formula = ?

Solution:

Number of gram atoms of H = 13.3 / 1.01 = 13 .17

Number of gram atoms of O = 34.7 / 16 = 2.17

Number of gram atoms of C = 52.0 / 12 = 4.3

Atomic ratio:

            C                     :          H             :           O

           4.3/2.17            :     13.17/2.17     :       2.17/2.17

            2                      :        6               :        1

C : H : O = 2 : 6 : 1

Empirical formula is C₂H₆O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

n = 46 / 158

The relative molecular mass of compound is not correct.

Is the statement correct or incorrect? Explain. A) It is correct. The ashes weigh less than the original wood and this proves th
Vladimir79 [104]
The correct answer is D

According to the law of conservation of mass, mass can not be destroyed or lost, it can just be rearranged in space, turned into energy etc.

Therefore, in our of example the wood was burned and turned into ashes. Even though the ashes weight less than the original wood, some of the solid mass of the wood was converted to gas and energy, so the overall mass remained the same.
