Due to an absence of hydrogen bonding, an ester's water solubility is greater for smaller esters. Here option D is the correct answer.

The water solubility of an ester, a type of organic compound with the functional group RCOOR', depends on several factors, including the size and polarity of the ester molecule. Generally, smaller esters are more soluble in water than larger esters due to their lower molecular weight and the presence of polar functional groups.

Although esters can participate in hydrogen bonding with water molecules, this interaction is not strong enough to overcome the hydrophobic effect, which causes nonpolar molecules to aggregate in water.

In addition, the size of the ester molecule can also hinder hydrogen bonding interactions with water. Option B, "lower for smaller esters due to hydrogen bonding," is also incorrect for the reasons mentioned above.

Option C, "nonexistent due to hydrogen bonding," is also incorrect. Esters can dissolve in water to some extent due to their polar carbonyl group, which can interact with water molecules through hydrogen bonding.

The volume of carbon dioxide produced is approximately (d) 11.9 liters.

To determine the amount of carbon dioxide (C\(O_2\)) produced when 37.8 grams of carbon disulfide (C\(S_2\)) reacts with excess oxygen gas (\(O_2\)), we need to use stoichiometry and the given balanced chemical equation:

C\(S_2\)(l) + 3\(O_2\)(g) → C\(O_2\)(g) + 2S\(O_2\)(g)

First, we calculate the number of moles of C\(S_2\) using its molar mass:

Molar mass of (C\(S_2\)) = 12.01 g/mol (C) + 32.07 g/mol (S) × 2 = 76.14 g/mol

Number of moles of (C\(S_2\)) = mass / molar mass = 37.8 g / 76.14 g/mol ≈ 0.496 mol

From the balanced equation, we can see that the stoichiometric ratio between (C\(S_2\)) and C\(O_2\) is 1:1. Therefore, the number of moles of C\(O_2\) produced will also be 0.496 mol.

Now we can use the ideal gas law to calculate the volume of C\(O_2\) at the given temperature and pressure. The ideal gas law equation is:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin.

Converting the temperature from Celsius to Kelvin:

T(K) = 28.85°C + 273.15 = 302 K

Using the ideal gas law:

V = nRT / P = (0.496 mol) × (0.0821 L·atm/mol·K) × (302 K) / (1.02 atm) ≈ 11.9 L

The correct answer is 11.9 liters.

Answer:

No mass of HCl could be left over by the chemical reaction because is the limting reactant and it is all consumed.

Explanation:

Our reactants are: HCl and NaOH

Products are: NaCl and H₂O

This is a neutralization reaction that can also be called an acid base reaction, an acid and a base react to produce water and a neutral salt, in this case where we have strong acid and base.

Ratio is 1:1. We convert mass to moles:

35 g . 1 mol / 36.45 g = 0.960 moles of HCl

73 g . 1 mol / 40 g = 1.82 moles of NaOH

As ratio is 1:1, for 0.960 moles of HCl we need 0.960 moles of NaOH and for 1.82 moles of NaOH, we need 1.82 moles of acid.

As we only have 0.960 moles of HCl and we need 1.82 moles, no acid remains after the reaction goes complete. HCl is the limiting reactant, so the acid, it is all consumed.

The blood alcohol level in mass percent is 0.0956% if 8.33 mL of 0.04988 M \(K2Cr2O7\) is required for titration of a 9.9950 g sample of blood.

To calculate the blood alcohol level in mass percent, we need to first determine the amount of ethanol present in the blood sample. This can be done by using a redox titration with potassium dichromate \((K2Cr2O7)\), which oxidizes the ethanol to acetic acid.

The balanced chemical equation for the reaction is:

\(C2H5OH + 2Cr2O7^2- + 16H+ → 2CO2 + 4Cr^3+ + 11H2O\)

From the balanced equation, we can see that the stoichiometric ratio between \(K2Cr2O7\) and ethanol is 2:1. Therefore, the moles of ethanol in the blood sample can be calculated as:

moles of ethanol = 0.5 × moles of \(K2Cr2O7\)

The moles of \(K2Cr2O7\)can be determined from its concentration and volume used in the titration:

\(moles of K2Cr2O7 = 0.04988 mol/L × 8.33 × 10^-3 L = 4.15 × 10^-4 mol\)

Substituting this value into the equation above, we get:

moles of ethanol = 0.5 × 4.15 × 10^-4 mol = 2.075 × 10^-4 mol

The mass of ethanol in the blood sample can be calculated from its molar mass:

\(mass of ethanol = 2.075 × 10^-4 mol × 46.07 g/mol = 9.551 × 10^-3 g\)

Finally, the blood alcohol level in mass percent can be titration calculated as:

mass percent = mass of ethanol / mass of blood sample × 100%

mass percent = \(9.551 × 10^-3 g / 9.9950 g × 100%\)

mass percent = 0.0956%

Therefore, the blood alcohol level in mass percent is 0.0956%.

The [H3O+] of a solution with pH = 8.7 is approximately 1.995 x 10^-9 M.

What is ph solution ?

The pH of a solution is a measure of its acidity or basicity. It is defined as the negative logarithm (base 10) of the concentration of hydronium ions, [H3O+], in the solution. Mathematically, pH is expressed as:

pH = -log[H3O+]

where [H3O+] is the concentration of hydronium ions in moles per liter (M) of the solution. pH values range from 0 to 14, where a pH of 7 is considered neutral. A pH value less than 7 indicates acidity, while a pH value greater than 7 indicates basicity or alkalinity. The pH scale is logarithmic, meaning that a change of one unit in pH represents a ten-fold change in the concentration of hydronium ions. For example, a solution with a pH of 3 has ten times more hydronium ions than a solution with a pH of 4.

The pH of a solution is defined as the negative logarithm (base 10) of the concentration of hydronium ions, [H3O+], in the solution. The mathematical expression for this relationship is:

pH = -log[H3O+]

We can rearrange this equation to solve for [H3O+]:

[H3O+] = 10^(-pH)

Substituting the given pH value of 8.7 into this equation, we get:

[H3O+] = 10^(-8.7)

Using a calculator or logarithmic tables, we find that:

[H3O+] = 1.995 x 10^(-9) M

Therefore, The [H3O+] of a solution with pH = 8.7 is approximately 1.995 x 10^-9 M.

The pressure exerted by a column of mercury that is about 760 mm high corresponds to approximately 0.987 atm.

To calculate the pressure exerted by a column of mercury, we can use the formula:

Pressure = density * gravity * height

Given:

Density of mercury = 13.6 g/cm³

Height of the mercury column = 760 mm = 76 cm

Acceleration due to gravity = 9.8 m/s²

First, we need to convert the height of the mercury column from centimeters to meters:

Height = 76 cm * (1 m / 100 cm) = 0.76 m

Now, we can calculate the pressure:

Pressure = 13.6 g/cm³ * 9.8 m/s² * 0.76 m

To ensure consistent units, we need to convert the density from grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³):

Density = 13.6 g/cm³ * (1 kg / 1000 g) * (1 cm³ / (1e-6 m³))

Density = 13600 kg/m³

Plugging in the values into the pressure formula:

Pressure = 13600 kg/m³ * 9.8 m/s² * 0.76 m

Pressure = 99992.8 Pa

We can express the pressure in terms of atmospheric pressure:

1 atm = 101325 Pa (approximately)

To compare the pressure with atmospheric pressure, we can convert 99992.8 Pa to atm:

Pressure in atm = 99992.8 Pa / 101325 Pa/atm

Pressure in atm ≈ 0.987 atm

The pressure exerted by a column of mercury that is about 760 mm high corresponds to approximately 0.987 atm. Since atmospheric pressure near sea level is approximately 1 atm, this calculation supports the claim that atmospheric pressure near sea level is equivalent to the pressure exerted by a column of mercury about 760 mm high.

Explanation:

Therefore, the volume of 1.20 M FeCl₂ required to obtain 0.850 moles of Cl⁻ ions is 0.354 L.

What is Moles?

One mole of a substance is defined as the amount of that substance that contains the same number of entities, such as atoms, molecules, or ions, as there are in 12 grams of carbon-12. This number, known as Avogadro's number, is approximately 6.022 x 10²³.

The molecular formula for FeCl₂ shows that it contains 2 chloride ions (Cl⁻) for each FeCl₂ molecule. Therefore, the number of moles of Cl⁻ ions is twice the number of moles of FeCl₂.

Given that we want to obtain 0.850 moles of Cl⁻ ions, we can calculate the number of moles of FeCl₂ required as follows:

moles of FeCl₂ = 0.850 moles Cl⁻ ions / 2 = 0.425 moles FeCl₂

To calculate the volume of 1.20 M FeCl₂ required to obtain 0.425 moles, we can use the formula:

moles = concentration (in M) x volume (in L)

Rearranging this formula to solve for volume, we get:

volume (in L) = moles / concentration (in M)

Substituting the values we have, we get:

volume (in L) = 0.425 moles / 1.20 M = 0.354 L

Therefore, the volume of 1.20 M FeCl₂ required to obtain 0.850 moles of Cl⁻ ions is 0.354 L.
