What is Cesium abbreviated

Agas has a pressure of 6.58 kPa at 540 K. What will the pressure be at 210 K if the volume

WARRIOR [948]

Answer:

$P_2=2.6kPa$

Explanation:

Hello there!

In this case, according to the Gay-Lussac's gas law, which illustrates the pressure-temperature behavior as a directly proportional relationship:

$\frac{P_2}{T_2}=\frac{P_1}{T_1}$

We can solve for the final pressure as shown below:

$P_2=\frac{P_1T_2}{T_1}$

Thus, we plug in the initial pressure and temperature and final temperature to obtain:

$P_2=\frac{6.58kPa*210K}{540K}\\\\ P_2=2.6kPa$

Which is not among the choices.

Regards!

ASAP Which of these mixtures would best be separated through distillation?

sveta [45]

Answer:

Water and acetone is best by separated through distillation

The correct answer would be option C Acetone and water.

Explanation:

When in a mixture of fluid solution, two liquids are mixed in a form of mixture then these liquid can be separated only one method which is based on the fact. That two different liquids will have two different boiling temperatures which method of separating the Fluids is distillation.

The different liquids that are present in mixture are boiled and the vapours are condensed and the condensed portion is accumulated in another beaker.
