Which of the following elements would have six electrons in its valence enegy level?
Oxygen is in group 6 and has 6 valence electrons.
What is meant by electrons?
Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.Since electrons are fermions, the Pauli exclusion principle states that no two electrons may be in the same quantum state.Since they can collide with other particles and can be diffracted like light, electrons, like all primary particles, display both wave and particle characteristics. Because electrons have a lower mass and a longer de Broglie wavelength for a given energy, their wave properties are simpler to observe experimentally than those of other particles like neutrons and protons.To learn more about electrons refer to

Lysine is a compound composed of carbon, hydrogen, nitrogen and oxygen. when 1.50 g of lysine is burned, 2.72 g of carbon dioxide, 1.29 g of water and 0.287 g of nitrogen gas are produced. what is the empirical formula?
The empirical formula of a compound can be determined by analyzing the mass percentages of its various elements and expressing them as the smallest whole number ratio. To find the empirical formula of lysine, we first need to determine the number of moles of each element present in 1.50 g of lysine. We can then use these values to calculate the mole ratios of the elements, which will be the same as the ratio of the subscripts in the empirical formula.
By knowing the mass of produced CO2 and H2O we can calculate how many moles of C and H are present in 1.50 g of lysine
mass of C = 2.72 g CO2 x (1 mol CO2 / 44.01 g CO2) = 0.062 moles
moles of H = 1.29 g H2O x (2 moles H / 18.02 g H2O) = 0.072 moles
Then, by knowing that lysine also produced 0.287 g of N. We can calculate the number of moles of N
moles of N = 0.287 g N x (1 mole N / 28.02 g N) = 0.0102 moles
We can now find the ratio of the elements by dividing each by the smallest number of moles which is 0.0102 moles.
C:H:N = 0.062 moles / 0.0102 moles = 6:1:1
So the empirical formula of lysine is C6H14N2
why is the melting point of toluene only -95°c, whereas that of benzene is 5°c?
The primary difference between toluene and benzene is the presence of a methyl group (-CH3) on one of the carbon atoms in toluene.
What is benzene?Benzene is an organic compound and an aromatic hydrocarbon composed of six carbon atoms joined in a ring, with one hydrogen atom attached to each. It is a colorless and highly flammable liquid with a sweet smell. It is a naturally occurring component of crude oil, and it is one of the most important industrially-produced chemicals in the world.
This methyl group increases the size of the molecule and its ability to interact with other molecules. This increased interaction between molecules causes toluene to have a higher boiling point and melting point than benzene.
The melting point of toluene is -95°C, whereas the melting point of benzene is 5°C. This difference is due to the increased ability of the toluene molecule to interact with other molecules. When toluene is heated, the increased interactions between molecules cause them to move more quickly, leading to a higher melting point than benzene.
Additionally, the presence of the methyl group on the toluene molecule increases the shape of the molecule, making it less symmetrical than benzene. This asymmetry can also affect the strength of the intermolecular forces, leading to a higher melting point.
Overall, the difference in melting points between toluene and benzene can be attributed to the increased size and shape of the toluene molecule, as well as its increased ability to interact with other molecules.

Describe how ionic compounds form? Make sure to include what happens to the valence electrons. Which way does the electron travel? How do we determine the number of electrons that are transferred? And what holds them together?
Ionic compounds form through the transfer of electrons between atoms. In order for an ionic compound to form, one atom must give up one or more of its valence electrons, while another atom must gain one or more electrons to fill its valence shell.
The transfer of electrons occurs from the atom with the lower ionization energy to the atom with the higher electron affinity. This means that the electron is transferred from the element that is in the lower position in the periodic table and is more likely to lose an electron, to the element that is in the higher position in the periodic table and is more likely to gain an electron.The number of electrons transferred is determined by the difference in the number of electrons needed to fill the valence shells of the two atoms. For example, if one atom has two valence electrons and another atom has six valence electrons, then four electrons would need to be transferred in order for the two atoms to fill their valence shells and form an ionic compound.Once the electrons have been transferred, the resulting ions are held together by the electrostatic force of attraction between the positively charged ions and negatively charged ions. This creates a strong bond between the ions, forming a stable compound.What are ionic compounds?Ionic compounds are formed when one atom loses one or more electrons and another atom gains the same number of electrons. The atom that loses electrons is called a cation, and the atom that gains electrons is called an anion.
The cation and anion are attracted to each other by the electrostatic force of attraction between opposite charges, resulting in the formation of a stable compound.
Ionic compounds can be formed by both metals and nonmetals, but typically occur between a metal and a nonmetal. Metals tend to lose electrons easily and form cations, while nonmetals tend to gain electrons easily and form anions. The electron transfer process is driven by the desire of both atoms to fill their valence shells and achieve a stable electron configuration.

If methyl alcohol boils at 84 %H, what is its boiling point on the Jekyll scale? Express your answer using two significant figures
Methyl alcohol boils at 84 %H, the boiling point of methyl alcohol on the Jekyll scale is -188 %H.
The Jekyll scale is a temperature scale used to express the boiling points of liquids in terms of the percentage of sulfuric acid required to lower the boiling point of the liquid to that of water.
To convert from the boiling point in degrees Celsius to the Jekyll scale, we use the following formula:
= %H
= (100 - 4.6 * (boiling point in °C - 20))
So to convert 84 °C to the Jekyll scale, we can substitute into the above formula:
= %H
= (100 - 4.6 * (84 - 20))
= (100 - 4.6 * 64)
= (100 - 288)
= -188%H

The H+ ions concentration in a 0.10 M HF solution that is 8.4% ionized is 0.0084 M.
Describe ionization of hydrofluoric acid (HF).The ionization of a weak acid, such as hydrofluoric acid (HF), can be described by the following equilibrium:
HF(aq) <=> H+(aq) + F-(aq)
The equilibrium constant for this reaction is known as the acid dissociation constant (KA) and can be used to calculate the H+ ion concentration in a solution of a weak acid.
The percent ionization of a weak acid is defined as the ratio of the concentration of H+ ions at equilibrium to the initial concentration of the acid, multiplied by 100.
In this case, the percent ionization of the 0.10 M HF solution is 8.4%. Therefore:
(H+ ion concentration at equilibrium/initial concentration of HF) * 100 = 8.4%
Hence, the H+ ion concentration at equilibrium is (8.4/100) * 0.10 M = 0.0084 M
