If I contain 3 moles of gas in a container with a volume of 90 liters and at a temperature of 400 K, what is the pressure inside the container? 1.09 atm

Answer: The list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.

Explanation:

The amount of energy required to remove the most loosely bound electron from an isolated gaseous atom or ion is called ionization energy.

Element with a half-filled orbital requires much more energy to remove an electron. This is because element with a half-filled electronic configuration is the most stable in nature.

More stable or tightly electrons are bound to the nucleus of an atom more will be its ionization energy. This also means that smaller is the atom higher will be its ionization energy.

When we move from top to bottom in a group the size of atom increases and the attraction between nucleus of atom and its valence electrons decreases. Hence, less will be the ionization energy.

Therefore, ionization energy decreases on moving down a group.

So, the given elements Phosphorus, Bismuth, Arsenic, Antimony, Nitrogen are all group 15 elements. Hence, decreasing order of their ionization energy is as follows.

Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth

Thus, we can conclude that the list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.

Explanation:

Answer:

15.06 L

Explanation:

Using the ideal gas law equation:

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 provided in this question,

P = 3.50 atm

n = 1.9 moles

V = ?

T = 65°C = 65 + 273 = 338K

Using PV = nRT

V = nRT/P

V = (1.9 × 0.0821 × 338) ÷ (3.5)

V = 52.725 ÷ 3.5

V = 15.06 L

Answer:

See explanation

Explanation:

Let us consider the two compounds carefully. Carbon dioxide is purely a non-polar molecular compound while the bond between the C2^2- ion and Ca^2+ is ionic thereby making CaC2 an ionic compound.

Recall that ionic compounds have high melting and boiling points due to strong ionic interactions in the structure of the compound.

On the other hand, CO2 is a non-polar substance whose molecules are held together only by weak dispersion forces.

As a result of the reasons outlined above, carbon dioxide has a low boiling point and calcium carbide has a high boiling point.

Explanation:

Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.

Answer:

16

Explanation:

Metals in group 2 form ions of the sort M^2+. If they must form ionic compounds of general formula MX, then the non metal (X) must have a valency of 2 and form the ion X^2-.

Among the options listed, only elements of group 16 form ions of the sort  X^2-, hence they are able to form compounds of general formula MX with group 2 cations. Examples of such compounds include; CaS, MgS etc

Answer:

4.84 m

Explanation:

To solve this problem we need Frezing point depression.

Formula is: ΔT = Kf . m . i

ΔT = 18°C

This is data. ΔT is the difference, Freezing T° of pure solute - Freezing T° of solution.

Kf = 1.86 °C/m

m = molality. Our unknown.

i = Ions dissolved in solution, also called Van't Hoff factor.

NaCl → Na⁻  +  Cl⁻

Sodium chloride can produce 2 moles of ions.

We replace data: 18°C = 1.86 °C/m  .  m   .  2

18°C / (1.86 °C/m) . 2 = m

molality = 4.84

Answer:

42.5 amu

Explanation:

Using the ideal gas law equation;

PV = nRT

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 provided in this question;

mass = 1.9g

T = 27°C = 27 + 273 = 300K

P = 1.1atm

V = 1L

n = ?

PV = nRT

1.1 × 1 = n × 0.0821 × 300

1.1 = 24.63n

n = 1.1/24.63

n = 0.045mol

Mole = mass/molecular mass

0.045 = 1.9/M.M

M.M = 1.9/0.045

M.M = 42.54amu

Answer:

-191.7°C

Explanation:

P . V = n . R . T

That's the Ideal Gases Law. It can be useful to solve the question.

We replace data:

2.5 atm . 8 L = 3 mol . 0.082 L.atm/mol.K . T°

(2.5 atm . 8 L) / (3 mol . 0.082 L.atm/mol.K) = T°

T° = 81.3 K

We convert T° from K to C°

81.3K - 273 = -191.7°C

Answer:

The temperature is 81.3 K.

Explanation:

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:  

P*V = n*R*T

where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.

In this case:

Replacing:

2.5 atm* 8 L= 3 moles* 0.082 [tex]\frac{atm*L}{mol*K}[/tex] *T

Solving:

[tex]T=\frac{2.5 atm* 8 L}{3 moles* 0.082\frac{atm*L}{mol*K}}[/tex]

T= 81.3 K

The temperature is 81.3 K.

Answer:

Following are the solution to the given question.

Explanation:

Answer:

radioisotopes is the answer.

Explanation:

Answer:

51207 torr is the new pressure of the gas

Explanation:

We can solve this question using combined gas law that states:

P1V1T2 = P2V2T1

Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of the gas

Computing the values of the problem:

P1 = 710torr

V1 = 5.0x10²mL

T1 = 273.15 + 30°C = 303.15K

P2 = ?

V2 = 25mL

T2 = 273.15 + 820°C = 1093.15K

Replacing:

710torr*5.0x10²mL*1093.15K = P2*25mL*303.15K

3.881x10⁸torr*mL*K = P2 * 7.579x10³mL*K

P2 = 51207 torr is the new pressure of the gas

Answer:

70.34 litres

Explanation:

Using ideal gas law equation;

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 given in the question;

n = 3 moles

V = ?

P = 105.2 KPa = 105.2/101 = 1.04atm

T = 24.0°C = 24 + 273 = 297K

Using PV = nRT

1.04 × V = 3 × 0.0821 × 297

1.04V = 73.15

V = 73.15 ÷ 1.04

V = 70.34 litres.

Wavelength is the distance from crest to crest (or trough to trough).

Answer: 400 g of solute is present in the solution

Explanation:

A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion and solvent is defined as the component that is present in a larger proportion.

Saturation point of a solution is defined as the point after which the solution becomes saturated. This simply means no more solute can be added to the solution.

Mass of solvent = 800 g

At saturation point, 500 g of solvent can dissolve 250 g of solute

Applying unitary method:

800 g of solvent will dissolve = [tex]\frac{250g}{500g}\times 800g=400g[/tex] of solute

Hence, 400 g of solute is present in the solution.

Answer:

the nucleus the largest organelle in eukaryotic cells is surrounded by the cells

Answer:

a. True

b. True

c. True

d. False

Explanation:

At equilibrium condition, the amount of products must be equal to the amount of reactants means 50% of reactant is converted into product and 50% of product is converted into reactant. During equilibrium, the concentration of the products as well as reactant does not change. Yes, a collision between reactants is needed to initiate and complete the reaction. If the concentrations of the reactants are too large, the rate of the forward reaction will be faster than the reverse reaction, and some of the reactants will be converted into products until equilibrium is achieved.
