The specific surface area per mL is 251 m²/mL, and the specific surface area per gram is 251 m²/g.

To calculate the specific surface area per mL and per gram accurately, we need to consider the dimensions and units properly.

Given:

Granule size: 5 micrometers

Density: 2 g/mL

First, let's calculate the surface area of a single granule. The surface area of a sphere is given by the formula:

Surface area = 4πr²

where r is the radius of the sphere.

The radius of a granule is half of its diameter, so the radius would be 2.5 micrometers (0.0025 mm).

Surface area of a single granule = 4π(0.0025 mm)² = 4π(6.25 × 10^(-9) mm²) = 3.14 × 10^(-8) mm²

Next, let's calculate the number of granules in 1 mL and 1 gram of the sample.

1 mL of the sample has a volume of 1 mL, and since the density is 2 g/mL, the mass of 1 mL of the sample is 2 grams.

Number of granules in 1 mL = (1 mL / 5 micrometers)^3

= (1 mL / (5 × 10^(-3) mm))^3

= (1 × 10^6 mm³ / (5 × 10^(-3) mm))^3

= (2 × 10^5)^3 = 8 × 10^15 granules

Number of granules in 1 gram = (1 gram / 2 grams) × (1 mL / 5 micrometers)^3

= (1 × 10^3 mm³ / (5 × 10^(-3) mm))^3

= (2 × 10^5)^3

= 8 × 10^15 granules

Finally, we can calculate the specific surface area per mL and per gram:

Specific surface area per mL

= Surface area of a single granule × Number of granules in 1 mL

= 3.14 × 10^(-8) mm² × 8 × 10^15

= 2.51 × 10^8 mm²

Specific surface area per gram = Surface area of a single granule × Number of granules in 1 gram = 3.14 × 10^(-8) mm² × 8 × 10^15 = 2.51 × 10^8 mm²

To convert the specific surface area from mm² to m², we divide by 10^6:

Specific surface area per mL = 2.51 × 10^8 mm² / 10^6 = 251 m²/mL

Specific surface area per gram = 2.51 × 10^8 mm² / 10^6 = 251 m²/g

Therefore, the specific surface area per mL is 251 m²/mL, and the specific surface area per gram is 251 m²/g.

Adding Na3PO4(s) will introduce more PO4^3- ions into the solution, which will react with H3O+ ions to form more H3PO4 and H2O through the reverse reaction. This will shift the equilibrium to the left, decreasing the concentration of H3O+ ions and increasing the concentration of H3PO4 and H2O. Therefore, the concentration of H3O+ ions will decrease, and the correct answer is (C) H3O+.

The absence of attractive or repulsive forces between gas molecules means that they are free to move independently and randomly. This results in the motion of gas particles being characterized by constant collisions and changes in direction and speed. Without any forces to constrain their movement, gas particles will continue to move until they collide with other particles or the walls of their container. This is what causes gases to fill up any container they are in, as their independent motion allows them to spread out evenly throughout the available space.

What is attractive force?

An attractive force is a force that pulls or draws two or more objects or particles towards each other. It is the opposite of a repulsive force, which pushes objects or particles away from each other.

Attractive forces can be observed in a variety of contexts, including gravity, electromagnetism, and intermolecular forces in chemistry. For example, the force of gravity between two objects is an attractive force that pulls them together, while the electromagnetic force between opposite charges is also an attractive force.

What is repulsive force?

A repulsive force is a force that pushes two or more objects or particles away from each other. It is the opposite of an attractive force, which pulls objects or particles towards each other.

Repulsive forces can be observed in a variety of contexts, including electromagnetism and intermolecular forces in chemistry. For example, the force between two like charges is repulsive, while the force between two like magnetic poles is also repulsive.

To explain how hybrid orbitals are formed on the sulfur (S) atom in SOCl2, we need to first draw the orbital diagram of S, focusing on the valence electrons.

Sulfur (S) has the electron configuration [Ne] 3s2 3p4. The valence shell of sulfur consists of 6 electrons, with 2 in the 3s orbital and 4 in the 3p orbitals. In order to form hybrid orbitals, the 3s and 3p orbitals of sulfur will combine to create a set of new hybrid orbitals.

To determine the number and type of hybrid orbitals, we count the number of electron groups around the sulfur atom, which includes both lone pairs and bonded atoms. In SOCl2, there are 4 electron groups around sulfur: one sulfur-chlorine double bond, and two lone pairs.

Since there are 4 electron groups, sulfur undergoes sp3 hybridization. This means that the 3s orbital and the 3p orbitals (3px, 3py, and 3pz) will hybridize, resulting in four sp3 hybrid orbitals. These hybrid orbitals are oriented in a tetrahedral arrangement around the sulfur atom.

The new sp3 hybrid orbitals will then form sigma bonds by overlapping with the appropriate atomic orbitals of the surrounding atoms (oxygen and chlorine) in the molecule SOCl2. This allows for the formation of the molecular structure and the bonding in the compound.

In probability theory and measure theory, a σ-algebra is a collection of subsets of a given set Ω that satisfies certain properties. The notation σ(A,B) represents the smallest σ-algebra that contains both subsets A and B. This means that σ(A,B) consists of all possible subsets that can be formed by taking the union, intersection, and complement of sets in A and B.

To understand this concept better, let's consider an example. Suppose we have a set Ω = {1, 2, 3, 4} and two subsets A = {1, 2} and B = {2, 3}. The σ-algebra σ(A,B) would include the empty set, the set Ω itself, as well as other subsets such as {1}, {2}, {3}, {1, 2}, {2, 3}, and {1, 2, 3}. It would also include their complements, for example, the complement of {1} would be {2, 3, 4}.

The solubility product constant for CuI where solubility of CuI is \(2*10^{-6}\) molar is  \(4 * 10^{-12}\).

The solubility of CuI is 2 x 10^-6 M. To find the solubility product constant (Ksp) for CuI, we need to consider its dissociation in water:
CuI(s) ⇌ Cu⁺(aq) + I⁻(aq)
Since the solubility is 2 x 10^-6 M, the concentrations of both Cu⁺ and I⁻ ions are equal to\(2*10^{-6}\) M. The Ksp is calculated as the product of the concentrations of the ions:
Ksp = [Cu⁺] * [I⁻]
Substitute the given solubility values:
\(Ksp = (2 *10^-6) * (2 *10^-6)\)
\(Ksp = 4 * 10^{-12}\)
So, the solubility product constant (Ksp) for CuI is \(4 * 10^{-12.\)

The entropy of 1 mole of N2 molecules, considered as an ideal gas occupying a cubic volume of side 1 cm, is approximately 4:  62 J/K.

To find the entropy of 1 mole of N2 molecules, we need to use the formula for entropy:

S = R * ln(W)

Where:
S is the entropy
R is the gas constant
ln is the natural logarithm
W is the number of microstates or ways the system can be arranged

For an ideal gas, the number of microstates can be calculated using the formula:

W = (V^N) / (N!)

Where:
V is the volume
N is the number of molecules

Given that we have 1 mole of N2 molecules, which is approximately 6.022 x 10^23 molecules, and the volume of the cube is 1 cm^3, we can calculate the entropy.

First, let's convert the volume from cm^3 to m^3:

1 cm^3 = (1 x 10^-2 m)^3 = 1 x 10^-6 m^3

Now, we can substitute the values into the formula for W:

W = ((1 x 10^-6 m^3)^(6.022 x 10^23)) / (6.022 x 10^23)!

To simplify the calculation, we can use the fact that ln(W) is equivalent to ln((V^N) / (N!)) = ln(V^N) - ln(N!).

ln(W) = ln((1 x 10^-6 m^3)^(6.022 x 10^23)) - ln(6.022 x 10^23)!

ln(W) = (6.022 x 10^23) * ln(1 x 10^-6 m^3) - ln(6.022 x 10^23)!

Now, substituting the values of ln(1 x 10^-6 m^3) and ln(6.022 x 10^23) into the equation:

ln(W) = (6.022 x 10^23) * (-13.8155) - ln(6.022 x 10^23)!

Finally, we can use the value of the gas constant, R, which is approximately 8.314 J/(mol·K), to calculate the entropy:

S = R * ln(W) = (8.314 J/(mol·K)) * ((6.022 x 10^23) * (-13.8155) - ln(6.022 x 10^23)!)

Explanation:

The amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.

To calculate the molarity of Kool Aid desired, we need to determine the number of moles of Kool Aid powder and sugar in the package. Since the molecular formula for sugar is C12H22O11, we can calculate its molar mass as follows:

Molar mass of C12H22O11 = (12 * 12.01) + (22 * 1.01) + (11 * 16.00)

= 144.12 + 22.22 + 176.00

= 342.34 g/mol

Given that the package contains 4.25 grams of Kool Aid powder, we can calculate the number of moles of Kool Aid powder using its molar mass:

Number of moles of Kool Aid powder = Mass / Molar mass

= 4.25 g / 342.34 g/mol

≈ 0.0124 mol

Similarly, for the sugar, which has a molar mass of 342.34 g/mol, we can calculate the number of moles of sugar using its mass:

Number of moles of sugar = Mass / Molar mass

= 192.00 g / 342.34 g/mol

≈ 0.5612 mol

Now, to calculate the molarity of the desired Kool Aid solution, we need to determine the volume of water. Given that 1.06 quarts is equal to 1 liter, and we have 2.00 quarts of water, we can convert it to liters as follows:

Volume of water = 2.00 quarts * (1.06 liters / 1 quart)

= 2.12 liters

To find the molarity, we use the formula:

Molarity (M) = Number of moles / Volume (in liters)

Molarity of Kool Aid desired = (0.0124 mol + 0.5612 mol) / 2.12 L

≈ 0.286 M

To prepare 65 mL of the desired molarity, we can use dilution calculations. We need to determine the volume of concentrated solution and the volume of water needed.

Let's assume the concentration of the concentrated Kool Aid solution is C M. Using the dilution formula:

(C1)(V1) = (C2)(V2)where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

Given that C1 = C M and V1 = V mL, and we want to prepare a final volume of 65 mL (V2 = 65 mL) with a final concentration of 0.286 M (C2 = 0.286 M), we can rearrange the formula to solve for the volume of the concentrated solution:

(C M)(V mL) = (0.286 M)(65 mL)

V mL = (0.286 M)(65 mL) / C M

So, the amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.
