The Lewis structure of the arsenite is shown in the image attached.

What is the Lewis structure?

We know that the Lewis structure of a compound can help us to be able to see the way that there can be a good arrangement of the atoms that we have in the compound.

There are two parts of the Lewis structure and they are;

-The symbol of the element

-The electrons in the elements shown as dots

For the arsenite, we can see tat we have one atom of arsenic and then we have two atoms of oxygen in the Lewis structure of the compound. The compound is linear in molecular geometry  but the electron domain geometry is trigonal planar.

Metal conducts electricity when the delocalized electrons allow electrons to move from one side of the metal to another transferring the electric charge. Items like wood and rubber do not have delocalized electrons so electrical charges can not flow through them.
Metal conducts heat because when the delocalized electrons are heated they move faster. When the delocalized electrons move faster they move towards the colder end of the metal and transfer the heat throughout the metal object.
Metal can be ductile and malleable because of the sea of electrons. Because the electrons move freely, they move as the positive metal ions move, which keeps the metal stable.

Five properties of metals are:

*Electric conductivity

*Heat conductivity

*Ductility and malleability

*Luster

*High melting and boiling points

Metal conducts electricity when the delocalized electrons allow electrons to move from one side of the metal to another transferring the electric charge. Items such as wood and rubber do not have delocalized electrons so electrical charges and that's why charge doesn't flow through them.

Metal conducts heat because when the delocalized electrons are heated they move faster. When the delocalized electrons move faster they move forward towards the colder end of the metal and transfer heat throughout the metal object.

Metal is ductile and malleable because of the ocean of electrons. Electrons move freely, they move as the positive metal ions move, which keeps metal stable.

Metal has luster because the ocean of electrons absorbs as well as reflects light at the same frequency. This makes the metal look shiny.

Metals acquire high melting and boiling points because of the ocean of electrons. The relation created by the positive and negative charges tends to the metals to hold in place, which gives metals high melting and boiling points.

Metals are opaque, lustrous elements that are accurate conductors of warmth and energy. maximum metals are malleable and ductile.

The process of two complementary single-stranded DNA and/or RNA molecules joining together to generate a double-stranded molecule is known as hybridization in the context of genomics. The proper base pairing between the two single-stranded molecules is necessary for the bonding.Sp3 hybridization is the process of hybridization in which the 1s and 3p orbitals of the same element are mixed and recast to create new hybrid orbitals with the same energy, symmetry, and fixed orientation in space. An example is the creation of the methane molecule.

Linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral are the five fundamental hybridization shapes.

To find the formal charge of a Lewis structure, count the number of electrons "owned" by each atom. Count all lone pairs and half of the bond electrons. The difference between the number of valence electrons in an atom and the number it has is the formal charge. Fluorine (and all halogens) tend to form bonds and have three unshared pairs of electrons. None of these atoms have a formal charge in their electronic configuration.

What is the overall equation for the reaction that produces ccl4 and hcl from ch4 and cl2?.

Answers

The balanced equation is : CH4 + Cl2 → CCl4 + 2HCl

What is balanced equation?
An equation for just a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and total charge for each component of the reaction. In other words, both sides of reaction have an equal balance of mass and charge. It is typical to balance chemical equations both for mass and charge in aqueous solutions. Equal numbers and types of atoms are produced on both both sides of the equation when balancing for mass. When the charge is balanced, there is no net charge on either side of the equation.

The overall equation for the reaction that produces CCl4 and HCl from CH4 and Cl2 is:

CH4 + Cl2 → CCl4 + 2HCl

This reaction occurs through a free-radical substitution mechanism, which involves the breaking of the carbon-hydrogen bonds of the CH4 molecule by the chlorine radical (Cl•) produced from the dissociation of Cl2. This produces a methyl radical (CH3•) which then reacts with the chlorine radical to form CCl4 and HCl.

Silicon Penta Fluoride: What is it?

Fluoride in silicon pentoxide SiF₅ is a covalent compound created when silicon and fluorine share electrons. The 14th element, silicon, has four valence electrons. So, in order to reach octet, it needs 4 more electrons.

The 17th element, fluorine, has seven valence electrons. So, to reach an octet, one electron is required. Each F shares one of its valence electrons with silicon, giving silicon more electrons than an octet by receiving nine. Each of the five bonds is a single bond.

Answers

Answer is option B- Oxaloacetate/aspartate is an alpha-keto acid/alpha-amino acid pair used in transamination.

To create the amino acid version of the keto-acid and the keto-acid version of the original amino acid, amino groups are removed from amino acids and transferred to acceptor keto-acids by the process of transamination.

An amino group is transferred from one molecule to another during transamination. The formation of -ketoglutaric acid and aspartic acid from the interaction of glutamic acid and oxaloacetic acid serves as an example of this.

The reversible transfer of an amino group from glutamate to oxaloacetate, which results in the production of aspartate, is physiologically catalyzed by the enzyme AST. The enzyme was therefore previously known as serum glutamic-oxaloacetic transaminase.

The nucleus is at the center of an atom and accounts for the maximum mass of the atoms, a nucleus contains both protons and neutrons giving it an overall positive charge because the neutrons are of neutral or zero charges. As electrons are negatively charged and are very light in comparison to a proton or neutron, it is considered negligible in front of them.
