is p4s3 a conductor
Answers
Answer:
It depends on the state.
Explanation:
Phosphorus sesquisulfide (p4s3) is a poor conductor of electricity because it is an ionic compound which is present in solid form. Ionic compounds in solid form are poor conductors of electricity due to tightly holding of their ions to one another while on the other hand, it is a good conductor of electricity in molten or liquid form due to its movement of ions in the liquid so it depends on the state of the compound.

A covalent molecule Q contains exactly 6 shared electrons. What is Q
Answers
Answer:
oxygen has six shared electrons
Covalent molecules are the group of atoms that shares a covalent bond. Ammonia is a molecule that shares three pairs or six electrons to form a covalent bond.
What are covalent bonds?Covalent bonds are the intermolecular bonds that mutually involve the sharing of electrons between the two or more atoms of the molecules. In ammonia three pairs of electrons are in a covalent bond.
In an ammonia molecule nitrogen have five electrons in its outer shells and hydrogen have one electron each. When three hydrogen shares their electrons with nitrogen to make a covalent bond the octet of the nitrogen atom is completed.
Therefore, covalent molecule Q is ammonia.

Discuss two properties of the atomic structure of copper that make it a good conductor.
Answers
The two properties of the atomic structure of copper that make it a good conductor is:
In copper, there is enough heat energy at ordinary room temperatures to liberate a vast number of weakly held valence electrons. The presence of a large number of free electrons in copper, as in other metals, is what makes it a good conductor of electricity.In copper, at normal room temperature, there is enough thermal energy to eject a large number of weakly held valence electrons. Like other metals, copper has a large number of free electrons, which makes it a good conductor of electricity.
In order for current to flow through metal, the current source must fight resistance. The lower the resistivity, the higher the electrical conductivity of the metal. Copper wire is also a good electrical conductor due to its low resistivity.
Other materials sometimes used as conductors are silver, gold, and aluminum. Copper is still the most popular material for wire because it is a very good conductor of electricity and is very cheap compared to gold and silver.

Three elements in the same period are listed in order of decreasing atomic radius. Which of the following is an appropriate explanation for the non-metal in the list having the smallest atomic radius
Answers
The appropriate explanation for the non-metal is that the higher effective nuclear charge less will be the atomic radius.
Atomic radius typically decreases during a period from left to right. There are a few little outliers, such how the oxygen radius is a tiny bit bigger than the nitrogen radius. Protons are gradually added to the nucleus at the same time that electrons are gradually added to the main energy level. The enhanced positive charge of the nucleus gradually attracts these electrons closer to it. The size of the atoms shrinks as the strength of attraction between nuclei and electrons grows. Due to electron-electron repulsions that would otherwise result in the atom's size expanding, the effect becomes less pronounced as one proceeds further to the right in a period.

how many of the following nuclei have a nuclear spin and are nmr active?
15N 19F 29Si 16O 194Pt
Answers
All of the nuclei listed have a nuclear spin, but not all of them are NMR active. Of the nuclei listed, 15N, 19F, and 29Si are NMR active, while 16O and 194Pt are not. This is because 16O and 194Pt both have a spin quantum number of zero, meaning that they have no magnetic moment and are therefore not NMR active.
Nuclei are considered NMR active if they have a non-zero magnetic moment and are present in sufficient amounts to produce a detectable NMR signal.
Nuclear spin is a fundamental property of the nucleus of an atom that arises from the intrinsic angular momentum of its constituent protons and neutrons. It is an intrinsic property of a nucleus, which means that it is a property that is inherent to the nucleus and does not depend on any external factors.

The term _____ is used to describe how well the electron cloud around an atom responds to changes in its electronic environment. A larger atom will hold its valence electrons _____ tightly than a smaller atom and will therefore have a greater response to the presence of a charged or polar particle nearby.
Answers
Answer:
polarizability, less
Explanation:
When any two ions of opposite charge and of different sizes approach each other closely, the cation tries to attracts the outermost electron of other ion and the result is called polarization.
Thus ,the ability of the cation to polarize the nearby anion is known as the polarizing power of the cation.
It is the measurement of how comfortably or effortlessly the electron cloud gets distorted by an electric field.
The valence electrons of a large size atom is loosely bound and thus they are highly react to the presence of a polar particle or charged particle which lies nearby.

A certain kind of light has a wavelength of 850 nm. What is the frequency of this light in Hz?
Use c=2.998×108ms for the speed of light.
Select the correct answer below:
a.3.5×1014
b.5.3×1014
c.3.5×1011
d.7.9×1013
Answers
The frequency of this light in Hz is 3.5×10¹⁴
So, the correct answer is A.
The frequency of a certain kind of light with a wavelength of 850 nm can be determined using the formula f=c/λ, where f is the frequency, c is the speed of light and λ is the wavelength.
Substituting the given values, we get f = (2.998×10⁸ m/s)/(850×10⁻⁹m) = 3.53×10¹⁴ Hz.
Therefore, the correct answer is option a, 3.5×10¹⁴ Hz.
It is important to note that the speed of light is a constant value and is typically denoted by the letter "c".
The wavelength and frequency of electromagnetic radiation are inversely proportional, meaning that as the wavelength decreases, the frequency increases. This relationship is known as the wave-particle duality of light and is a fundamental concept in physics.

You mix 2 moles of hbr with 3 moles of koh in enough water to make 1 l of solution. how much kbr do you expect to make?
Answers
If we mixed 3 moles of HBr with 2 moles of KOH in enough water to make 1 liter of solution, then the amount of KBr that would be formed would be 3 moles.
The balanced chemical equation for the reaction between HBr and KOH is:
HBr + KOH → KBr + H2O
In the given case, we have 3 moles of HBr and 2 moles of KOH
Their mole ratio = 1.5:1.
This means that for every 1.5 moles of HBr, we have 1 mole of KOH, which will be enough to react with all the HBr.
So, the amount of KBr formed would be 3 moles, which is the same as the amount of HBr that was added to the reaction.

Answer:
Explanation:
Firstly, let's define what ground and excited state electronic configuration.
Ground state electronic configuration is when the electrons of the atom are in there lowest possible energy level while excited state electronic configuration is when electron(s) have moved to a higher energy level. Examples of these are provided in the options
a. 1s²2s²2p⁴ - This is a ground state electronic configuration (of oxygen) because the electrons are in there lowest possible energy level.
b. This option is not displaying (it is displaying something like an image that isn't loading)
c. 1s²2s²2p³3s¹ - We can see from this that an electron jumped from 2p energy level to 3s (p energy level ought to be completely filled with 6 electrons before another electron moves to the next energy level) meaning the electron is in it's excited state thus this is an excited state electronic configuration (of oxygen).
d. 1s²2s¹2p² - We can see from this also that an electron jumped from the 2s energy level to the 2p energy level (making it 2p² instead of 2p¹ in the ground state). The 2s energy level should ordinarily have 2 electrons. Thus, this is an excited state electronic configuration (of boron).
e. 1s²2s²sp¹ - This is a ground state electronic configuration (of boron) since all the electrons are in there lowest possible energy level.
f. 1s²2s³ - This configuration is impossible because the s energy level should only contain a maximum of 2 electrons, thus impossible to have 3 electrons in the s energy level
