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.

Answer:

247.2g

Explanation:

Using the general gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information in this question, a fuel tank contains 150. L (V) of H2 gas at 20.0 atm (P) at 25.0˚C (T)

Temperature = 25°C = 25 + 273 = 298K

Using PV = nRT

20 × 150 = n × 0.0821 × 298

3000 = 24.4658n

n = 3000/24.4658

n = 122.62

n = 122.6mol

Using the formula, mole = mass/molar mass, to find the mass of H2 gas.

Molar mass of H2 = 1.008(2)

= 2.016g/mol

122.6 = mass/2.016

mass = 122.6 × 2.016

mass = 247.2g.

Explanation:

Recall that the density of a gas is its mass to volume ratio,  

ρ

=

m

V

. Therefore, if we can determine the mass of some volume of a gas, we will get its density. The density of an unknown gas can used to determine its molar mass and thereby assist in its identification. The ideal gas law, PV = nRT, provides us with a means of deriving such a mathematical formula to relate the density of a gas to its volume

Answer:

4. Daughter nuclide

5. Fusion

6. Strong nuclear force

Explanation:

4. When an atom of an element decays to a new element, the new element is called the

In a radioactive decay in nuclear physics, the product of the decay which is usually smaller (loss in mass) than its source and may or may not be radioactive is the daughter nuclide. Its source is the parent nuclide

5. Nuclear fusion is the nuclear process that involves the combination of two or more (light) atoms to produce subatomic particles and one or more atomic nucleus accompanied by an emission or absorption of energy due to the difference between the weight of the reactants and the weight of the products

The given reaction, is presented as follows;

³₂He + ¹₁H → ⁴₂He + ⁰₁e

Therefore, given that two atoms, (³₂He and ¹₁H) combine to form one atom (⁴₂He) and a subatomic electron particle (⁰₁e), the reaction is a fusion reaction

6. What keeps a nucleus together

The nucleus is made of neutrons and protons. There is an attractive nuclear force between protons and neutrons and a repulsive electromagnetic force between two or more protons. However, due to the proximity of the of the neutrons and the protons, which are together known as the nucleons, the attractive nuclear force is stronger than the electromagnetic force pushing the protons away from each other and the nucleus is kept together

Therefore, the strong nuclear force keeps the nucleus together.

Explanation:

Balanced Chemical equations are those equations that has the equal number of atoms of elements on both the reactants and the product sides. To ensure that the chemical equations are correctly balanced the following steps should be observed.

--> identify the elements on the reactant side and on the product side

--> identify the number of atoms of each elements.

--> multiply the number of atoms with the number that will give you a coefficient that will make both the reactant and product sides equal.

--> place the new numbers infront of the elements or compounds.

Answer:

2.24 M

Explanation:

Molality is a measure of molar concentration of a solution and it can be calculated using the formula;

Molality = mole of solute ÷ kg of solvent

To calculate the number of moles present in the solute, we use the formula;

mole = mass ÷ molar mass

Molar mass of Fe(ClO2)3 = 56 + {35.5 + 16(2)}3

= 56 + (35.5 + 32)3

= 56 + (67.5)3

= 56 + 202.5

= 258.5g/mol

mole = 435/258.5

mole of Fe(ClO2)3 = 1.68mol

750g of solvent = 750/1000 = 0.750kg of solvent

Molality of the solution is thus: 1.68/0.750

Molality = 2.24 M.

Answer:

1.3 atm

Explanation:

Apply the ideal gas law: PV = nRT

Since we need to find the pressure, solve for pressure:

P = nRT / V

Plug in our given values of n = 4.6 moles, R = 0.08206 (ideal gas law constant using atm), T = 325 K, and V = 96.8 L:

P = 4.6(0.08206)(325) / 96.8 = 1.267 atm -> 1.3 atm (two significant figures)

Answer:

Carbon is an element that's found all over the world and in every living thing. Oxygen is another element that's in the air we breathe. When carbon and oxygen bond together, they form a colorless, odorless gas called carbon dioxide, which is a heat-trapping greenhouse gas. Whenever we burn fossil fuels such as coal, oil, and natural gas—whether it's to drive our cars, use electricity, or make products—we are producing carbon dioxide.

The atmosphere isn't the only part of the Earth that has carbon. The oceans store large amounts of carbon, and so do plants, soil, and deposits of coal, oil, and natural gas deep underground. Carbon naturally moves from one part of the Earth to another through the carbon cycle. But right now, by burning fossil fuels, people are adding carbon to the atmosphere (in the form of carbon dioxide) faster than natural processes can remove it. That's why the amount of carbon dioxide in the atmosphere is increasing, which is causing global climate change.
