Generally, such a solid is classified as c. molecular. A solid that is soft, a poor conductor of heat and electricity, and has a low melting point is typically classified as a molecular solid.

This is because molecular solids consist of discrete molecules held together by relatively weak intermolecular forces such as London dispersion forces, dipole-dipole forces, and hydrogen bonding. These forces are much weaker than the ionic or covalent bonds that hold together ionic or covalent network solids, respectively, which results in lower melting and boiling points, and softer physical properties.

The molar mass of the ideal gas is 112 g/mol (option a).

To determine the molar mass of the gas, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. Rearranging the equation to solve for n, we have n = PV / RT.

First, we need to convert the given values to SI units. The volume is 200 ml, which is equal to 0.2 L. The temperature is 50.0 °C, which is equal to 323.15 K. The pressure is 720 mm Hg, which is equal to 0.947 atm. The gas constant R is 0.0821 L·atm/(mol·K).

Now, we can substitute the values into the equation: n = (0.947 atm)(0.2 L) / (0.0821 L·atm/(mol·K))(323.15 K). Solving for n, we get n ≈ 0.111 mol.

Finally, we can calculate the molar mass by dividing the mass (0.800 g) by the number of moles (0.111 mol), giving us 7.21 g/mol. Rounding to the nearest whole number, the molar mass is approximately 112 g/mol(A).

Based on Lewis structures, the ordering of N-O bond lengths is NO+ < NO2- < NO3-.

In Lewis structures, the number of electron pairs around the central atom can affect the bond lengths. The more electron pairs there are, the greater the repulsion between them, which can lead to longer bond lengths.

In NO+, there are two electron pairs around the central nitrogen atom, resulting in a linear structure. The N-O bond length in NO+ is shorter compared to the other two molecules.

In NO2-, there are three electron pairs around the central nitrogen atom, resulting in a bent structure. The presence of an additional lone pair increases the electron-electron repulsion, leading to longer N-O bond lengths compared to NO+.

In NO3-, there are four electron pairs around the central nitrogen atom, resulting in a trigonal planar structure. The presence of two additional lone pairs further increases the repulsion, resulting in the longest N-O bond lengths among the three molecules.

A photon is a fundamental particle of light and other forms of electromagnetic radiation. It is the smallest discrete unit of electromagnetic energy and behaves both as a particle and a wave. Photons carry energy, momentum, and angular momentum.

The correct explanation is The photons emitted by the red source have less energy than the green source because they have a lower frequency. The energy of a photon is directly proportional to its frequency, as given by the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency. Since the red source has a lower frequency than the green source, the energy of the red photons will be lower. The wattage of the source, which is a measure of the power or rate of energy transfer, does not directly affect the energy of individual photons. It relates to the total amount of energy emitted by the source per unit of time.

The reasons sulfuric acid is used instead of pure water in a reaction are: 1) sulfuric acid acts as an electrolyte, increasing water's conductivity, 2) it increases the concentration of protons, accelerating the reaction, and 3) it helps shift the equilibrium constant to a more favorable value.

Sulfuric acid (H2SO4) is commonly used in reactions instead of pure water for several reasons. First, sulfuric acid acts as an electrolyte, enhancing the ability of water to conduct electric current. This is important when the reaction involves the transfer of ions or the participation of charged species.

Second, sulfuric acid increases the concentration of protons (H+) in the solution. The presence of a higher proton concentration can accelerate the reaction by increasing the frequency of successful collisions between reactant molecules, thereby increasing the reaction rate.

Third, sulfuric acid can help shift the equilibrium constant of a reaction to a more favorable value. Increasing the concentration of protons, can drive the reaction toward the desired products and promote a higher yield.

However, it is important to note that sulfuric acid itself does not catalyze the reaction by providing an alternate reaction pathway or participating in the reaction directly. Its role is primarily to provide the aforementioned effects, such as increased conductivity, higher proton concentration, and favorable equilibrium conditions.

Intermolecular forces originate from the interactions between molecules, and these interactions arise from the electric charges of atoms and molecules.

The electron clouds around the atoms and molecules are constantly in motion, and as they move, they create temporary dipoles or partial charges. These temporary dipoles or partial charges attract or repel other nearby molecules or atoms, creating intermolecular forces.

There are three primary types of intermolecular forces: London dispersion forces, dipole-dipole interactions, and hydrogen bonding.

London dispersion forces are the weakest intermolecular force and arise from the temporary dipoles created by the electron cloud movement.

Dipole-dipole interactions occur between molecules that have a permanent dipole moment, meaning they have a partial positive and partial negative charge on different ends of the molecule.

Hydrogen bonding is a type of dipole-dipole interaction that occurs between molecules with a hydrogen atom bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine.

The strength of intermolecular forces depends on several factors, including the size and shape of the molecules, the strength of the molecular dipole moments, and the polarity of the molecules.

An atom is the fundamental unit of matter that is made up of a nucleus containing protons and neutrons with electrons orbiting around the nucleus. The best description of an atom's physical structure is "atoms are little bubbles of space with mass concentrated at the center of the bubble.

"An atom is made up of subatomic particles which include protons, neutrons, and electrons. The protons and neutrons are found in the nucleus of the atom which is situated at the center. The nucleus is positively charged because of the protons and contains almost all of the mass of the atom. Electrons, on the other hand, orbit around the nucleus in shells and subshells and they have a negative charge.An atom can be visualized as a tiny, hard, solid sphere, but this description is not entirely accurate. Atoms are mostly made up of empty space, with the electrons orbiting around the nucleus. It is possible to consider an atom as a tiny bubble of space with a nucleus at its center. The electrons are located at different levels and are continuously moving around the nucleus in a cloud-like region.A good analogy for an atom is that it's like a mini-solar system, with the nucleus being the sun and the electrons being the planets orbiting around it.

The density of a sample of argon gas at 60 ∘C and 858 mmHg is 1.65 g/L..

To calculate the density of a gas sample, we can use the ideal gas law equation:

PV = nRT,

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

To convert the given temperature of 60 °C to Kelvin, we add 273.15:

T = 60 °C + 273.15 = 333.15 K.

Given:

Temperature (T) = 333.15 K,

Pressure (P) = 858 mmHg.

First, we need to convert the pressure from mmHg to atm since the ideal gas constant (R) has units of atm·L/(mol·K). There are 760 mmHg in 1 atm, so:

P = 858 mmHg / 760 mmHg/atm ≈ 1.129 atm.

To find the density, we need to rearrange the ideal gas law equation to solve for density (ρ):

ρ = (P * M) / (RT),

where M is the molar mass of argon gas (approximately 39.95 g/mol).

Plugging in the values, we have:

ρ = (1.129 atm * 39.95 g/mol) / (0.0821 atm·L/(mol·K) * 333.15 K),

Calculating this expression gives us:

ρ ≈ 1.65 g/L.

The standard enthalpy change (ΔH°) for the given reaction is -580 kJ/mol. This indicates that the reaction is exothermic, meaning that heat is released during the reaction.

The standard enthalpy change (ΔH°) for the reaction can be calculated using the following formula:

ΔH° = ΣnΔH°f(products) - ΣnΔH°f(reactants)

where n is the stoichiometric coefficient of each substance and ΔH°f is the standard heat of formation for each substance.

Given the heats of formation, the equation becomes:

ΔH° = 2(ΔH°f(C) + ΔH°f(D)) - 2ΔH°f(A) - ΔH°f(B)

Substituting the values of the heats of formation:

ΔH° = 2(213 kJ/mol + (-503 kJ/mol)) - 2(-227 kJ/mol) - (-399 kJ/mol)

A non-reducing disaccharide is formed when a glycosidic bond occurs between two monosaccharides, both of which are in the ketose form. Specifically, a glycosidic bond between two ketose monosaccharides in the α-anomeric form would yield a non-reducing disaccharide.

In the α-anomeric form of a ketose, the anomeric carbon (the carbon involved in the glycosidic bond formation) is in the α configuration. The α configuration means that the hydroxyl group attached to the anomeric carbon is pointing downward. When two α-ketose monosaccharides are linked together through a glycosidic bond, the resulting disaccharide is non-reducing because the anomeric carbon of both monosaccharides is involved in the glycosidic bond and cannot undergo mutarotation.

In contrast, if the glycosidic bond occurs between a ketose and an aldose (such as a ketose and a glucose), or between a ketose and the reducing end of another carbohydrate molecule, the resulting disaccharide would be a reducing disaccharide because the anomeric carbon of the reducing monosaccharide can still undergo mutarotation and reduce other compounds.

8S8(s) + 2NO3^-(aq) + 10H+(aq) → 8SO2(g) + 2NO(g) + 5H2O(l)

To balance the oxidation-reduction reaction in acidic solution:

Step 1: Split the reaction into two half-reactions, one for oxidation and one for reduction.

Oxidation half-reaction:

S8(s) → SO2(g)

Reduction half-reaction:

NO3^-(aq) → NO(g)

Step 2: Balance the atoms in each half-reaction.

Oxidation half-reaction (Sulfur):

Since there are eight sulfur atoms on the left side and only one on the right side, we need to add 7 water (H2O) molecules to balance the number of oxygen atoms.

S8(s) → 8SO2(g)

Now, balance the sulfur atoms by adding 8 electrons (e^-) to the left side:

S8(s) + 8e^- → 8SO2(g)

Reduction half-reaction (Nitrate):

Balance the nitrogen and oxygen atoms by adding water (H2O) and hydrogen ions (H+) to the right side:

2NO3^-(aq) + 10H+(aq) → 2NO(g) + 5H2O(l)

Add electrons (e^-) to the left side to balance the charges:

2NO3^-(aq) + 10H+(aq) + 8e^- → 2NO(g) + 5H2O(l)

Step 3: Balance the electrons in both half-reactions.

Multiply the oxidation half-reaction by 8 and the reduction half-reaction by 1 to equalize the number of electrons in both half-reactions:

8(S8(s) + 8e^- → 8SO2(g))

2(NO3^-(aq) + 10H+(aq) + 8e^- → 2NO(g) + 5H2O(l))

Step 4: Add the half-reactions together.

8S8(s) + 2NO3^-(aq) + 10H+(aq) → 8SO2(g) + 2NO(g) + 5H2O(l)

The balanced oxidation-reduction reaction in acidic solution is:

K = [Cu₂⁺] * [OH⁻]² / [Cu]² * [O₂]

In this expression, the square brackets denote the concentration of each species at equilibrium.

[Cu₂⁺] represents the concentration of Cu²⁺ ions, which are the product of the reaction.

[OH⁻] represents the concentration of hydroxide ions, which are also products of the reaction. The exponent of 2 indicates that two OH⁻ ions are involved in the reaction.
