There are three different dichloroethylenes (molecular formula C₂H₂Cl₂), which we can designate X, Y, and Z. Compound X has no dipole moment, but compound Z does. Compounds X and Z each combine with hydrogen to give the same product:
C₂H₂Cl₂(X or Z) + H₂ → ClCH₂ - CH₂Cl
What are the structures of X, Y, and Z? Would you expect compound Y to have a dipole moment?
Answers
Compound X= (E)-1,2-dichloroethene
Compound Y= 1,1-dichloroethene
Compound Z= (Z)-1,2-dichloroethene
Elaboration :
In this case we will have 3 isomers which have the same formula. If we use the formula, the options we have are that the chlorides are attached to the same carbon (compound Y) or different carbons (Compounds X and Y).
Now, the problem gives a clue about compounds X and Y, hydrogenation results in the same compound (see figure) therefore the only difference between the compounds is the orientation of the Cl groups, therefore one of them it must be "E" and the other "Z" (this nomenclature should be used for alkenes, since the cis / trans nomenclature is used for other types of molecules),
so the question is which is the cis isomer and which is the Isomer Z ?
The problem says that compound X has no dipole moment, therefore in compound X the Cl groups must have opposite directions such that the dipole moments of both cancel each other out. In conclusion, compound X is the isomer E, compound Y is the compound in which the Cl groups are on the same carbon and compound z is the isomer Z.
So, yes Y will have a dipole moment
Dipole moment :
A dipole moment is a measurement of the separation of two opposite electrical charges. Dipole moments are a vector quantity. The magnitude is equal to the charge multiplied by the distance between the charges and the direction is from negative charge to positive charge: μ = q · r.

S2O3 2- + OH- → SO4 2- + H2O + e-. After the above half-reaction is balanced, which of the following are the respective coefficients of OHand SO4 2-? (A) 8 and 3 (B) 6 and 2 (C) 10 and 2 (D) 5 and 2 (E) 5 and 1
Answers
The balanced half-reaction is \(S_2O_3 ^2- + 3OH^- -- > SO_4^ {2-} + H_2O + e^-\). The respective coefficients of OH- and \(SO_4^ 2-\) are 3 and 1, so the correct answer is (E) 5 and 1.
To balance the given half-reaction, \(S_2O_3^2- + OH^- -- > SO_4^ 2- + H_2O + e^-\), we need to make sure that the number of atoms and charges are equal on both sides. Let’s examine the reaction and determine the coefficients of OH- and \(SO_4^ 2-\).
On the reactant side, we have \(S_2O_3 ^2-\) and OH-. The \(S_2O_3 ^2-\)- ion has a total charge of 2-. To balance the charge, we need 2 OH- ions with a charge of 1- each. So far, the equation looks like this:
\(S_2O_3^2- + OH^- -- > SO_4^ 2- + H_2O + e^-\)
Next, let’s balance the atoms. We have 3 oxygen atoms on the reactant side and 4 oxygen atoms on the product side . To balance the oxygen, we need to add 1 more OH- ion:
\(S_2O_3 ^2- + 3OH^- -- > SO_4^ {2-} + H_2O + e^-\)
Now, the equation is balanced with respect to charge and oxygen. The respective coefficients of OH- and \(SO_4^ 2-\) are 3 and 1, so the correct answer is € 5 and 1.
Therefore, the balanced half-reaction is \(S_2O_3 ^2- + 3OH^- -- > SO_4^ {2-} + H_2O + e^-\)

Answers
When burning 180 g of glucose in the presence of 192 g of oxygen, 108 g of water and 264 g of carbon dioxide are produced.
Let's consider the following balanced equation for the combustion of glucose.
C₆H₁₂O₆ + 6 O₂ ⇒ 6 CO₂ + 6 H₂O
According to Lavoisier's law of conservation of mass, matter is neither created nor destroyed in chemical reactions. Thus, the sum of the masses of the reactants before the reaction must be equal to the sum of the masses of the products after the reaction.

An old refrigerator is rated at 500 W how many kilowatt hours of electric energy what does refrigerator use in 30 days assume the refrigerator is running 12 hours per day
Answers
The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.
To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.
Given:
Power rating of the refrigerator = 500 W
Running time per day = 12 hours
Number of days = 30
First, we need to convert the power rating from watts to kilowatts:
Power rating = 500 W / 1000 = 0.5 kW
Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:
Energy used = Power rating × Running time × Number of days
Energy used = 0.5 kW × 12 hours/day × 30 days
Energy used = 180 kWh
Therefore, the refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

Deionized water is added to the flask such that the bottom of the meniscus is at the line. A 1.00 mL aliquot of the stock solution is transferred to a 50.00 mL volumetric flask using a volumetric pipet and diluted to volume. 6. Calculate the concentration of NaCl in the resulting solution in mg/L NaCl. (answer = 67.4 mg/L) 7. Calculate the concentration of NaCl in the resulting solution using propagation of error through the calculation. Use the manufacturer's tolerance values as the absolute error. The tolerances can be found in Chapter 2 of the Harris text. Assume a Class 1 balance and Class A glassware. Treat the tolerances as random error. (answer = 67.4+0.4 mg/L) 8. Identify 2 possible sources of random (indeterminate) error. Identify 2 possible sourses of systematic (determinate) error.
Answers
Two possible sources of systematic (determinate) error in the experiment are; Incorrect calibration of volumetric glasswareIncorrect mass of NaCl
To calculate the concentration of NaCl in the resulting solution in mg/L NaCl, we can use the formula; Concentration (mg/L) = (Mass of solute ÷ Volume of solution in L) × 1000 g / 1 mg NaCl is present in the stock solution of 25 mL. So, the mass of NaCl in the solution would be;0.0842 g ÷ 25 mL = 0.00337 g/mL. Now, in the resulting solution, a 1.00 mL aliquot of the stock solution is transferred to a 50.00 mL volumetric flask and diluted to volume. Therefore, the volume of the resulting solution is 50.00 mL. We will substitute these values in the formula, Concentration (mg/L) = (0.00337 g/mL ÷ 50 mL) × 1000 g / 1 mg concentration (mg/L) = 67.4 mg/L. Therefore, the concentration of NaCl in the resulting solution in mg/L NaCl is 67.4 mg/L.7. Concentration = 67.4 mg/LTolerance = 4.28 mg/LTotal concentration = 67.4 + 4.28 mg/L = 71.68 mg/LWe round off this value to one decimal place; Total concentration = 71.7 mg/LTherefore, the concentration of NaCl in the resulting solution using propagation of error through the calculation is 67.4+0.4 mg/L.8. Two possible sources of random (indeterminate) error in the experiment are; Errors in temperature measurement. Errors in measurement of water volume. Two possible sources of systematic (determinate) error in the experiment are; Incorrect calibration of volumetric glasswareIncorrect mass of NaCl.

What is the solubility of silver iodide in grams per milliliter at a temperature at which the Kₛₚ of Agl is 1.47 x 10 ⁻¹⁶?
Answers
The solubility product constant expression for AgI is:
AgI(s) ⇌ Ag⁺(aq) + I⁻(aq)
The Ksp expression for AgI is given as 1.47 x 10⁻¹⁶.
Since AgI dissociates into 1 Ag⁺ ion and 1 I⁻ ion, the molar solubility (s) of AgI is equal to the concentration of Ag⁺ and I⁻ ions in the solution.
Let's assume the molar solubility of AgI is s M.
Since the molar solubility (s) of AgI is equal to the concentration of Ag⁺ and I⁻ ions, we have:
[Ag⁺] = s M
[I⁻] = s M
Using the stoichiometry of the balanced equation, the expression for the solubility product constant is:
Ksp = [Ag⁺][I⁻] = s^2
Substituting the given Ksp value, we have:
1.47 x 10⁻¹⁶ = (s)^2
Taking the square root of both sides, we get:
s = √(1.47 x 10⁻¹⁶)
Calculating the square root, we find:
s ≈ 3.83 x 10⁻⁹ M
Since the solubility is given in grams per milliliter (g/mL), we need to convert the molar solubility to grams per milliliter using the molar mass of AgI.
The molar mass of AgI is:
Ag: 107.87 g/mol
I: 126.90 g/mol
AgI: 107.87 g/mol + 126.90 g/mol = 234.77 g/mol
To convert the molar solubility (s) to grams per milliliter (g/mL):
s (g/mL) = (molar solubility (M) * molar mass of AgI (g/mol)) / 1000
Substituting the values, we have:
s (g/mL) = (3.83 x 10⁻⁹ M * 234.77 g/mol) / 1000
Calculating the value, we find:
s (g/mL) ≈ 9.0 x 10⁻¹² g/mL
Therefore, the solubility of silver iodide (AgI) in grams per milliliter (g/mL) at the given temperature is approximately 9.0 x 10⁻¹² g/mL.
The solubility of silver iodide (AgI) in grams per milliliter can be calculated using the concept of solubility product constant (Kₛₚ). Given that the Kₛₚ of AgI is 1.47 x 10⁻¹⁶.
The solubility product constant (Kₛₚ) is a measure of the equilibrium between a solid and its dissolved ions in a saturated solution. For silver iodide (AgI), the equilibrium equation can be expressed as:
AgI(s) ⇌ Ag⁺(aq) + I⁻(aq)
The Kₛₚ expression for this equilibrium is:
Kₛₚ = [Ag⁺][I⁻]
Given the Kₛₚ value of AgI as 1.47 x 10⁻¹⁶, it indicates that the product of the concentrations of Ag⁺ and I⁻ ions in the saturated solution is equal to 1.47 x 10⁻¹⁶.
To determine the solubility of AgI in grams per milliliter, we need to know the molar mass of AgI and the volume of the saturated solution. The molar mass of AgI is 234.77 g/mol, which is the sum of the atomic masses of silver (Ag) and iodine (I).
To convert the concentration of Ag⁺ or I⁻ ions to grams per milliliter, we need to divide the concentration (in moles per liter) by the molar mass (in grams per mole) and multiply by the solution volume (in milliliters).
However, without the given volume of the saturated solution, it is not possible to calculate the solubility in grams per milliliter directly using the Kₛₚ value. The solubility information typically depends on both temperature and the presence of other ions or substances in the solution. Therefore, additional data or an experimental approach would be needed to determine the solubility of AgI in grams per milliliter at the given temperature.

Fincl the total capacitance of 0.0050 F connected in series?
Answers
The total capacitance of 0.0050 F connected in series is 5.0 × 10⁻⁶ F or 5.0 µF.
When capacitors are connected in series, their total capacitance is less than the smallest capacitance value. This is due to the fact that the effective distance between the capacitor plates increases as more capacitors are added. As a result, the total capacitance of 0.0050 F connected in series can be determined using the following formula:
1/Ceq = 1/C1 + 1/C2 + 1/C3 + ...
where C1, C2, C3, etc. are the capacitance values of the capacitors connected in series.
To compute the total capacitance, substitute the known values to the formula:
1/Ceq = 1/5.0 × 10⁻³ F
Here's how to solve for Ceq:

(c) The volume of a spherical vesicle is V = 3.34 × 10⁻¹⁷ L.
(d) The concentration of epinephrine = 0.30 M.
What is molar concentration.
A chemical species' concentration, specifically the amount of a solute per unit volume of solution, is measured by its molar concentration. The number of moles per litre, denoted by the unit sign mol/L or mol/dm3 in SI units, is the most often used molarity unit in chemistry.
(a) Evaluate that how many attomoles (amol) of epinephrine are in each vesicle?
As given,
1 fmol = 10⁻¹⁵ mol
1 amol = 10⁻¹⁸ mol
Number of attomoles epinephrine:
= 151 fmol × (10⁻¹⁵ mol)/ 1 fmol × 1amol/10⁻¹⁸ mol
= 151000 amol
Number of attomoles of epinephrine in each vescile:
= 151000 amol/2.5 × 10⁴ vescile
= 6.04 amol/vescile.
(b) Evaluate that how many molecules of epinephrine are in each vesicle?
Number of molecules present in 1 mol of epinephrine:
= 6.04/vescile × [(10⁻¹⁵ mol)/ 1 fmol] × [6.023 × 10²³ molecules/1 mol]
= 3637892
(c) Evaluate the volume of a spherical vesicle of radius 200 nm.
Radius of spherical vescile is 2.00 × 10⁻⁷ m
Volume of the spherical vescile is,
V = 4/3 πr³
Substitute value of r respectively,
V = 4/3 π(2.00 × 10⁻⁷ )³
V = 3.34 × 10⁻²⁰ m³
V = 3.34 × 10⁻¹⁷ L
(d) Evaluate the molar concentration of epinephrine in the vesicle if it contains 10 amol of epinephrine.
Number of moles epinephrine = 10 amol
= 1.00 × 10⁻¹⁷mol
Volume of the spherical vescile = 3.34 × 10⁻¹⁷ L
Concentration of epinephrine = (1.00 × 10⁻¹⁷mol)/(3.34 × 10⁻¹⁷ L)
Concentration of epinephrine = 0.30 M

The net ionic equation for the behavior of benzoic acid (C₆H₅COOH) as a Bronsted-Lowry acid in water is:
C₆H₅COOH + H₂O → C₆H₅COO⁻ + H₃O⁺
In water, ethylamine (C₂H₅NH₂) can act as a Bronsted-Lowry base by accepting a proton (H⁺) from water. The reaction can be represented by the net ionic equation: C₂H₅NH₂ + H₂O → C₂H₅NH₃⁺ + OH⁻. In this equation, ethylamine (C₂H₅NH₂) accepts a proton from water (H₂O) to form the ethylammonium ion (C₂H₅NH₃⁺) and hydroxide ion (OH⁻). This shows the base behavior of ethylamine as it accepts a proton.
On the other hand, benzoic acid (C₆H₅COOH) can act as a Bronsted-Lowry acid in water by donating a proton (H⁺) to water. The reaction can be represented by the net ionic equation: C₆H₅COOH + H₂O → C₆H₅COO⁻ + H₃O⁺.
In this equation, benzoic acid (C₆H₅COOH) donates a proton to water (H₂O) to form the benzoate ion (C₆H₅COO⁻) and hydronium ion (H₃O⁺). This demonstrates the acid behavior of benzoic acid as it donates a proton.
