Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four qu

ad-work [718]

Answer:

The allowable values for the principle quantum number (n) are integers greater than zero.

The allowable values for the angular momentum quantum number (l) are integers from 0 to n-1.

The allowable values for the magnetic quantum number (ml) are integers from -l to l.

The allowable values for the spin quantum number (ms) are -1/2 and 1/2.

Explanation:

Identify allowable combinations of quantum numbers for an electron. Select all that apply.

The allowable values for the principle quantum number (n) are integers greater than zero. TRUE. The principal quantum number (n) represents the level of energy in which an electron is and can take positive integer values.

The allowable values for the angular momentum quantum number (l) are integers from 0 to n-1. TRUE. The angular quantum number (l) represents the sublevel of energy and the kind of orbital an electron is in and can take integer values from 0 to n-1. For instance, if n = 1, l can take the value "0", which represents the sublevel and orbital "s".

The allowable values for the magnetic quantum number (ml) are integers from -l to l. TRUE. The magnetic quantum number (ml) represents the orientation of an orbital in space and can take integers values from -l to +l. For instance, if l = 1 (p orbital), ml can take the values -1, 0 and 1, which refer to orbitals px, py and pz.

The allowable values for the spin quantum number (ms) are -1/2 and 1/2. TRUE. The spin quantum number (ms) represents the spin of the electron and can take values -1/2 and +1/2.

A buffer is composed of nh3 and nh4cl. How would this buffer solution control the ph of a solution when a small amount of a stro

Shkiper50 [21]

Answer:

According to Le-chatelier principle, equilibrium will shift towards left to minimize concentration of $OH^{-}$ and keep same equilibrium constant

Explanation:

In this buffer following equilibrium exists -

$NH_{3}(aq.)+H_{2}O(l)\rightleftharpoons NH_{4}^{+}(aq.)+OH^{-}(aq.)$

So, $OH^{-}$ is involved in the above equilibrium.

When a strong base is added to this buffer, then concentration of $OH^{-}$ increases. Hence, according to Le-chatelier principle, above equilibrium will shift towards left to minimize concentration of $OH^{-}$ and keep same equilibrium constant.

Therefore excess amount of $OH^{-}$ combines with $NH_{4}^{+}$ to produce ammonia and water. So, effect of addition of strong base on pH of buffer gets minimized.
