HCl is the most polar due to the high electronegativity of Cl.

Hydrogen chloride is a diatomic molecule, composed of a hydrogen atom, H, and a chlorine atom, Cl, joined by a polar covalent bond. The bond is a polar covalent bond because the chlorine atom is much more electronegative than the hydrogen atom.

Positively charged protons in the nucleus attract negatively charged electrons. As the number of protons in the nucleus increases, the electronegativity, or attractive force, increases. Therefore, electronegativity increases in a row from left to right on the periodic table.

4 ATP molecules are directly generated in the Krebs cycle when 2 molecules of glucose are oxidized

The Krebs cycle,  TCA cycle or the citric acid cycle, is a series of enzyme-catalyzed reactions occurring  in the mitochondrial matrix and involves the oxidation of acetyl-CoA.

The acetyl group of acetyl-CoA is oxidized to make two molecules of CO2 in a succession of eight steps, while also producing one ATP. Additionally, reduced high-energy molecules like NADH and FADH2 are created.

Each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must  move twice for one glucose molecule to produce the four CO2, six NADH, two FADH2, and two ATPs.

The energy of a photon can be calculated using the formula: E = hν = hc/λ, where E is the energy, h is Planck's constant (6.626 x 10^-34 Js), ν is the frequency, c is the speed of light (2.998 x 10^8 m/s), and λ is the wavelength which is 6.53 x 10^-38 kJ/mol

Part A: ν = 5.95 x 10^19 s^-1

E = hν = (6.626 x 10^-34 Js) x (5.95 x 10^19 s^-1) = 3.948 x 10^-14 J/photon

The solubility of AgCN in a solution containing 1.0M H Ksp of AgCN is 2.2e-12 Ka of HCN is 6.2e-10 is 5.9 x 10^-2M.

Given concentration of H+ (M) = 1.0M

Ksp of AgCN = 2.2e-12

Ka  of HCN = 6.2e-10

AgCN ⇋ Ag+ +CN− ................Ksp

CN − + H+ ⇋ HCN................... 1/Ka​

AgCN + H+ ⇋ HCN + Ag+ ...................Ksp/Ka = K0

K0 = 2.2e-12/6.2e-10 = 0.0035 = 35 x 10-4

At Equilibrium:   AgCN + H+ ⇋ HCN + Ag+

Let the moles of [Ag+] = x

So the number of moles of [HCN] = x

K0 = [Ag+] [HCN] / [H+]

35 x 10-4 = x^2/1

x = 5.9 x 10^-2M

Hence the molar solubility of AgCN in buffer solution is 5.9 x 10^-2M.

The bulk of ATP production occurs during cellular respiration within the mitochondrial matrix, producing around thirty-two ATP molecules for every molecule of oxidized glucose.

The energy currency of the cell is ATP (adenosine triphosphate). It is a natural chemical molecule made up of phosphate groups, adenine, and the sugar ribose. These molecules supply energy to the body's many metabolic operations. Therefore, it is dubbed "Energy Currency of the Cell". ATP can be utilized to store energy for future reactions or it can be used to pay for reactions when the cell need energy. Animals use ATP to store the energy received from food breakdown.

The precipitate is collected, filtered, dried, and weighed.. The mass of the precipitate is 0.116 g.

Dissolved refers to a solute that is completely dissolved in a solvent, resulting in a homogeneous mixture. When a solute, such as a salt, is dissolved in a solvent, such as water, the molecules of each component are dispersed evenly throughout the mixture. This process can be reversed by evaporating the solvent, leaving the solute behind. The amount of solute that can be dissolved in a particular solvent is known as its solubility.

When ocean water that is more dense (colder or saltier) is mixed with water that is less dense (warmer or less salty), the denser water will sink to the bottom and the less dense water will rise to the top. This is known as stratification, and it helps to create distinct layers in the ocean.

This stratification can create an environment that is more conducive to life, as it allows different types of organisms to inhabit different layers of the ocean.

The different layers of the ocean created by stratification play a significant role in the global climate system. Colder, denser waters are usually found at the bottom of the ocean, while warmer, less dense waters are found near the surface.

This temperature difference creates a natural convection system that drives currents throughout the ocean, which helps to regulate temperatures on a global scale. Additionally, stratification can also affect the amount of oxygen in the ocean.

The ratio of effusion rates of Sulphur dioxide and methane is 0.5

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

Rate of Diffusion ∝ 1 ÷ √molar mass of the gas

We are given:

Molar mass of Sulphur dioxide = 64.066 g/mol

Molar mass of methane = 16.04 g/mol

By taking their ratio, we get:

Rate of SO₂ ÷ Rate of CH₄ = √MCH₄ ÷ √MSO₂

Rate of SO₂ ÷ Rate of CH₄ = √16.04 ÷ √64.066

Rate of SO₂ ÷ Rate of CH₄ = 0.5

Hence, the ratio of rate of effusion of Sulphur dioxide and methane will be 0.5

Electrons stay in between the nuclei of the two hydrogen atoms because they are attracted to the positive charge of the nuclei.

Electrons are negatively charged species, so they are attracted towards the positive charge of a nucleus.
