When a patient comes to a hospital with severe dehydration, doctors will give them an IV filled with a salt-water solution calle

d saline, which is isotonic with the body's blood cells. Why is the patient not given pure water? *

Answer:

Patients with dehydration are given salt-water solution or saline water which creates an isotonic environment with blood cells because the isotonic solution restricts the movement of water by creating an equal concentration of solute and water on both sides of the blood membrane and it prevents any change in the cell size.

The patient is not given pure water because it makes the blood cell hypotonic and water will enter the blood cell, and the cell will swell, which can lead to the death of the patient.

4.65 L of nitrogen at standard pressure is compressed into a 0.480 L container. What is the new pressure in kPa?
Semenov [28]
Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:

P = k / V

k is equal nRT

P1V1 = P2V2
P2 = 101.325 ( 4.65 ) / .480 = 981.586 kPa

Calculate the volume in milliliters of a 0.420mol / L barlum chlorate solution that contains 25.0 g of barium chlorate (Ba(ClO 3
Pachacha [2.7K]

<u>Answer:</u> The volume of barium chlorate is 195.65 mL

<u>Explanation:</u>

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

Given mass of barium chlorate = 25.0 g

Molar mass of barium chlorate = 304.23 g/mol

Molarity of solution = 0.420 mol/L

Volume of solution = ?

Putting values in above equation, we get:

0.420mol/L=\frac{25.0\times 1000}{304.23\times V}\\\\V=\frac{25.0\times 1000}{304.23\times 0.420}=195.65mL

Hence, the volume of barium chlorate is 195.65 mL

An object's mass is less on<br> the Moon than it is on Earth.
vovikov84 [41]

Answer:

The mass of objects remains constant throughout the universe. This is because an object is made of he same amount of matter (atoms), no matter where you take it in the universe. If you take an object from the Earth to the moon, only the weight will change.
