Why is a saturated NaCl solution an example of an equilibrium system? A. Because of the reversible nature of solidifying and mel
nataly862011 [7]

Answer:

Option B, Because of the reversible nature of crystallizing and dissolving

Explanation:

Solution containing the maximum amount of solute that can be dissolved in the given solvent at the particular temperature is called saturated solution.

Reversible reaction is the reaction which can go in reverse and forward direction both on varying reaction condition.

In the saturated NaCl solution, on lowering temperature, The the dissolved NaCl molecules may crystallize. Likewise on increasing temperature, the crystallized crystals may dissolved. As the reaction moves in both the direction, therefore its considered to be equilibrium system.

Therefore, amog given, option B is correct.

Because of the reversible nature of crystallizing and dissolving

A qué periodo y grupo pertenecen los átomos de un elemento cuyos átomos presentan 12 electrones caracterizados con ml = 0. Dar c
Klio2033 [76]

Answer:

Periodo: 3.

Grupo: IIA.

Explanation:

Hola.

En este caso, es posible determinar el periodo y grupo por medio de la configuración electrónica del elemento que tiene 12 electrones:

1s^2,2s^2,2p^6,3s^2

De este modo, vemos que el termino final es 3s^2, por lo tanto, decimos que el periodo es 3, ya que este coincide con el nivel de energía. Adicionalmente, para s^2 tenemos que el átomo se encuentra en el grupo IIA ya que tiene dos electrones en su capa o nivel (3) más externa. Esto coincide con el número cuántico dado (magnético, ml=0) ya que cuando el término en la configuración electrónica tiene el subnivel s, este tiene un valor de cero.

Así, el elemento en cuestión sería Magnesio.

¡Saludos!
