The property associated with the existence of glycine as a dipolar ion in aqueous solution is High dipole moment

What is dipole moment?

Dipole moments occur when there is a separation of charge. Dipole moments can exist between two ions in an ionic bond or between atoms in a covalent link; they are caused by changes in electronegativity. The dipole moment grows in proportion to the difference in electronegativity.

According to the question,

Glycine exists as a "dipolar ion in aqueous solution." Polarity in neutral molecules is caused by an unequal distribution of electron density, which might result from the separation of opposite charges. This happens in zwitterions.  Also, molecules that have strong electron-withdrawing or electron-donating substituents are highly polar and have high dipole moments.

1)Grignard reagent when reacted with methanol will yield A) ethanol (B) secondary alcohols (C) tertiary alcohols (D ropanol (E) primary alcohol

Answers

When the reaction of  Grignard reagent reacted with methanol will yield a tertiary alcohol. Therefore, Option C tertiary alcohol is correct.

Contains a carbon-metal link, Grignard reagents are chemicals used in catalysis. They generally result from the anhydrous reaction of magnesium metal with an alkyl or aryl halide. Because of their high reactivity, Grignard reagents frequently act as nucleophiles in organic reactions.

An alkyl group from a Grignard reagent binds to the oxygen atom of methanol (CH3OH) when it interacts with the methanol, breaking the carbon-metal connection. A precursor alkoxide is created as a result. The equivalent alcohol is then produced by protonating the intermediate alkoxide.

The reaction of a Grignard reagent with methanol leads to the formation of a tertiary alcohol.

what are the limiting and excess reactants when 3.22 moles of Al react with 6.96 moles of HBr

what are the limiting and excess reactants when 3.22 moles of Al react with 6.96 moles of HBr

Answers

Answer

HBr is the limiting reactant

Al is the excess reactant.

Explanation

Given:

Moles of Al = 3.22 mol

Moles of HBr = 6.96 mol

Equation: 2 Al + 6 HBr → 2 AlBr₃ + 3 H₂

What to find;

The limiting and excess reactants.

Solution:

Note: The limiting reactant is the reactant that is completely used up in a reaction, and thus determines when the reaction stops. While the excess reactant is the opposite.

From the given balanced chemical equation;

2 moles of Al require 6 moles of HBr

Therefore, the given 3.22 moles of Al will require (3.22/2) x 6 = 9.66 moles of HBr

Since the given moles of HBr is 6.96 mol not up to 9.66 moles required, then HBr is the limiting reactant and Al is the excess reactant.

HBr is the limiting reactant

Al is the excess reactant.

loan over the next five years. How much interest did the student pay?

Answers

The student paid an interest of $3,000 over the next five years.

HOW TO CALCULATE INTEREST:

The interest on a borrowed amount of money can be calculated by subtracting the principal from the amount paid over time. That is;

Interest = principal - amount

According to this question, a student borrows $10,000 from a bank but ends up paying $13,000. This means that the principal is $10,000 while the amount is $13,000. The interest is calculated thus;

Interest = $13,000 - $10,000

Interest = $3,000

Answers

According to the given reaction, 1 mole of Mg3N2 reacts with 3 moles of H2O.

This, converted to mass, is 101g of Mg3N2 react with 54g of H2O.

From this we can conclude that the limit reagent is Mg3N2.

We have to base our calculation on the mass of Mg3N2 given.

During the reaction, 3 moles of MgO are produced from 101g of Mg3N2. This, converted to mass, is 120.9g of MgO.

NOTE: LET ME KNOW IF YOU WANT A PICTURE OF THE LAB INSTRUCTIONS TO HELP SOLVE

Answers

To determine the universal gas constant (R), we can use the ideal gas law equation: PV = nRT, where P is the total pressure, V is the volume of gas, n is the number of moles, R is the universal gas constant, and T is the temperature in Kelvin.

Barometric pressure of the room: To find the barometric pressure in atm, we convert 766.86 mmHg to atm by dividing it by 760 mmHg/atm, giving us 1.0089 atm.Vapor pressure of water at room temperature (PH2O).The vapor pressure of water at 23.0°C is 0.0313 atm.

Mass difference of butane lighter:The mass difference is calculated by subtracting the initial mass (54.24 g) from the final mass (54.01 g), resulting in a difference of 0.23 g.

Moles of butane gas collected:To find the moles of butane gas, we can use the equation n = m/M, where n is the number of moles, m is the mass, and M is the molar mass of butane (58.12 g/mol). Thus, n = 0.23 g / 58.12 g/mol = 0.003959 mol.

Partial pressure of butane gas:The partial pressure of butane gas is calculated by multiplying the moles of butane gas (0.003959 mol) by the ideal gas constant (R) and the converted temperature (23.0°C + 273.15 K). Let's assume the converted temperature is 296.15 K.

Converted volume of gas collected:The volume of gas collected is given as 100.0 mL, which needs to be converted to liters by dividing it by 1000, resulting in 0.1 L.

Experimental value of R:The experimental value of R can be determined by rearranging the ideal gas law equation to solve for R: R = (P - PH2O) * V / (n * T).

Accepted value of R:The accepted value of R is 0.0821 Latm/molK.

The percent error can be calculated using the formula: (|Experimental value - Accepted value| / Accepted value) * 100.

Factors contributing to percent error could include experimental error in mass measurements, inaccurate temperature measurements, and loss of gas during collection or transfer.

If the gas had not been corrected for the partial pressure of water, the value of R would be lower because the partial pressure of water would contribute to the total pressure, resulting in a smaller value for P in the ideal gas law equation.

To increase accuracy and decrease percent error, the experiment could be repeated multiple times to obtain an average value, use more precise measuring instruments, conduct the experiment in a controlled environment, and ensure accurate calibration of equipment.

what is the molar mass of a gas with a density of 1.34g / l at STP?

Answers

Considering the STP conditions and the definition of molar mass, the molar mass of the gasis equal to 30.016 g/mole.

STP conditions

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0°C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Definition of molar mass

Molar mass is the amount of mass that a substance contains in one mole.

Molar mass of a gas with a density of 1.34 g/L at STP

The density of a substance is the mass you have per unit of volume of that substance. So you know that 1.43 g/L means that 1 L of this gas has a mass of 1.43 g.

Knowing that one mole of gas at STP occupies 22.4 litres, you can say that 1 mole of this gas will have a mass of:

22.4 L× \(\frac{1.34 g}{1 L} \)= 30.016 g

Finally, if 1 mole of this gas has a mass of 30.016 g, its molar mass is equal to 30.016 g/mole.

Answers

Answer:

A. The reaction shifts to the right (products) and the concentrations of I and H₂ decrease.

Explanation:

If gas is removed from the system at equilibrium, the system will try to compensate for the loss by shifting the reaction in a direction that produces more gas molecules. This is known as Le Chatelier's principle, which states that a system at equilibrium will respond to a disturbance by shifting in a way that minimizes the effect of the disturbance.

In this case, since gas is being removed from the system, the reaction will shift to the side that produces more gas molecules. Looking at the balanced equation, we can see that 2HI(g) has a greater number of gas molecules compared to H₂(g) and I₂(g). Therefore, the system will shift to the right (products) to produce more HI(g) and reestablish equilibrium.

Employing the ideal gas model for the air, determine a. the final temperature of the air, in K. b. the final pressure of the air, in bar. c. the amount of entropy produced, in kJ/K.

Answers

The entropy indicates the amount of thermodynamic energy that is not

available for work.

a. The final temperature is 400 K

b. The final pressure is 2.25 bar

c. The amount entropy produced, Δs is approximately 0.063712 kJ/K

Reason:

The given parameters are;

Type of box = Insulated

Volumes into which the box is divided = Equal volumes

Type of piston = Frictionless, thermally conducting

Volume on each side of the piston = 1.0 m³

Temperature on each side of the piston, T₁ = T₂ = 400 K

Pressure on one side of the piston = 3.0 bar

Pressure on the other side of the piston = 1.5 bar

a. The final temperature of the air;

Given that the piston is frictionless and allowed move freely, and  air is

contained on both sides of the piston, we have;

The system is equivalent to the piston being removed such that the gas

moves freely in the box.

Therefore, the high pressured side drops in temperature while the low

pressure side gains temperature, such that the change in temperature is

zero.

Which gives; T₁ = T₂ = \(T_f\)

Therefore;

The final temperature, \(\mathbf{T_f}\) = T₁ = T₂ = 400 K

b. The final pressure is given as follows;

We have;

\(\dfrac{P_{1}\times V_{1}}{T_{1}} = \dfrac{P_{f}\times (V_{1} -V) }{T_{f}}\)

\(\dfrac{3\times 1}{400} = \dfrac{P_{f}\times (1+V) }{T_{f}}\)

\(\dfrac{P_{2}\times V_{2}}{T_{2}} = \dfrac{P_{f}\times (V_{2} +V) }{T_{f}}\)

\(\dfrac{1.5\times 1}{400} = \dfrac{P_{f}\times (1 -V) }{T_{f}}\)

\(\dfrac{1 + V}{1 - V} = 2\)

Which gives;

\(V = \dfrac{1}{3}\)

\(T_f\) = 400 K, gives;

\(\dfrac{1.5\times 1}{400} = \dfrac{P_{f}\times \left (1 -\dfrac{1}{3} \right) }{400} = \dfrac{\dfrac{2}{3} \cdot P_f}{400}\)

\(1.5\times 1} =\dfrac{2}{3} \cdot P_f}\)

\(P_f = \dfrac{3 \times 1.5\times 1 }{2} = 2.25\)

The final pressure, \(\mathbf{P_f}\) = 2.25 bar

c. The amount of entropy produced, in kJ/K

The change in entropy is given by the formula;

\(\Delta s = \Delta s_1 + \Delta s_1 = -R \cdot \dfrac{P_1 \cdot V_1}{R \cdot T_1} \cdot ln\dfrac{P_f}{P_1} + \left(-R \cdot \dfrac{P_2 \cdot V_2}{R \cdot T_2} \cdot ln\dfrac{P_f}{P_2} \right)\)

\(\Delta s = -\dfrac{P_1 \cdot \dfrac{V}{2} }{ T_f} \cdot ln\dfrac{P_f}{P_1} + \left(-\dfrac{P_2 \cdot \dfrac{V}{2} }{ T_f} \cdot ln\dfrac{P_f}{P_2} \right)\)

Which gives;

\(\Delta s = -\dfrac{3 \times \dfrac{2}{2} }{ 400} \cdot ln\dfrac{2.25}{3} + \left(-\dfrac{1.5 \cdot \dfrac{2}{2} }{ 400} \cdot ln\dfrac{2.25}{1.5} \right) \approx 6.371 \times 10^{-4}\)

Δs = 6.371 × 10⁻⁴ bar·m³/K = 63.712 J/K = 0.063712 J/K

The entropy produced, Δs = 0.063712 kJ/K.
