Atom 1 has 6 electrons. It gains 2 more electrons from atom 2 which has 5 electrons. Who will be in charge of Atom 1 and Atom 2?

if a balloon had an initial volume of 100ml at pressure of 3.2 atm and the pressure was decreased to 1.9 atm, what would the new

hram777 [196]

Answer:

168.4 mL

Explanation:

Data Given

initial volume V1 of gas in balloon = 100 mL

initial pressure P1 of gas in balloon = 3.2 atm

final pressure P2 of gas in balloon = 1.9 atm

final volume V2 of gas in balloon = ?

Solution:

This problem will be solved by using Boyle's law equation at constant Temperature.

The formula used

P1V1 = P2V2

As we have to find out Volume, so rearrange the above equation

V2 = P1V1 / P2

Put value from the data given

V2 = 100 mL x 3.2 atm / 1.9 atm

V2 = 168.4 mL

So the final Volume of gas in baloon = 168.4 mL

Consider an experimental setup with two compartments separated by a phospholipid bilayer membrane containing ion channels select

Schach [20]

This question is incomplete, the complete question is;

Consider an experimental setup with two compartments separated by a phospholipid bilayer membrane containing ion channels selectively permeable only to chloride ions. The left compartment (also called inside) contains 1 mM Cl- and the right compartment (also called outside) contains 100 mM Cl-. What will the electrical potential be when the system attains equilibrium? [ assume body temperature; log 100 = 2, log 10 = 1, log 1 = 0, log 0.1 = -1, log 0.01 = -2]

Options;

a) -62 mV

b) -124 mV

c) +62 mV

d) 0 mV

e) +124 mV

Answer:

the electrical potential be when the system attains equilibrium is –124mV

Option b) –124mV is the correct answer

Explanation:

Given the data in the question;

Two compartments are divided by lipid bilayer;

In inside compartment Cl- ion concentration- 1mM and out side of the cell concentration is 100mM

now we apply the Nernst equilibrium potential equation;

Chlorine ion valency is z = –1

So

$E_{eq}$ = 62/z × log(ion outside/ ion inside) [for Cl‐ ions]

$E_{eq}$ = (62 / –1) x log( 100 / 1 )

$E_{eq}$ = -62 x 2 =

$E_{eq}$ = –124mV

Therefore, the electrical potential be when the system attains equilibrium is –124mV

Option b) –124mV is the correct answer

1.Liquids only exert pressure downward.

noname [10]

1. Liquids and gases exert pressure in all directions. Hence, the statement is false.

2. As the depth of liquid increases, so does the pressure. Hence, the statement is true.

3. Pascal's principle states that applied pressure will be transmitted throughout a fluid. Hence, statement C is true.

4. The pressure in a fluid depends only on the depth from the surface and not on the shape of the container. Hence, the statement is false.

5. Archimedes' principle involves buoyancy. Hence, statement C is true.

6. The temperature at which water boils can't be related to the weather. Hence, the statement is false.

7. A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. Hence, the statement is false.

<h3>What is a barometer?</h3>

A barometer is an instrument used to measure air pressure.

1. Since a fluid has no definite shape, its pressure applies in all directions. Liquids and gases exert pressure in all directions. Hence, the B is true.

2. Pressure increases as the depth increase. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.

3. Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

4. The pressure in a fluid depends only on the depth from the surface and not on the shape of the container.

5. Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.

6. Boiling occurs when the vapour pressure reaches or exceeds the surrounding pressure from the atmosphere or whatever else is in contact with the liquid. At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius.

Which statement explains the relationship between the amount of energy it takes to break a bond and the amount of energy release

ad-work [718]

<em>The statement that gives the relationship between energy needed in breaking a bond and the one that is released after breakin</em>g is

The amount of energy it takes to break a bond is always less than the amount of energy released when the bond is formed.

Bond energy can be regarded as amount of energy that is required in breaking a particular bond.

For a bond to be broken Energy will be added and when a bond is broken there will be release of energy

Bond breaking can be regarded as endothermic process, it is regarded as endothermic because there is a lot of energy required to be absorbed.

Where ever a bond is broken, there must be formation of another bond

Bond forming on the other hand can be regarded as exothermic process, since there is a release of releases energy.

Therefore, more energy is required in breaking of bond compare to energy released after breaking of bond.
