The Au+ is not a multivalent ion.
What is multivalent ion?
Having more than one valency or having a valency greater than three is referred to as being multivalent (comparatively more multivalent, superlatively most multivalent).
What is ion?
Ions are atoms or groups of atoms that have a different number of electrons than proton atoms. If there are more protons than electrons, the particle is a negative ion, sometimes referred to as a cation.
The all the ions are having the valence electron is 2 so they are considered as multivalent ion, Au+ having one valence electron it is not fall under multivalent ion.

In an oil spill, is the danger greater to birds and marine
mammals than it is to fish and other organisms that live on
the ocean bottom? Why?
Answer:
Birds and marine mammals are generally considered to be more vulnerable to oil spills because they are more likely to come into direct contact with the oil, either through exposure to the oil on the surface of the water or through ingestion of oil-contaminated prey. Birds may become coated in oil when they land on the water's surface to feed or rest, and marine mammals may be exposed to oil through inhalation or ingestion of contaminated water or prey.
Explanation:
Oil spills can have significant impacts on a variety of marine species, including birds, marine mammals, fish, and organisms that live on the ocean bottom. The specific impact of an oil spill on any given species will depend on a variety of factors, including the type and amount of oil that is released, the location of the spill, and the sensitivity of the species to oil exposure.Fish and other organisms that live on the ocean bottom may also be impacted by oil spills, but they are less likely to come into direct contact with the oil and may be less sensitive to oil exposure. However, the impacts of an oil spill on these species can still be significant, as the oil can disrupt their habitats, contaminate their food sources, and impact their reproductive and survival rates.Overall, the impacts of an oil spill on any given species will depend on a variety of factors and can vary significantly depending on the circumstances of the spill.alculate E∘cell for the balanced redox reaction.

What is redox reaction?Any chemical process in which one or more of the involved chemical species' oxidation numbers change is known as an oxidation-reduction reaction, often known as a redox reaction. The phrase refers to a vast and diversified set of processes.
Redox reactions are those that include both oxidation and reduction. Redox reactions, like displacement reactions, occur when one species loses electrons while the other gains them (gaining electrons).
The redox reaction becomes:

NH3, PH3, and AsH3 are all covalent compounds. SbH3 is a metallic compound.
The boiling point of a substance is a measure of the strength of the forces that hold the molecules together in the liquid state. In general, the stronger the forces between the molecules, the higher the boiling point will be.
The boiling points of NH3, PH3, AsH3 and SbH3 show a significant variation, which can be explained in terms of the different types of intermolecular forces that are present in these substances.
NH3, PH3, and AsH3 are all covalent compounds, which means that they are composed of molecules that are held together by covalent bonds. These bonds involve the sharing of electrons between the atoms in the molecule, and they are generally quite strong.
However, the strength of the intermolecular forces in these substances can vary depending on the types of atoms that are present and the way that they are bonded together. For example, NH3 has a relatively low boiling point (-33.4 oC) because the N-H bonds in the molecule are fairly weak. This allows the molecules to move more easily and escape from the liquid state at a lower temperature.
On the other hand, PH3 and AsH3 have much higher boiling points (-87.5 oC and -62.4 oC, respectively) because the P-H and As-H bonds are stronger. This makes it more difficult for the molecules to escape from the liquid state, so they need to be heated to higher temperatures in order to boil.
SbH3, on the other hand, has a much lower boiling point (-18.4 oC) because it is a metallic compound. In metallic compounds, the atoms are held together by a network of delocalized electrons, which are not as tightly bound as the electrons in covalent bonds. This means that the intermolecular forces in metallic compounds are generally weaker, which leads to lower boiling points.
Overall, the variation in the boiling points of NH3, PH3, AsH3 and SbH3 can be explained by the different types and strengths of the intermolecular forces that are present in these substances.

Draw out the molecular orbital diagram for Ne2, starting with the 2s atomic orbitals and label each molecular orbital with the appropriate notation as done in class, i.e., σ*2s or Π2p, etc. Calculate the bond order of Ne2 and determine if you would expect this molecule to exist. Then write out the electron configuration for the molecule, and determine if this molecule would be attracted to a magnetic field.
Eight electrons in bonding molecular orbitals less seven electrons in antibonding orbitals, divided by two, will result in a bond order of one half for Ne2+. Electronic configuration of N2 is (σ1s2 σ∗1s2 σ2s2 σ∗2s2 π2px2 π2py2 σ2pz2)
This is because there are the same number of molecules that form bonds and antibonds, as predicted by molecular orbital theory. Therefore, since the bond order between its two atoms is zero, there is no such thing as a N2 molecule. The individual orbitals are shown in an orbital filling diagram as circles (or squares), and the orbitals that make up a sublevel are drawn next to one another horizontally. Principal energy level and sublevel are used to identify each sublevel. Arrows inside the circles represent electrons. To comprehend a diatomic molecular orbital , use a diatomic molecular orbital diagram. It is evident from Ne's electrical structure that its valence shell is entirely filled.

When the liquid surface comes into contact with the gas, this phrase is often employed (such as the air). Interface tension is a term used to describe the force at the surface between two liquids, such as water and oil.The liquid's particles are drawn together by several intermolecular forces, including Van der Waals forces. According to the illustration on the right, particles are drawn toward the liquid's interior along the surface.
The ratio of the surface force F to the length d along which the force acts is surface tension, indicated by the Greek variable gamma: gamma = F / d
An example of surface tension is water droplets. When utilizing a water dropper, the water pours out in a series of droplets rather than a continuous stream. The water's surface tension is what determines how the drops are shaped. The pull of gravity on the water drop is the only factor keeping it from being perfectly spherical.

When a reaction produces an insoluble salt we will notice cloudiness and solids accumulating at bottom of the test tube.
We refer to a substance as a precipitate if it creates an insoluble salt as a result of soluble compounds reacting in water (see image).Most carbonates other than sodium and potassium, most hydroxides other than sodium and potassium, lead sulfate, barium sulfate, silver chloride, silver bromide, lead iodide, and lead chloride, lead bromide, lead iodide, are insoluble in water.AgCl, PbBr2, and Hg2Cl2 are hence insoluble. The majority of silver salts are soluble. Common silver salts that are soluble are AgNO3 and Ag(C2H3O2); practically all others are insoluble. Salts of sulfate are often soluble.

draw the final organic product of the following three-step reaction of bromomethylbenzene.
The final organic product on reaction of bromomethylbenzene is carbonyl compound of ketones.
What are ketones ?
Your body produces ketones, which are acids, when it burns fat for energy. Your body's cells typically use blood glucose (sugar) as an energy source. Consuming carbohydrates provides you with glucose. Your body will burn fat for energy if your cells can't receive enough glucose. This procedure results in ketones.
The substance sodium cyanide is nucleophilic. As a result, CN behaves as a nucleophile. The bromine on the benzyl chloride molecule will act as a leaving group, which causes Br to be replaced with CN. The SN2 substitution reaction is used to carry out this reaction and 4 – bromobenzyl cyanide is formed in the 1st step.
In the next step 4 – bromobenzyl cyanide undergoes two step reaction with grignard reagent and hydronium ion. and give rise to final product which is a ketone.
