84 divided by 2 = 42.
2 goes into 8 four times, so there would be your 4.
Then 2 goes into 2 one time, and there would be your 2.
You check your answer by multiplying 42 by 2, which would give you, 84.
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.
The new volume if the balloon is cooled at constant pressure is 3.98 L.
Charles's law, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.
The new volume is calculated using the Charles law formula
V₁ / T₁ = V₂ / T₂
where,
V₁ = The initial volume of air = 4.24 l
T₁ = 23.00 °C into kelvin = 23 +273 =296 K
T₂ = 5.00 °C into kelvin = 5.00 + 273 = 278 K
V₂ = ?
By making V₂ subject the subject of the formula by multiplying both sides by T₂
V₂ = ( V₁ × T₂ ) / T₁
V₂ = (4.24 L × 278 K) / 296 k
= 3.98 L
Therefore, the new volume, if the balloon is cooled at constant pressure, is 3.98 L.
An air-filled balloon will contract when chilled and expand when heated. This occurs because the gas that makes up the air within the balloon expands when it is warm and contracts when it is cool.

Answer:From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups.Oct 20, 2020
