A gas in a balloon at constant pressure has a volume of 185 mL at -125*C. What is its volume at 31.0*C? Show all work including
miv72 [106K]

Answer:

380 mL is the new volume

Explanation:

At constant pressure.

V₁ / T₁ = V₂ / T₂

Temperature must be in Absolute Values (T°K = T°C + 273)

-125°C + 273 = 148 K

31°C + 273 = 304 K

185 mL / 148 K = V₂ / 304 K

V₂ = (185 mL / 148 K) . 304 K → 380 mL

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!
