Why are polar gases, such as H2O and NH3, more likely to deviate from the ideal gas behaviors described by the kinetic molecular theory? (3 points)

Question 4 options:

1)

The density of these gases is high, increasing the number of collisions and reducing their elasticity.

2)

The fluidity of these gases is high, resulting in a higher average kinetic energy.

3)

The particles have a significant volume, reducing the space between the moving particles.

4)

The particles have high intermolecular forces, reducing the elasticity of their collisions.

Answer:

I believe forming an environmental personality is more important than forming a hereditary personality. Why I said this is because of the people around out can change your personality, and sometimes if you're with the wrong people, it can go wrong, with your personality too. You could have been a nice person at some time, you bur you hung out with the wrong people and now you're just very inconsiderate. Another reason on why I believe forming an environmental personality is more important because of the fact that maybe you could've been born with a parent who has a bad personality. You could try your best to be nicer by the choice of people you choose to be friends with.

Answer:

Metal

Non-metal

Explanation:

CaF2 is an ionic compound. Ionic compounds are mostly composed of a metal and a non metal. Metals donate electrons to non-metals to form ionic compounds.

Calcium is a divalent ion of group two in the periodic table while F is a univalent nonmetal of group 17 in the periodic table. Hence the compound CaF2 is composed of a metal and a nonmetal.

The moon was located at position C in its orbit during the 2015 supermoon total lunar eclipse.

A supermoon can be described as a full moon that nearly coincides with perigee which is the closest that the Moon comes to the Earth in its elliptic orbit as results in a slightly larger-than-usual apparent size of the lunar disk can be viewed from the earth.

Perigee syzygy is the technical name of the Earth-Moon-Sun system or a full Moon around perigee. The association of the Moon with oceanic and crustal tides claims that the supermoon phenomenon can be associated with an increased risk of events such as volcanic eruptions and earthquakes, but no such connection has been found.

In the 21st century, there are 87 lunar eclipses in total, of which 6 are micro moons and 28 are supermoons. A supermoon lunar eclipse was seen in the September 2015 lunar eclipse.

Answer:

i think it's B sorry if i'm wrong

Answer:

The pressure at 210 K will be 2.53 atm.

Explanation:

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

This law mathematically indicates that the quotient between pressure and temperature is constant:

[tex]\frac{P}{T} =k[/tex]

You want to study two different states, an initial state and a final state. You have a gas that is at a pressure P1 and at a temperature T1 at the beginning of the experiment. By varying the temperature to a new value T2, then the pressure will change to P2, and the following will be fulfilled:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{6.5 atm}{540 K} =\frac{P2}{210 K}[/tex]

Solving:

[tex]P2=210 K*\frac{6.5 atm}{540 K}[/tex]

P2=2.53 atm

The pressure at 210 K will be 2.53 atm.

Answer:

the ion-dipole forces between the ions and the water molecules

Explanation:

Water is a polar molecule having a high dipole moment. This high polarity makes it a popular choice of polar solvent.

CuSO4 is an ionic compound composed of Cu^2+ and SO4^2-. When dissolved in water, the positive dipole in water interacts with the negative ion while the negative dipole in water interacts with the positive ion thereby causing the compound(CuSO4 ) to dissolve in water due to the ion-dipole forces between the ions and the water molecules.

Answer:

Explanation:

Using the ideal gas 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)

Based on the information provided in this question;

P = 1.6atm

n = 4.4 moles

R = 0.0821 L*atm/mol*K

T = 32.9°C = 32.9 + 273 = 305.9K

Answer:

Products

Explanation:

In an endothermic reaction, energy is taken in. This means that the absorption of energy favours the forward reaction.

Hence for a process; A + B----> C, if energy must be added for the equilibrium to shift towards the right and more of C is produced, then the reaction is endothermic.

Explanation:

The species with a positive charge over it, which means lack of electrons are called cations. Whereas the species with negative over it, meaning it has an excess of electrons with it are called anions.

From the list given the cations are

H+, Ba2+, Hg2+, Li+, Ca2+ and Fe2+

Whereas anions from the list are

O-2, Br-5, F-, S-2.

A Combination of cation and anions make an ionic compound in which cation is written first and then anion.

Sand and water can be separated by any of the following methods:

1. Sedimentation and decantation: This method involves the mixture being kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container. Now, water is poured into another container to separate it from sand.

2. Filtration: This method involves the mixture being passed through a filter paper (a filter with very fine pores). Sand particles being larger in size are retained by the filter paper and get separated from water.

Explanation:

Mole of H2 = m/mw = 4/2 = 2 mol

From the equation

1 mol H2 --> 1/2 mol CH3OH

2 mol H2 -->??

So we have 1 mol Ch3oh

Mass of Ch3oh = mole *Mw = 1* 32.04

= 32.04g >>> the theoretically

For percent yeild = actual / theoretical * 100%

The mass of a sample of f NH₃ containing  3.80 x 10²⁴ molecules of  NH₃ is  107.27 grams.

A molecule is a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.

6.02214076 × 10²³  molecules constitute 1 mole of NH₃

3.80 x 10²⁴ molecules constitutes of = 6.31 moles

1 mole of NH₃ = 17 gm

11.19 mole will be = 17 X 6.31

= 107.27 grams

Therefore the mass of a sample of NH₃ containing 3.80 x 10²⁴ molecules of NH₃ is 107.27 grams.

The question is incomplete, the complete question is;

Some carbonated beverages are made by forcing carbon dioxide gas into a beverage solution. When a bottle

of one kind of carbonated beverage is first opened, the beverage has a pH value of 3.

After the beverage bottle is left open for several hours, the hydronium ion concentration in the beverage

solution decreases to 1/1000 of the original concentration. Determine the new pH of the beverage solution.

Answer:

6

Explanation:

Recall that

pH= -log[H3O^+]

Hence, [H^+] when the drink was first opened;

3 = -log[H^3O+]

[H^+] = Antilog(-3)

[H30^+] = 1 * 10^-3

Since [H3O^+] decreases to 1/1000 times its original value;

New [H3O^+] =  1 * 10^-3 * 1/1000 = 1 * 10^-6

Hence,

New pH = -log[1 * 10^-6]

New pH = 6

Answer:

Debido al descubrimiento de protones, neutrones y electrones.

Explicación:

La teoría de Demócrito fue reemplazada por la teoría de Dalton y luego la teoría de Dalton fue reemplazada por la de Rutherford debido al descubrimiento de protones, neutrones y electrones que están presentes dentro del átomo. Demócrito afirma que el átomo es una partícula indivisible de materia, pero el descubrimiento del protón, el neutrón y el electrón cambió este concepto de átomo, por lo que debido al mayor descubrimiento y estudio del átomo y sus partículas subatómicas, las teorías cambiaron con el paso del tiempo.
