When a sodium chloride (NaCl) solution is given to some intravenously (as an IV directly into the blood), it is usually a 0.9% NaCl solution. The reason is that a 0.9% NaCl is isotonic to your red blood cells. Use that information to answer the following questions: In the solution above, which molecule is acting as the solute and which molecule is acting as the solvent? If you replaced the 0.9% NaCl solution with pure water instead, would the water be hypertonic, hypotonic, or isotonic to your red blood cells? If you replaced the 0.9% NaCl solution with pure water instead, would the net (overall) movement of water be into the cell, out of the cell, or would there be no net movement of water? If you replaced the 0.9% NaCl solution with pure water instead and waited, what specifically would happen to your red blood cells?

Answers

Answer:

Explanation:

(1) In the IV solution, the solute here is the NaCl salt and the solvent is the liquid (water) the salt is dissolved in.

(2) If the NaCl is replace with water, the water content will become hypotonic to the red blood cells as there would be less solute in the solution than in the cell's cytosol. This also means there is more water in the solution than in the cell's cytosol.

(3) Because the water is hypotonic to the red blood cells (as described in (2) above), the net movement of water will be into the cell.

(4) If the movement of water is allowed to continue as described in (3) above (i.e if 0.9% NaCl in the solution is replaced with pure water instead and waited), the cell will rupture which can lead to cell lysis or cytolysis.

NOTE: An isotonic solution describes when there is the same amount of solute in the cell and the solution outside the cell hence there is little or no movement of water.

When a solid is placed in a container and heat is applied, a phase change occurs. Watch the video and identify which of the following statements are correct.
a) The temperature increases while all of a liquid is converted to a gas.
b) The average kinetic energy of the system changes while all of a solid is converted to a liquid.
c) Temperature remains constant while all of a solid is converted to a liquid.
d) When heat is applied to a solid, the molecular motion decreases as the temperature increases.
e) When a solid is converted to a liquid, heat is absorbed.

Answers

Answer:

Temperature remains constant while all of a solid is converted to a liquid.

When a solid is converted to a liquid, heat is absorbed.

Explanation:

During a phase change, the temperature of the system remains constant. Recall that latent heat is defined as heat that causes a change of state without a corresponding rise in temperature of the system.

When a solid is converted to a liquid, latent heat of fusion is involved hence the temperature of the system remains constant throughout the process.

Similarly, heat is absorbed as intermolecular forces are broken up and the would converts to liquid.

5. The sphere shown below is placed in a full overflow cup and sinks to the bottom. How much water is displaced by the sphere?
4.6 cm
O A. 51.0 ml
OB. 66.5 ml
O C. 88.6 mL
O D.407.7 ml

Answers

Answer : The correct option is (A) 51.0 mL

Explanation :

As we know that water displaced is equal to the volume of sphere.

Now we have to determine the volume of sphere.

Formula used:

Volume of sphere = [tex]\frac{4}{3}\pi r^3[/tex]

where,

r = radius of sphere

Given:

Diameter of sphere = 4.6 cm

Radius of sphere = [tex]\frac{Diameter}{2}=\frac{4.6cm}{2}=2.3cm[/tex]

So,

Volume of sphere = [tex]\frac{4}{3}\times 3.14\times (2.3cm)^3[/tex]

Volume of sphere = [tex]50.94cm^3\approx 51.0 cm^3[/tex]

Water displaced = Volume of sphere = [tex]51.0 cm^3[/tex]

We know that:

[tex]1cm^3=1mL[/tex]

So,

Water displaced = 51.0 mL

Therefore, the correct option is (A) 51.0 mL

Answer:

A. 51.0 mL

The answer is 1.04 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass of coke = 21.36 g

volume = 20.5 mL

So we have

[tex]density = \frac{21.36}{20.50} \\ = 1.0419512...[/tex]

We have the final answer as

1.04 g/mL

Answers

Answer:

An element is made of one type of  atom, while a compound is two or

more types of atoms combined.

Explanation:

An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.

Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.

There are over a hundred elements known to date. Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek Examples are copper, gold, ironThe properties of a compound are distinct and different from those of the individual elements that are combined in its make up. There are several millions of compounds known. They are usually represented by chemical formulae.

As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.

Carbon dioxide is in a steel tank at 20C 10 liters and 1 atm. What is the pressure on the gas when the tank is heated to 100C?

Answers

Answer:

1.273 atm

Explanation:

We are given:

P1 = 1 atm                         P2 = x atm

T1 = 20 degree celsius or 293 k        T2 = 100 degree celsius OR 373 k

Since the volume remains constant, we don't have to talk about that

From the Gas equation:

PV = nRT

Since  number of moles (n) , Universal gas constant (R) , Volume of the gas (V) are constants

P / T = k   (where k is a constant)

Hence we can say that P1 / T1 = k --------------(1)

Also, P2 / T2  = k -------------------------------------(2)

where k is the same constant

From (1) and (2):

P1 / T1 = P2 / T2

Now, plugging the values in this equation

1 / 293  = x / 373

x = 373 / 293

x = 1.273 atm

Therefore, the pressure of CO2 after increasing the temperature to 100 degree celsius is 1.273 atm
