The substance with the highest viscosity among the given options is c) HOCH2CH2CH2CH2OH (1-butanol).

Option c) HOCH2CH2CH2CH2OH, or 1-butanol, has the maximum viscosity of the chemicals provided. The resistance to the flow of a fluid is measured by its viscosity, which is controlled by intermolecular forces, molecular size, and shape. The largest molecular weight in this situation is that of 1-butanol, which also has a somewhat long and flexible carbon chain. Higher viscosity is a result of these properties' contribution to increased intermolecular forces. In comparison to 1-butanol, the other options—(CH3CH2)2CO (acetone), C2H4Cl2 (1,2-dichloroethane), CCl4 (carbon tetrachloride), and C6H14 (hexane)—have lower molecular weights or intermolecular interactions.

The pressure of a gas is 1.2 atm at 300k.  the pressure  at 250k if the gas is in a rigid container is 1.0 atm.

To solve this problem, we can use the combined gas law, which states that:

(P1 * V1) / (T1) = (P2 * V2) / (T2)

where P1 is the initial pressure, V1 is the initial volume (which is constant since the gas is in a rigid container), T1 is the initial temperature, P2 is the final pressure (what we're trying to find), V2 is the final volume (also constant), and T2 is the final temperature.

We can rearrange the equation to solve for P2:

P2 = (P1 * V1 * T2) / (V2 * T1)

Plugging in the given values, we get:

P2 = (1.2 atm * V1 * 250K) / (V2 * 300K)

Since the container is rigid, V1 = V2, so we can cancel those terms:

P2 = (1.2 atm * 250K) / 300K

Simplifying:

P2 = 1.0 atm

Therefore, the pressure of the gas at 250K in a rigid container is 1.0 atm.

The density of water is approximately 1 g/mL. The liquid with a density of 4 g/mL would definitely sink in water since the liquid's density (4 g/mL) is greater than the density of water.

The density of the liquid can be calculated by dividing its mass by its volume. So, the density of the liquid is 4 g/mL (200 g ÷ 50 mL).

Whether the liquid would float on water or not depends on the density of water. If the density of water is less than 4 g/mL, then the liquid would sink in water. However, if the density of water is more than 4 g/mL, then the liquid would float on water. The density of water is approximately 1 g/mL, so the liquid with a density of 4 g/mL would definitely sink in water.

Alternatively, to find the density of the liquid, we will use the formula:

Density = Mass / Volume

Given the mass of the liquid is 200 grams and the volume is 50 milliliters, we can plug these values into the formula:

Density = 200 grams / 50 milliliters = 4 grams per milliliter (g/mL)

Now, to determine if the liquid would float on water, we need to compare its density to that of water. The density of water is approximately 1 g/mL. Since the liquid's density (4 g/mL) is greater than the density of water, it will not float on water, and will instead sink.

1- U(r) has a repulsive region at small r due to electron-electron repulsion, followed by an attractive region at intermediate r due to electron-nucleus attraction, and a negligible potential at large r.

The potential energy, U(r), for a system of two atoms can be represented graphically as a function of the internuclear separation distance, r. At small values of r, the atoms experience repulsion due to the electron-electron interactions, resulting in a steep increase in potential energy. This repulsive region prevents the atoms from getting too close to each other.

As the internuclear separation distance increases, the attractive force between the electrons and the nuclei becomes dominant, leading to a decrease in potential energy. This attractive region is typically characterized by a shallow potential well. At intermediate values of r, the potential energy reaches a minimum, indicating a stable configuration where the atoms are bonded.

2- Bohr's model describes the hydrogen atom as a nucleus with an electron orbiting it in quantized energy levels. Electrons can transition between levels by absorbing/emitting photons with energy given by ΔE = hf. The model has limitations but introduced the concept of discrete energy states in atoms.

The Elution sequence of compounds containing certain functional groups from the fastest to the slowest is hydrocarbons, olefins, ethers, halo carbons, aromatics, ketones, aldehydes, esters, alcohols, amines and acids.

Elution:

Elution in organic and analytic chemistry refers to the process in which one material is extracted from another material by washing it with the help of a solvent.

In an elution sequence, regardless of the polarity of the compounds, the solvent which is more polar, its chemicals elutes faster. Therefore, amending the polarity of the solvent will not change the order of elution of compounds. It might seem contradictory as a polar solvent seems to convey polar compounds beyond the non-polar compounds.

Contemplating the solvents and the chemicals will fight for the stationary phase locations conductive to help us visualize the intention. Slow elution would be created by the molecules which were remained to attach to the stationary phase due to poor ability of a less polar solvent to compete. Molecules and a polar solvent successfully asserted for the stationary phase locations.

The interpretation of the molar masses of hydrogen (H) and oxygen (O) is that they represent the average mass of one mole of each element.

In other words, if you have 6.022 x 10^23 atoms or molecules of hydrogen or oxygen, their combined mass would be equal to the molar mass. Comparing the masses of the gas samples in the two containers, we can consider the molar masses. The molar mass of hydrogen (H) is 2 g/mol, while the molar mass of oxygen (O) is 32 g/mol. Since the molar mass of oxygen is larger than that of hydrogen, for the same number of moles of each gas, the mass of the oxygen gas sample would be greater than the mass of the hydrogen gas sample. This means that a given volume of oxygen gas would be heavier than the same volume of hydrogen gas, assuming equal temperature and pressure.

The equilibrium concentration of HClO₂ is 0.22 M.

When NaF is added to a solution of HClO₂, it will react to form HF and HClO₂ as follows:

NaF + HClO₂ → HF + NaClO₂

The balanced chemical equation shows that 1 mol of NaF reacts with 1 mol of HClO₂ to form 1 mol of HF and 1 mol of NaClO₂.

Therefore, if we add 0.15 mol of NaF to the solution, it will react completely with 0.15 mol of HClO₂.

Before the reaction, the solution contains 0.37 M HClO₂, which corresponds to 0.37 mol/L of HClO₂.

If 0.15 mol of HClO₂ reacts, the remaining concentration of HClO₂ can be calculated as:

[HClO₂] = (moles of HClO₂ remaining) / (volume of solution in L)

moles of HClO₂ remaining = initial moles of HClO₂ - moles of HClO₂ that reacted

initial moles of HClO₂ = 0.37 mol/L x 1.0 L

                                    = 0.37 mol

moles of HClO₂ that reacted = 0.15 mol (since 1 mol of NaF reacts with 1 mol of HClO₂)

moles of HClO₂ remaining = 0.37 mol - 0.15 mol  

                                           = 0.22 mol

volume of solution in L = 1.0 L

Therefore,

[HClO₂] = 0.22 mol / 1.0 L

           = 0.22 M

So the equilibrium concentration of HClO₂ is 0.22 M.
