Classifying Characteristics of Rocks

Electron configurations correspond to an excited state is 1s₂, 2s₂, 3p₁.The electrical configuration 1s₂, 2s₂, 3s₁ demonstrates that the atom is in the excited state.

The distribution of an atom's or molecule's electrons in atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry.

An electron is in an excited state when it momentarily possesses an energy level higher than its ground state. If an electron receives more energy, such as when it absorbs a photon, or packet, of light, or collides with an adjacent atom or particle, it can become excited.

The primary distinction between a system's ground state and excited state is that a system's ground state is any condition in which its electrons are at their lowest potential energy levels, whereas an excited state is any state in which they are at an energy greater than the system's ground state.

Thus option A is correct.

Answer:

Na3Po3 is soluble in water

Sodium phosphite, often referred to as [tex]Na_3PO_3[/tex], is generally considered to be water soluble.

Because the sodium cation (Na+) has a significant affinity for water molecules due to their positive charge, sodium compounds generally have a tendency to be soluble in water. The three sodium ions increase the solubility of [tex]Na_3PO_3[/tex] and make it even more soluble.

The solubility of [tex]Na_3PO_3[/tex]  is similarly affected by the phosphate ion [tex](PO^3^-)[/tex]. Phosphates are normally soluble in water unless they are coupled with cations that generate intractable compounds, like some heavy metal ions. The strong ion-dipole interactions between sodium ions and water molecules can be used to explain why [tex]Na_3PO_3[/tex] is soluble in water.

An element in the same row with roughly half of the atomic mass always has a greater atomic radius.

Atomic radius:  It is the distance between the nucleus and the outermost shell.

Atomic mass: It is the mass or the number of nucleons or protons and neutrons inside an atom.

In a row, the number of protons increase but the number of shells remains constant.

Hence, the positive protons in the nucleus attract electrons with more electrostatic force.

Therefore,  an element in the same row with roughly half of the atomic mass always has a greater atomic radius.

Answer:

Fatty acids

Explanation:

Acetyl coA is a compound vital for the process of cellular respiration in the mitochondria. It is the starting material of the kreb's cycle or TCA cycle, which takes place in the mitochondria. During the metabolism of glucose (glycolysis), a molecule called PYRUVATE is first synthesized before becoming acetyl coA in the mitochondrion.

However, the metabolism of FATTY ACIDS (monomers of lipids) directly gives rise to acetyl coA without first becoming pyruvate. The fatty acids molecule undergo Beta- oxidation to produce acetyl coA, which enters the TCA cycle to continue cellular respiration.

Answer:

higher than 59 c because dipole- dipole interactions in iodine monocholoride are stronger than dispersion forces in bromine

The boiling point is the temperature at which the pressure of the liquid is equal to the vapor pressure. The b.p of iodine monochloride will be higher than 59 °C because dipole-dipole interactions are stronger. Thus, option C is correct.

A dipole-dipole interaction is the type of electrostatic attractive force that exists between the positive and the negative side of the polar molecule. They are strong interactions between polar molecules.

The Iodine monochloride (ICl) has a higher boiling point as compared to bromine as the former is a polar molecule with a dipole-dipole bond. The bromine shows the dispersion forces that are the weakest forces.

The polar molecules have differences in their electronegativities that make them have strong dipole interactions. As a result, will need higher temperatures to break bonds.

Therefore, option C. ICl will need a higher boiling temperature than bromine due to the presence of strong dipole forces.

Answer:

Mass = 9.58 g

Explanation:

Given data:

Mass of Zn = 2g

Theoretical yield of ZnI₂ = ?

Solution:

Chemical equation:

Zn + I₂       →     ZnI₂

Number of moles of Zn:

Number of moles = mass/molar mass

Number of moles = 2g / 65.38 g/mol

Number of moles = 0.03 mol

Now we will compare the moles of Zn and ZnI₂.

                   Zn           :          ZnI₂

                    1             :           1

                  0.03        :         0.03

Mass of ZnI₂:

Mass = number of moles × molar mass

Mass = 0.03 mol × 319.22 g/mol

Mass = 9.58 g
