A gas has a solubility of 2.45 g/L at a pressure of 0.750 atm. What pressure wold be required to produce an aqueous solution con
Lelechka [254]

Answer:

1.91 atm

Explanation:

Step 1: Calculate Henry's constant (k)

A gas has a solubility (C) of 2.45 g/L at a pressure (P) of 0.750 atm. These two variables are related to each other through Henry's law.

C = k × P

K = C/P

K = (2.45 g/L)/0.750 atm = 3.27 g/L.atm

Step 2: Calculate the pressure required to produce an aqueous solution containing 6.25 g/L of this gas at constant temperature.

We have C = 6.25 g/L and k = 3.27 g/L.atm. The required pressure is:

C = k × P

P = C/k

P = (6.25 g/L)/(3.27 g/L.atm) = 1.91 atm

Un estudiante de noveno año decide realizar varias mezclas de compuestos quimicos y tiene un frasco rotulado con la formula quim
expeople1 [14]

Answer:

- Oxido de magnesio

Explanation:

Mg → magnesio

O → oxígeno

La unión del oxígeno (no metal) con un metal, forma el determinado óxido que se nombra como óxido de .... y el no metal.

En este caso, podemos deducir que el contenido del frasco es de óxido de magnesio, aunque viendo que hay un sólo átomo de oxígeno podemos llamarlo como monóxido de magnesio, similar al CO (monóxido de carbono).

A partir de que el magnesio sólido entre en contacto con el aire, se produce MgO de acuerdo a la siguiente reacción:

2Mg  +  O₂ →  2MgO
