Under what conditions do you expect hydrogen gas to deviate from ideal gas behavior? Explain your answer.

Answers

Answer 1
Hydrogen is a non-polar gas with very weak intermolecular forces of attraction. Hydrogen will deviate from the ideal gas behavior at high pressure.

Superficially, the connection between the cell cycle and cancer is obvious: cell cycle machinery controls cell proliferation, and cancer is a disease of inappropriate cell proliferation. Fundamentally, all cancers permit the existence of too many cells.

As chlorine has 7 valence electrons and sodium has 1 valence electron so to become stable and complete their octets sodium will become a cation by losing one electron and chlorine will form an anion and will gain one electron in this way both will become stable and an ionic bond will form between sodium and chlorine

D. answers many questions about atoms.

Answers

Answer:

its D. answers many questions about atoms.

The modern-day quantum model of the atom is better than John Dalton’s model because it "  answers many questions about atoms."

What is quantum model ?

This concept also referred to as the quantum mechanical and wave mechanical model, would be the cornerstone of contemporary atomic theory. The fact that an electron inside an atom may only exist in a limited range of states or energy is analogous to a standing wave.

What is John Dalton’s model ?

Dalton proposed that the concept of atoms will be used to explain the laws of conservation of mass as well as definite proportions. Imagining atoms as "solid, massy, hard, impenetrable, moving objects," he claimed that almost all matter would be composed of these tiny, indivisible particles.

Dalton also stated that almost no atom might be formed, converted into another, as well as destroyed. The complex shapes of orbitals also known as electron clouds used in the quantum mechanical atomic model are areas of space where an electron is likely to be present. So rather than being based on certainty, this model would be probability based.

Therefore, the correct answer will be option (D)

How can I increase the time over which the collision occurs?

Answers

Explanation:

The laws of physics determine that the force of impact increases with the square of the increase in speed. So, if you double the speed of a car, you increase its force of impact four times. If you triple the speed, the impact is nine times as great.

Observe that the greater the time over which the collision occurs, the smaller the force acting upon the object. Thus, to minimize the effect of the force on an object involved in a collision, the time must be increased.

Which statement correctly describes the relationship between molecular structure, the strength of electrostatic forces between
molecules, and the boiling point of a substance? (1 point)
The boiling point of a substance affects the strength of electrostatic forces, which can affect the molecular
structure
The boiling point of a substance affects its molecular structure, which can affect the the strength of
electrostatic forces.
Molecular structure affects the strength of electrostatic forces, which can affect the boiling point of a
substance
Stronger electrostatic forces cause a stronger molecular structure and lower boiling points

Answers

Molecular structure affects the strength of electrostatic forces, which can affect the boiling point of a substance is the statement that correctly describes the relationship between these terms.

The molecular structure is the way in which the atoms that are in a molecule are arranged in space, this is defined by a series of forces that hold the atoms together in a specific arrangement.

The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure that surrounds the liquid, when this happens, the liquid transforms into gas.

For a compound to vaporize, the forces that hold the molecules together must be broken, this means that the boiling point of a compound depends on the attraction between the molecules, that is, on the forces that determine the molecular structure.

If the molecules are held together by strong electrostatic forces, it will take a lot of energy to push the molecules away from each other and the compound will have a very high boiling point.

Therefore, we can conclude that the boiling point depends on the molecular mass of the substance and the type of electrostatic forces present, that is, the bonds that the atoms establish with each other to form the molecule (molecular structure).

Carbon dioxide is a covalent compound. The compound contains polar C-O bonds but overall the compound is nonpolar as such the molecules are held together by only weak dispersion forces.

The compound magnesium oxide is an ionic solid. It is composed of magnesium ions and oxygen ions in a crystal lattice. Owing to the fact that the ions are very small, the lattice energy is large and the compound is almost insoluble in water.

Silicon dioxide is a covalent network solid which is composed of chains of silicon - oxygen bonds. The network solid forms a very rigid structure having a high melting point.

The types of mixtures are homogeneous and heterogeneous, you can identify these based on their features.

A mixture occurs when two or more materials are mixed or combined. For example, if you combine two or more liquids. Moreover, this can lead to two types of mixtures:

Homogenous mixtures.Heterogeneous mixture.

Each of these has defined features that affect the characteristics and properties of a mixture:

Homogenous mixtures:

Once the mixture is done its components cannot be easily identified.The composition is uniform.Some examples include lemonade, smoothy, and concrete.

Heterogeneous mixture:

The components can be easily identified and even separated after the mixture.The composition is not uniform.Some examples include salad, pizza and oil mixed with water.

After several days, all of the water evaporates and white crystals are found in the beaker. Which of following pieces of experimental evidence would best help the student to confirm that a new compound had not been made and that only a physical change occurred?
a- The solution does not change color after stirring.
b- The KCl crystals are no longer visible after mixing with water.
c- There is a temperature change in the solution during the dissolving process.
d- After the water has evaporated, the white crystals in the beaker have a mass of 20.0g

Answers

Answer:d

Explanation: over time water evaporates which leaves you with the white crystals mass

A student in a beaker mixes 20.0 g of white KCl crystals with distilled water; no crystals are visible, and the solution is clear, indicating that the physical change has occurred, which is that after the water has evaporated, the white crystals in the beaker have a mass of 20.0 g; that is option d.

What is the significance of the physical change?

The physical change includes the change in the shape and size of the substances but not the chemical change, as in the case of here the crystal, which is left behind after the evaporation of the solution without any change in the chemical composition.

Hence, a student in a beaker mixes 20.0 g of white KCl crystals with distilled water; no crystals are visible, and the solution is clear, indicating that the physical change has occurred, which is that after the water has evaporated, the white crystals in the beaker have a mass of 20.0 g; that is option d.
