The Lewis structure of [tex]CCl_4[/tex] shows that it has a tetrahedral molecular geometry. The molecule is nonpolar due to the symmetrical arrangement of the chlorine atoms around the central carbon atom.

The Lewis structure of [tex]CCl_4[/tex], also known as carbon tetrachloride, can be determined by placing the carbon atom at the centre and surrounding it with four chlorine atoms. Each chlorine atom forms a single bond with the carbon atom, resulting in four single bonds in total. The Lewis structure shows that [tex]CCl_4[/tex] has a tetrahedral molecular geometry, where the four chlorine atoms are arranged around the central carbon atom in a three-dimensional tetrahedron.

To determine the polarity of the molecule, we need to consider the electronegativity difference between the atoms. Chlorine is more electronegative than carbon, which means it attracts electrons more strongly. However, since the molecule has a symmetrical arrangement with all four chlorine atoms located at the corners of the tetrahedron, the bond polarities cancel each other out. As a result, [tex]CCl_4[/tex] is a nonpolar molecule.

The relationship between the solubility in water, S, and the solubility product, Ksp, for mercury(I) chloride, which exists as the dimer [tex]Hg_2_2[/tex], is defined by the equilibrium expression [tex]Ksp = 4S^3. T[/tex]

When mercury(I) chloride, [tex]Hg_2Cl_2[/tex], is dissolved in water, it dissociates into two Hg+ ions and two [tex]Cl^-[/tex] ions, resulting in the formation of the dimer. The solubility product expression, Ksp, represents the equilibrium between the dissociated ions and the undissociated dimer. Since the stoichiometry of the balanced equation is 2:2 (2[tex]Hg^+[/tex] ions and 2[tex]Cl^-[/tex]ions), the solubility product expression can be written as [tex]Ksp = [Hg^+]^2[Cl^-]^2[/tex].

However, considering that the dimer [tex]Hg_2_2[/tex] is present in the equilibrium, the concentration of [tex]Hg^+[/tex] ions can be expressed as 2S (twice the solubility), and the concentration of [tex]Cl^-[/tex] ions can be expressed as S (the solubility). Substituting these values into the solubility product expression, we get [tex]Ksp = (2S)^2(S)^2 = 4S^3[/tex].

Therefore, the relationship between the solubility in water, S, and the solubility product, Ksp, for mercury(I) chloride is given by the equation [tex]Ksp = 4S^3[/tex]. This equation indicates that as the solubility increases, the solubility product also increases, following a cubic relationship.

The concentration of ammonia in the solution is 0.266 M.

To determine the concentration of ammonia in the solution, we can use the balanced chemical equation for the reaction between ammonia (NH3) and hydrochloric acid (HCl):

NH3 + HCl → NH4Cl

From the equation, we can see that the stoichiometric ratio between ammonia and hydrochloric acid is 1:1. This means that the moles of hydrochloric acid used in the titration is equal to the moles of ammonia present in the original solution.

First, we need to calculate the number of moles of hydrochloric acid used. Given that 21.4 ml of a 0.114 M HCl solution was needed to titrate a 100.0 ml sample of the solution, we can use the equation:

moles of HCl = volume of HCl (in L) × molarity of HCl

Converting the volume to liters:

volume of HCl = 21.4 ml = 0.0214 L

Substituting the values into the equation:

moles of HCl = 0.0214 L × 0.114 M = 0.0024376 mol

Since the stoichiometric ratio is 1:1, the moles of ammonia in the solution is also 0.0024376 mol.

To calculate the concentration of ammonia, we divide the moles of ammonia by the volume of the solution (100.0 ml = 0.1 L):

concentration of ammonia = moles of ammonia / volume of solution

                       = 0.0024376 mol / 0.1 L

                       = 0.024376 M

                       ≈ 0.266 M

Therefore, the concentration of ammonia in the solution is approximately 0.266 M.

The molalities are:

Part A: Molality of HCl(aq) = 15.08 mol/kg

Part B: Molality of NH3(aq) = 19.66 mol/kg

Part A: Molality of HCl(aq)

Step 1: Calculate the mass of HCl in 100 g of solution.

Mass of HCl = (Weight % / 100) * Mass of solution

Mass of HCl = (33.8 / 100) * 100 g = 33.8 g

Step 2: Calculate the moles of HCl using the molarity.

Moles of HCl = Molarity * Volume of solution (in L)

The volume of solution = Mass of solution / Density of solution

Volume of solution = 100 g / 1.19 g/mL = 84.03 mL = 0.08403 L

Moles of HCl = 11.9 M * 0.08403 L = 0.9984 mol

Step 3: Calculate the molality of HCl.

Molality of HCl = Moles of HCl / Mass of solvent (in kg)

Mass of solvent = Mass of solution - Mass of solute

Mass of solvent = 100 g - 33.8 g = 66.2 g = 0.0662 kg

Molality of HCl = 0.9984 mol / 0.0662 kg = 15.08 mol/kg

Part B: Molality of NH3(aq)

Step 1: Calculate the mass of NH3 in 100 g of solution.

Mass of NH3 = (Weight % / 100) * Mass of solution

Mass of NH3 = (24.5 / 100) * 100 g = 24.5 g

Step 2: Calculate the moles of NH3 using the molarity.

Moles of NH3 = Molarity * Volume of solution (in L)

Volume of solution = Mass of solution / Density of solution

Volume of solution = 100 g / 0.90 g/mL = 111.11 mL = 0.11111 L

Moles of NH3 = 13.4 M * 0.11111 L = 1.486 mol

Step 3: Calculate the molality of NH3.

Molality of NH3 = Moles of NH3 / Mass of solvent (in kg)

Mass of solvent = Mass of solution - Mass of solute

Mass of solvent = 100 g - 24.5 g = 75.5 g = 0.0755 kg

Molality of NH3 = 1.486 mol / 0.0755 kg = 19.66 mol/kg

Hence, the molalities are as follows:

The molality of HCl(aq) is 15.08 mol/kg in Part A.

The central carbon atom in glycine has four atoms and two lone pairs of electrons. Therefore, the electron geometry of the central carbon atom is octahedral, with bond angles of 90°, 180°, and 120°.The next step is to determine the molecular geometry. The molecular geometry in glycine is distorted tetrahedral, with bond angles of 120°.The approximate c-n-h bond angle in glycine is 120°.

Answer: Its a weak base

Explanation: Clicked on that and got the answer right. :)

The image that has been shown has helped us to know that the particles are weak bases. Option A

A chemical species or substance that has a restricted capacity to receive or interact with protons (H+ ions) in a solution is said to be a weak base. Weak bases only partially ionize or interact with water, in contrast to strong bases, which totally breakdown into ions in water and quickly take protons.

Compared to strong bases, weak bases have a lesser affinity for protons and fewer alkaline characteristics. They are frequently identified by the considerably lower concentration of hydroxide ions (OH-) in a solution and their imperfect dissociation equilibrium.

When it comes to basic solutions, the pH of a solution is a measure of how basic or acidic it is. Basic solutions have a pH greater than 7. A stronger base has a higher pH than a weaker base.

To determine which one of the following solutions would be the most basic, we need to find out which of them produces the most OH- ions when dissolved in water.

We will use the following information: HNO2 + H2O ⇌ H3O+ + NO2−HONH2 + H2O ⇌ H3O+ + ONH3H2NNH2 + H2O ⇌ H3O+ + NNH3+NaCN + H2O → Na+ + OH- + HCN.

As you can see, NaCN does not produce any OH- ions, so it cannot be the most basic. NaNO2 produces only a small number of OH- ions since it is a weak base, so it cannot be the most basic either.

HONH2 and H2NNH2 are both stronger bases than NaNO2, but H2NNH2 is the strongest of the three.

This means that the most basic solution would be D) H2NNH2.

Option i. the components form a homogeneous solution is correct statements about miscible liquids.

When we talk about miscible liquids, these are liquids that can mix in any proportion without separating, given that the components form a homogeneous solution.

The following statement about miscible liquids is correct: i. the components form a homogeneous solution.

Let's look at each option one by one:i. The components form a homogeneous solution.

Mixtures of liquids that are completely soluble in each other in all proportions are called miscible liquids.

For example, ethanol and water are miscible in each other.

The mixture of the two will be a homogeneous solution where the two components are completely blended

.ii. The partial pressure of each component is the vapor pressure of the mixture times the components mole fraction.

This statement applies to the Raoult's law for ideal solutions, which holds only for solutions of non-electrolytes.

According to Raoult's law, for an ideal solution, the partial pressure of each component in the vapor phase is equal to the product of the vapor pressure of the pure component and its mole fraction in the solution.

iii. Each component has its own vapor pressure.

This is a statement about immiscible liquids rather than miscible liquids.

In immiscible liquids, the components are not soluble in each other, so each component has its own vapor pressure and forms separate layers when mixed.

In conclusion, the correct statement about miscible liquids is that the components form a homogeneous solution.

The solubility of Ag[tex]_{2}[/tex]S in grams per liter is approximately 5.00×1[tex]0^{-17}[/tex] g/L.

The solubility of Ag[tex]_{2}[/tex]S in grams per liter can be calculated using the value of Ksp for silver sulfide, which is 8.00×1[tex]0^{-51}[/tex].

To calculate the solubility, we need to use the equation for the dissociation of Ag[tex]_{2}[/tex]S in water: Ag[tex]_{2}[/tex]S ⇌ 2Ag+ + S[tex]_{2}[/tex]-

The Ksp expression for this reaction is: Ksp = [Ag+]^2[S2-]

Since Ag[tex]_{2}[/tex]S dissociates into two Ag+ ions and one S[tex]_{2}[/tex]- ion, we can write the solubility of Ag[tex]_{2}[/tex]S as 2x and x for [Ag+] and [S[tex]_{2}[/tex]-] respectively.

Using the value of Ksp, we can set up the equation:

8.00×1[tex]0^{-51}[/tex] = (2x[tex])^{2}[/tex] * x

Simplifying the equation, we get:

4[tex]x^{3}[/tex] = 8.00×1[tex]0^{-51}[/tex]

Solving for x, we find:

x = 5.00×1[tex]0^{-17}[/tex]

Therefore, the solubility of Ag[tex]_{2}[/tex]S in grams per liter is 5.00×1[tex]0^{-17}[/tex] g/L.

The value of ksp for silver sulfide (Ag2S) is 8.00 × 10⁻⁵¹.

The solubility of Ag2S in grams per liter can be determined as follows:

Let x be the solubility of Ag2S in moles per liter. Then the solubility product expression can be written as:

Ksp = [Ag⁺]₂[S²⁻]

⇒ (2x)²(x) = 8.00 × 10⁻⁵¹

⇒ 4x³ = 8.00 × 10⁻⁵¹

⇒ x³ = 2.00 × 10⁻⁵¹

⇒ x = ∛(2.00 × 10⁻⁵¹)

= 1.24 × 10⁻¹⁷ mol/L

The molar mass of Ag2S is

(2 × 107.9 g/mol) + 32.1 g/mol = 243.9 g/mol.

Therefore, the solubility of Ag2S in grams per liter is:

S = (1.24 × 10⁻¹⁷ mol/L) × (243.9 g/mol)

= 3.02 × 10⁻¹⁶ g/L

Hence, the solubility of Ag2S in grams per liter is 3.02 × 10⁻¹⁶.
