In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them.

A portion of a ferromagnetic material where the magnetic moments are aligned with one another because of interactions between molecules or atoms.

In ferromagnetic materials, the atoms form structures called domains.

A domain is a region inside of a material where groups of magnetic moments naturally align in the same direction.

There can be numerous domains within an object.

220.9g of water are required

Explanation:

The molar enthalpy of vaporization is defined as the heat released when 1 mole of water changes from liquid to gas.

For water, 1 mole releases 40.79kJ. To release 500kJ are necessaries:

500kJ * (1mol / 40.79kJ) = 12.26 moles are necessaries

To convert moles to grams we must use the molar mass (H2O = 18.02g/mol):

12.26 moles * (18.02g / 1 mol) =

The term for the heaviness on something's surface that exerts a force over an area is pressure. The correct option is b. pressure

From the question, we are to determine the term for the heaviness on something's surface that exerts a force over an area.

Here, we are talking about pressure.

Pressure is defined as the physical force exerted on an object. Mathematically, it is defined as the perpendicular force per unit area.

That is,

[tex]P = \frac{Force}{Area}[/tex]

Where P is the pressure

The units of pressure are Newtons per square meter (N/m²), Pascals etc.

Hence, the term for the heaviness on something's surface that exerts a force over an area is pressure. The correct option is b. pressure

Explanation:

This is because the lungs are respiratory organs in the body that are located at the either side of the thorax or chest. These are organs that are incharge of exchange of gases. The air is breathe in through the trachea i.e oxygen is inhaled and carbondioxide which is the waste product is exhaled. Gas exchange take place in the lungs.

Answer:

The initial volume in mL is 5959.2 mL

Explanation:

As the number of moles of a gas increases, the volume also increases.  Hence, number of moles and volumes are directly proportional i.e

n ∝ V

Where n is the number of moles and V is the volume

Then, n = cV

c is the proportionality constant

∴n/V = c

Hence n₁/V₁ = n₂/V₂

Where n₁ is the initial number of moles

V₁ is the initial volume

n₂ is the final number of moles

and V₂ is the final volume.

From the question,

n₁ = 0.693 moles

V₁ = ?

n₂ = 0.928 moles

V₂ = 7.98 L

Putting the values into the equation

n₁/V₁ = n₂/V₂

0.693 / V₁ = 0.928 / 7.98

Cross multiply

∴ 0.928V₁ = 0.693 × 7.98  

0.928V₁ = 5.53014

V₁ = 5.53014/0.928

V₁ = 5.9592 L

To convert to mL, multiply by 1000

∴ V₁ = 5.9592 × 1000 mL

V₁ = 5959.2 mL

Hence, the initial volume in mL is 5959.2 mL

Answer:

K = 0.5

Explanation:

Based on the reaction:

PCl₃ + Cl₂ ⇄ PCl₅

The equilibrium constant, K, is defined as:

K = P PCl₅ / P PCl₃ * P Cl₂

Where P represent the pressure at the equilibrium for each one of the gases involved in the equilibrium.

As:

P PCl₅ = 1.0atm

P PCl₃ = 1.0atm

P Cl₂ = 2.0atm

K = 1.0atm / 1.0atm * 2.0atm

Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).

Answer:

Volume of 6.5 moles of Helium at STP is 145.6954 L

Explanation:

As we know

[tex]pV = nRT[/tex]

At STP, temperature is  273.15 K  and pressure is  1 atm

n is the number of moles which is equal to 6.5

R is the gas constant = 0.08206 L atm/K mol

Substituting the given values in above equation, we get -

[tex]1 * V = 6.5 * 0.08206 * 273.15\\V = 145.6954[/tex]Liters

Volume of 6.5 moles of Helium at STP is 145.6954 L

Answer:

3.18 L

Explanation:

Step 1: Given data

Step 2: Convert P₁ to mmHg

We will use the conversion factor 1 atm = 760 mmHg.

0.985 atm × 760 mmHg/1 atm = 749 mmHg

Step 3: Calculate the final volume of the gas

Assuming ideal behavior and constant temperature, we can calculate the final volume using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 749 mmHg × 3.65 L/861.0 mmHg = 3.18 L

D - Hydroxide Ion (OH-)

Explanation:

A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
