<span>Hay cuatro números cuánticos: n, ℓ, m, y s. Cada uno es un factor particular en una ecuación que describe una propiedad del electrón. En este nivel introductorio, las ecuaciones no son necesarias. El valor de cada número cuántico se asigna a cada electrón en un átomo mediante un proceso de "construcción". Niels Bohr llamó a este proceso el principio de "Aufbau": aufbau significa "construir". N es SIEMPRE el punto de partida para construir una serie de números cuánticos. Cada número cuántico se asigna entonces de acuerdo a un conjunto de reglas, cada una de las cuales tomó años de estudio para finalmente determinar. Las reglas NO son sólo las viejas arbitrarias; Se han determinado a partir de un estudio de la naturaleza. Recuerde las reglas: (1) n = 1, 2, 3, y así sucesivamente. (2) ℓ = 0, 1, 2,. . . , N - 1 (3) m empieza en negativo ℓ, pasa por números enteros a cero y luego pasa a ℓ positivo. (4) después de haber determinado los n, ℓ y m, asignar el valor +1/2 a un electrón, luego asignar -1/2 al siguiente electrón, utilizando los mismos valores n, ℓ ym. Además, tenga en cuenta que usamos sólo un valor n, ℓ, m, y s para hacer un conjunto de cuatro números cuánticos para cada electrón. Es el conjunto que identifica de forma única cada electrón. Último punto: la última columna de cada tabla se denomina "Nombre Orbital". Al leer este tutorial, es posible que aún no sepa lo que es un orbital. Eso está bien, pero por favor entienda el concepto llamado "orbital" es importante. Aquí está una descripción simple real que ignora muchos detalles: cada orbital es una región del espacio alrededor del núcleo que contiene un MÁXIMO de dos electrones. Darse cuenta de que es más complejo que eso, pero la descripción anterior es lo suficientemente bueno por ahora. </span>

Why doesn't gold react with oxygon

lara31 [8.8K]

Give me a thanks I been helped a lot of people and non of them is thanks me.

<span>Gold have a single outer electron. This seems disadvantageous, energy-wise, until you look at the orbitals the electrons are in. The lone electron is in an S-orbital. This orbital is thus half full (since s-orbitals can contain 2 electrons), whereas all the other inner orbitals in silver and gold are filled, and hence exceptionally stable. After a full orbital, the next most stable orbital is a half full one. </span>

The total concentration of ions in a 0.75 M solution of HCl is

EastWind [94]

<h3>Answer:</h3>

The total concentration of ions in a 0.75 M solution of HCl is 1.5 M

That is; 0.75 M H⁺ and 0.75 M Cl⁻

<h3>Explanation:</h3>

Concentration or molarity is the number of moles of a compound or an ion contained in one liter of solution. It is measured in moles per liter (M).
The concentration of ions making a compound is determined by the ratio of moles of the compound and the constituents ions.

For instance, HCl dissociates to give H⁺ and Cl⁻

HCl(aq) → H⁺(aq) + Cl⁻(aq)

Therefore, since the mole ratio between HCl and the constituent ions H⁺ and Cl⁻ is 1:1, then 0.75 M of HCl dissociates to give 0.75 M H⁺ and 0.75 m Cl⁻

Hence the total concentration of ions in a 0.75 M solution of HCl is 1.5 M (0.75 M H⁺ and 0.75 M Cl⁻)

Classify each of these soluble solutes as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. Solutes formula hydroch

matrenka [14]

Compounds which on dissolving in water gets completely dissociates into its ions are known as strong electrolytes whereas compounds which on dissolving in water gets partially dissociates into its ions are known as weak electrolytes.

Substances which gives solution on dissolving in water and do not dissociates into ions also does not conduct electric current are known as nonelectrolyte.

Hydrochloric acid, $HCl$

On adding $HCl$ (strong acid) in water, it will completely dissociates into ions ( $H^{+}$ and $Cl^{-}$ ) and thus, it is a strong electrolyte.

Sodium hydroxide, $NaOH$

On adding $NaOH$ (strong base) in water, it will completely dissociates into ions ( $Na^{+}$ and $OH^{-}$ ) and thus, it is a strong electrolyte.

Formic acid, $HCOOH$

On adding $HCOOH$ (weak acid) in water, it will partially dissociates into ions ( $H^{+}$ and $HCOO^{-}$ ) and thus, it is a weak electrolyte.

Methyl amine, $CH_3NH_2$

On adding $CH_3NH_2$ (weak base) in water, it will partially dissociates into ions ( $CH_3NH_3^{+}$ and $OH^{-}$ ) and thus, it is a weak electrolyte.

Potassium chloride, $KCl$

On adding $KCl$ in water, it will completely dissociates into ions ( $K^{+}$ and $Cl^{-}$ ) and thus, it is a strong electrolyte.

Ethanol, $C_2H_5OH$

On adding $C_2H_5OH$ in water, it will not dissociates into ions and thus, it is a nonelectrolyte.

Sucrose, $C_{12}H_{22}O_{11}$

On adding $C_{12}H_{22}O_{11}$ in water, it will not dissociates into ions and thus, it is a nonelectrolyte.
