In a homologous series of organic compounds, the most reduced type is Alkane. Therefore, the correct answer is option B.

A homologous series is a group of organic compounds that have similar structures and properties but differ by a constant unit, usually a CH2 group. In terms of oxidation state, alkanes are the most reduced, meaning they have the least amount of oxygen atoms bonded to the carbon atoms. Carboxylic acids, alcohols, aldehydes, and ketones all have a higher oxidation state, meaning they have more oxygen atoms bonded to the carbon atoms. Therefore, alkanes are the most reduced in a homologous series of organic compounds.

The most reduced type of organic compound in a homologous series is B. Alkane.

A homologous series is a group of organic compounds that have the same functional group and similar chemical properties but differ in the number of carbon atoms in their carbon chain. The most reduced type of organic compound is the one with the greatest number of hydrogen atoms bonded to the carbon atoms.

Alkanes are the most reduced type of organic compound because they have the maximum number of hydrogen atoms bonded to the carbon atoms. Alkanes have the general formula CₙH2₂ₙ₊₂, where n is the number of carbon atoms. This means that for every carbon atom, there are two hydrogen atoms bonded to it, plus two additional hydrogen atoms.

Carboxylic acids, alcohols, aldehydes, and ketones all have fewer hydrogen atoms bonded to the carbon atoms than alkanes do. This is because they have functional groups that contain oxygen atoms, which replace some of the hydrogen atoms. Therefore, the most reduced type of organic compound in a homologous series is B. Alkane.

When copper sulphate crystals are introduced to water, the particles lose their attraction to one another and begin to move constantly, becoming mixed with the water. White is pure copper(II) sulphate. Because it contains no water, it is also known as anhydrous copper(II) sulphate.

A sample of copper(II) sulphate becomes blue when water is present. Because the individual water molecules are retained within the ionic lattice around the copper(II) ions, it remains a dry solid. Copper(II) sulphate solutions are also blue.

This shift in colour can be utilised to identify the presence of water (or water vapour).

The standard potential for the given galvanic cell is +1.06 V.

To calculate the standard potential for the given galvanic cell, we need to determine the individual reduction potentials of the half-reactions and then subtract the potential of the anode (where oxidation occurs) from the potential of the cathode (where reduction occurs).

Given reduction half-reaction potentials:

Ag+(aq) + e^− → Ag(s): E∘ = +0.80 V

Ni2+(aq) + 2e^− → Ni(s): E∘ = -0.26 V

Since we have the reduction potentials for both half-reactions, we can directly calculate the standard potential for the cell:

E∘(cell) = E∘(cathode) - E∘(anode)

= E∘(Ag+(aq) + e^− → Ag(s)) - E∘(Ni2+(aq) + 2e^− → Ni(s))

E∘(cell) = +0.80 V - (-0.26 V)

Answer:

27.19 cm.

Explanation:

From the question given above, the following data were obtained:

Height (h) of cylinder = 6461.76 cm

Volume (V) of cylinder = 15000000 cm³

P1 (π) = 3.14

Radius (r) =.?

Thus, we can obtain the radius of the cylinder water tank by using the following formula as illustrated below:

V = πr²h

15000000 = 3.14 × r² × 6461.76

15000000 = 3.14 × 6461.76 × r²

Divide both side by 3.14 × 6461.76

r² = 15000000 / (3.14 × 6461.76)

Take the square root of both side

r = √[15000000 / (3.14 × 6461.76)]

r = 27.19 cm

Thus, the radius of the cylinder water tank is 27.19 cm.

Answer: Approximate radius of an iron atom ≈ 5.77 × 10^-15m or 0.0577 nm

(a) Impact parameter refers to the perpendicular distance between the path of an incident particle and the center of the target.

Let’s compute the impact parameter using the formula below:

b = cot(θ/2) * (R1 + R2),

where θ = scattering

angle = 95°,

R1 = radius of incident particle,

R2 = radius of target particle

R1 = r, radius of alpha particle

R2 = R, radius of iron atom

R = 1.2 × 10^-10mb = cot(θ/2) * (R1 + R2)

b = cot(95°/2) * (1.2 × 10^-10m + 8.5 × 10^-15m)

b = 3.556 × 10^-15m ≈ 4 μm

Answer: Impact parameter = 4 μm

(b) Scattering occurs when the impact parameter is less than the distance of closest approach (DCA).

Therefore, we need to compute DCA using the formula below:

DCA = 2R(R1 + R2) / (R + R1)sin²(θ/2)

DCA = 2(1.2 × 10^-10m)(17 × 10^-6m + 1.2 × 10^-10m) / (8.5 × 10^-15m + 1.2 × 10^-10m)sin²(95°/2)

DCA = 3.28 × 10^-13m

To determine the fraction of particles scattered at angles greater than 95°,

we need to compute the area of the ring centered at the point of closest approach, but outside of the minimum scattering angle.

The area of this ring is πb² (1 - cos(θ/2)).

Also, the total area of scattering is πDCA² / 4.

Therefore, the fraction of particles scattered at angles greater than 95° is:Fraction = πb² (1 - cos(θ/2)) / πDCA² / 4

Fraction = (4b² / DCA²) (1 - cos(θ/2))

Fraction = (4(4 × 10^-12m²) / (3.28 × 10^-13m)²) (1 - cos(95°/2)) ≈ 0.038

Answer: Fraction of particles scattered at angles greater than 95° ≈ 0.038

(c) To compute the approximate radius of an iron atom, we need to use the formula for the radius of the nucleus of an atom. The Rutherford scattering formula, which is based on Coulomb's law, was used to determine the size of the nucleus of the atom.

Rutherford's formula states that the radius of the nucleus is R = R0A¹/³,

where

A is the mass number of the nucleus,

R0 is the radius of the nucleus of hydrogen (which is about 1.2 × 10^-15m), and

R is the radius of the nucleus of the atom.

Therefore, we need to determine the mass number of iron. The mass number of an atom is equal to the number of protons (atomic number) plus the number of neutrons. The atomic number of iron is 26, and the atomic mass is 56. Thus, the mass number is 56.

R = R0A¹/³R = (1.2 × 10^-15m)(56)¹/³ ≈ 5.77 × 10^-15m

Answer: Approximate radius of an iron atom ≈ 5.77 × 10^-15m or 0.0577 nm

The total charge that flows while the battery is being charged is approximately 193,939.39 Coulombs.

To calculate the total charge that flows while the battery is being charged, we can use the relationship between electrical energy, potential difference, and charge.

The electrical energy (E) stored in the battery is given as 64 mega Jules (64 MJ). The potential difference (V) provided by the battery is 330 volts. We know that the energy (E) is equal to the product of the potential difference (V) and the charge (Q):

E = V * Q

Since the charging process is 100% efficient, all the electrical energy supplied is stored in the battery. Therefore, we can rearrange the equation to solve for the charge (Q):

Q = E / V

Substituting the given values, we have:

Q = 64 MJ / 330 V

To perform the calculation, we need to convert mega Jules (MJ) to joules (J) since the SI unit of energy is joules. One mega Joule is equal to 1 million joules:

Q = (64 * 10^6 J) / 330 V

Calculating the division:

Q ≈ 193,939.39 Coulombs

Therefore, the total charge that flows while the battery is being charged is approximately 193,939.39 Coulombs.

This value represents the quantity of electric charge transferred during the charging process, and it indicates the amount of electricity that enters the battery.

The gases hydrogen and helium explains that the more the dense the gases are the more the large are the planets so terrestrial planets are smaller than the gas giants.

The Sun, a G2 main-sequence star that makes up 99.86% of the Solar System's known mass and dominates it gravitationally, is the dominant body of the system. The remaining mass is made up entirely of the big planets, the Sun's four largest circling entities, with Jupiter and Saturn making up more than 90% of it.

When comparing the sizes of terrestrial planets with gas giant planets, information regarding the solar system's composition is quite useful.

The size differences occur between the terrestrial planets and the gas giants due to the presence of different concentration of gases in their compositions. Gas giants planets are also called the outer planets which are made up of gases.

While they are big, they are less dense and have more moons than terrestrial planets, which have stony surfaces. The inner planets is another name for them. We may infer that there are significant size disparities between the terrestrial planets and the gas giants since they are smaller and more dense than gas giant planets, have fewer moons, or none at all.

Disposed of.... etc.

Fractional distillation is a technique used to separate mixtures of liquids with different boiling points.

The mixture is heated in a flask and the vapors are collected and condensed into separate fractions. Each fraction corresponds to a different boiling point and therefore a different component of the mixture.

The volumes of each fraction will depend on the composition of the mixture and the efficiency of the distillation process. However, you can expect the volume of fraction 1, which corresponds to the component with the lowest boiling point, to be the largest. This is because the component with the lowest boiling point will vaporize first and therefore be collected in the greatest amount.

The volumes of fractions 2 and 3 will be smaller, as they correspond to components with higher boiling points that will vaporize later in the distillation process. Overall, the volumes of each fraction will depend on the composition of the mixture and the efficiency of the distillation process, but you can expect the volume of fraction 1 to be the largest, followed by smaller volumes for fractions 2 and 3.

According to this question, there are four (4) isotopes for element X with the following relative abundance:

Isotope 1 = 9.67%, mass no: 38

Isotope 2 = 78.68%, mass no: 39

Isotope 3 = 11.34%, mass no: 40

Isotope 4 = 0.31%, mass no: 41

To find the average atomic mass of element X, we multiply each isotopes' relative abundance by its mass no and find the sum as follows:

We convert each percentage to decimal abundance:

Isotope 1 = 9.67% = 0.0967

Isotope 2 = 78.68% = 0.7868

Isotope 3 = 11.34% = 0.1134

Isotope 4 = 0.31% = 0.0031

(0.0967 × 38) + (0.7868 × 39) + (0.1134 × 40) + (0.0031 × 41)

3.6746 + 30.6852 + 4.536 + 0.1271

An object sliding on a surface eventually stops due to friction.

Friction is a force that opposes motion between two surfaces that are in contact with each other. When an object is sliding on a surface, there is friction between the object and the surface, which acts in the opposite direction to the motion of the object.

Friction is caused by the microscopic irregularities on the surfaces that are in contact with each other. As the object slides along the surface, these irregularities cause interlocking between the object and the surface, which resists the motion of the object.

As an object slides on a surface, the frictional force gradually slows it down until it comes to a stop. The amount of time it takes for an object to stop sliding depends on factors such as the initial speed of the object, the mass of the object, and the strength of the frictional force.

Most enzymes do not work if the temperature is raised too much because enzymes are proteins and their function depends on their shape.

Enzymes have an optimal temperature range at which they function most efficiently. If the temperature is too high, the enzymes can become denatured, which means they lose their shape and function. Additionally, at higher temperatures, the substrate molecules are moving too quickly for the enzymes to bind to them effectively, leading to a decrease in enzyme activity. Therefore, it is essential to maintain a suitable temperature for enzymes to function correctly.

Enzymes are biological molecules that serve as catalysts in a variety of biochemical processes that take place inside of living things. Typically, proteins are responsible for accelerating chemical processes by reducing the activation energy necessary for the reaction to take place. Enzymes attach to particular substrates and transform them into products while staying unaltered. Due to the extreme specificity of each enzyme for a certain substrate or class of substrates, metabolic pathways can be precisely controlled. Numerous physiological processes, such as digestion, cellular respiration, and DNA replication, depend heavily on enzymes.
