A client presents with fatigue, nausea, vomiting, muscle weakness, and leg cramps. The laboratory values are as follows: sodium
Ganezh [65]

Answer: The laboratory value of potassium (3.0 mmol / L) is consistent with the client's symptoms of hypokalemia.

Explanation:

Hello!

Let's solve this!

Hypokalemia is a disorder in the body's electrolyte balance, when the decrease in blood potassium (K) ion levels is below 3.5 mmol / L. Potassium losses can occur through the digestive tract: such as vomiting and

diarrhea The most frequent symptoms of potassium loss include: tiredness, muscle weakness and cramping.

In conclusion, the laboratory value of potassium (3.0 mmol / L) is consistent with the client's symptoms of hypokalemia.

Metals bond with halogens to form colorless metal halides. During an experiment, bromine water was added to a solution of potass
Anvisha [2.4K]

Answer:

Bromine displaced iodide to form iodine

Explanation:

In this experiment, liquid bromine was allowed to react with a solution of potassium iodide.

Initially, we had a colorless KI solution which was mixed with light orange Br_2. If we add a light orange solution to a colorless solution, liquid bromine will get diluted and we'll see a slight decrease in its color intensity, however, if no reaction takes place, no color change will occur.

In the experiment, however, we examine a formation of a deep brown solution. Remember that iodine solution would form a brown solution.

As a result, bromine displaced iodide anion from potassium iodide:

2~KI~(aq) + Br_2~ (l)\rightarrow 2~KBr~(aq) + I_2~(aq)
