Answer:

Since all of them are aqueous solutions, the solvent in each solution is H2O. Based on the Raoult's Law, we only have to determine which solution contains the highest mole fraction of the solvent, H2O. The solution that will have the lowest vapor pressure is a. 0.20 m Na2SO4.

To make a crucible for melting sodium (Na), metals that would be most suitable for that purpose are inert metals or metals like alumina.

inert metals are those metals that do not react with other highly reactive metals or in the atmosphere due to the absence of one free electron in the outermost orbital.

The sodium metal is kept in the crucible of the inert metal like alumina because sodium has one free electron in the outer shell and catches fire as come into the contact with the air.

Therefore, to make a crucible for melting sodium (Na), metals that would be most suitable for that purpose are inert metals or metals like alumina.

Answer:

Higher pitched sounds produce waves which are closer together than for lower pitched sounds. (Think of the slinky - if you produce waves rapidly they will travel quite close to each other, thus demonstrating a higher pitched sound.)

The pitch of a note will depend on a number of factors. One of these is the size of the vibrating object. On a glockenspiel or xylophone the high notes are made by the smaller bars. A smaller triangle or cymbal will make a relatively higher pitch note. On a stringed instrument such as a guitar or violin a thinner string will generally make a higher note, but also shortening the string by stopping it with the finger will produce a similar effect. On a set of pan pipes or a church organ it is the shorter pipes which make the higher notes when the air inside them vibrates.

Another factor which produces higher pitched notes is the tension within the vibrating object. A guitar string can be tuned to a higher pitch by adjusting the string tensioner. An elastic band can be stretched tighter and a drum skin can be tensioned to increase the pitch of the sound it produces.

The 3-dimensional orientation of a sublevel is known as atomic orbital.

In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.

Each sublevel has an orbital and it is oriented differently in 3-dimensional space.

The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

Answer:

The strongest intermolecular force in sulfur dioxide is dipole-dipole forces.

Explanation:

The interparticle force in [tex]SO_{2}[/tex] (sulfur dioxide) is the dipole-dipole interaction.

Dipole-dipole interaction is a type of intermolecular force that occurs between polar molecules. Polar molecules have a permanent dipole moment, which means they have a partial positive charge on one end and a partial negative charge on the other end. This creates an electrostatic attraction between the partial charges of neighboring molecules. The stronger the dipole moment of a molecule, the stronger its dipole-dipole interaction will be with other polar molecules.

Dipole-dipole interactions are responsible for a variety of physical properties of substances, including their boiling and melting points. Substances with strong dipole-dipole interactions tend to have higher boiling and melting points than substances with weaker interactions. In addition, the strength of dipole-dipole interactions can affect solubility, as polar substances tend to dissolve better in other polar substances due to their ability to form dipole-dipole interactions.

Lustrous

Explanation:

Metals are lustrous which gives them a property of having Shiny surfaces

The valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous  property of metals.

Valence electrons are defined as a negatively charged particle that can be shared or transmitted between atoms that is found in the outermost shell of an atom. Valence electrons have a crucial role in determining how an atom will behave. The electrical configurations of elements can be used to find valence electrons. The total number of valence electrons in that element is then determined by counting the number of electrons in the outermost shell.

When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal.

Thus, the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous  property of metals.

1. Genetic factors are those where the genetic condition of an individual is capable of increasing the probability of developing certain diseases.

Environmental factors include the diversity of environmental stresses such as population density, temperature, food and pollutants that impact human health.

Social factors are related to the interaction of groups through culture, social class and family structure, which also have an effect on population health.

Pathogenic factors, on the other hand, are those transmitted by agents such as viruses, fungi, bacteria and protozoa, which colonize a host by adhering to cells and evading immunity, generating diseases.

2. The transmission of pathogens can occur in several ways, such as contact with bodily fluids from infected people, cross-transmission or through being spread through particles in the air.

3. We can prevent the transmission of pathogens through proper hygiene habits, healthy eating, vaccination against infectious diseases and avoid contact with other people if you have a communicable disease.

4. The environment can affect personal health through climate change, pollution and lack of infrastructure that lead to less access to quality food and basic health conditions.
