draw a representation that shows the interactions between the solute and solvent in an aqueous solution of potassium bromide

1 answer:

3 0

The visualization of the solute and solvent in an aqueous solution is such that the solute molecules are surrounded by solvent molecules, which in this case is water.

The potassium bromide will be found in the form of potassium and bromide ions. Both of these ions will be surrounded by water molecules. In the case of potassium, because it is a positively charged ion, the oxygen atoms of the water molecules will be close to the ion and the hydrogen atoms will be on the other side. The opposite will occur with the bromide ions due to their negative charge.

Hello!

Answer:

$[CO]=[Cl_2]=0.01436M$

$[COCl_2]=0.00064M$

Explanation:

Hello there!

In this case, according to the given chemical reaction at equilibrium, we can set up the equilibrium expression as follows:

$K=\frac{[CO][Cl_2]}{[COCl_2]}$

Which can be written in terms of x, according to the ICE table:

$0.32=\frac{x^2}{0.015M-x}$

Thus, we solve for x to obtain that it has a value of 0.01436 M and therefore, the concentrations at equilibrium turn out to be:

$[CO]=[Cl_2]=0.01436M$

$[COCl_2]=0.015M-0.01436M=0.00064M$

Regards!

The sodium-potassium exchange pump

trapecia [35]

Answer: The correct answer is option E

Explanation:

Sodium/potassium pump is a mechanism that involves the movement of sodium ions (Na+) out of a cell and potassium ions (K+) into a cell, thereby regulating concentration of ions on both sides of a typical cell membrane.

In this situation, the sodium-potassium pump is usually helps in the establishment of the resting potential. The potassium voltage channels normally closes before the membrane potential is brought to a resting level.

In summary, sodium/potassium pump helps to maintain a balance in the system.
