Answer:

(CH3COO)2 + redP + Cl2 → ClCH2COOH + HCl

Explanation:

This is an example of halogenation of carboxylic acids at alpha carbon atom. In this reaction, red phosphorus and chlorine are treated with carboxylic acids having alpha hydrogen atom followed by hydrolysis to form alpha chloro carboxylic acid.

i) No reactant will be left as all of them have been converted to product after completion of this reaction.

ii) Final percentage of each reactant remaining if each reaction went to completion is about 99.9%.

The difference between the moles (or molecules) of reactants consumed and the moles (or molecules) of products produced in a chemical reaction is known as the molar ratio.

i) Now given the molar ratio of CV : NaOH is 1:1 . That means Equal moles of CV and NaOH are present in the solution. That means all the CV and NaOH molecules will react to form equal number of products.

So in this case, no reactant will be left as all of them have been converted to product after completion of reaction.

ii) In this case, the given NaOH : CV = 1000 : 1. That means per 1000 moles of NaOH, we have only 1 mole of CV. Now since 1 mole of CV can react with only 1 mole of NaOH, then after the reaction of this 1 mole CV, there will be no CV left . And only 999 NaOH molecules will be left in the solution

So here % CV left = 0%

% of NaOH left = 999 / 1000 × 100

% of NaOH left = 99.9 %

The most stable contributor's structure is the genuine structure of the resonance hybrid. The delocalization of electrons is what stabilizes the resonance hybrid. The potential resonance forms are quickly interconverted by a resonance hybrid.

Equivalent resonance types equally contribute to the hybrid's overall structure. Consider the resonance hybrid structure of a carboxylate group as an example. Different resonance contributors do not always contribute equally to the hybrid structure until they are equivalent to one another in terms of stability, as is the case for the carboxylate group, which has equivalent contributions from A and B as shown in the given figure. One resonance structure will more closely resemble the “actual” (hybrid) structure than another if it is more stable (lower in energy) than the other.

According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

Answer: The thermodynamic favorability of a chemical reaction can be determined by comparing the change in free energy (ΔG) between the reactants and products. A negative value of ΔG indicates that the reaction is thermodynamically favored, meaning that it is energetically favorable for the reaction to proceed in the forward direction. Conversely, a positive value of ΔG indicates that the reaction is not thermodynamically favored, and the reverse reaction is energetically favorable.

If the ΔG of the forward reaction is negative, the forward reaction will be thermodynamically favored, and the reverse reaction will not be. If the ΔG of the forward reaction is positive, the reverse reaction will be thermodynamically favored, and the forward reaction will not be. If the ΔG of the forward reaction is zero, the reaction is at equilibrium and neither the forward nor the reverse reaction is thermodynamically favored.

Therefore, whether the forward or reverse reaction is thermodynamically favored depends on the magnitude and sign of ΔG for that reaction.

a. BeCl₂:

The Lewis dot structure for BeCl₂ is:

Be: Cl - Be - Cl

Electron domain geometry: Linear

Molecular geometry: Linear

BeCl₂ does not have polar bonds because beryllium (Be) and chlorine (Cl) have similar electronegativities, resulting in a symmetrical distribution of charge. Therefore, BeCl₂ is a nonpolar molecule.

b. XeF₂:

The Lewis dot structure for XeF₂ is:

F-Xe-F

Electron domain geometry: Linear

Molecular geometry: Linear

XeF₂ does not have polar bonds because xenon (Xe) and fluorine (F) have similar electronegativities, resulting in a symmetrical distribution of charge. Therefore, XeF₂ is a nonpolar molecule.

c. SCl₂:

The Lewis dot structure for SCl₂ is:

Cl-S-Cl

Electron domain geometry: Trigonal planar

Molecular geometry: Bent or V-shaped

SCl₂ has polar bonds because sulfur (S) is less electronegative than chlorine (Cl), resulting in a partial positive charge on sulfur and partial negative charges on the chlorine atoms. The bond dipole moments point towards the chlorine atoms. Therefore, SCl₂ is a polar molecule.

The amount of heat in joules required to increase the temperature of a 49.5-gram sample of water from 22 degrees Celsius to 66 degrees Celsius is 104,751 Joules.

The formula for calculating the amount of heat required to raise the temperature of an object is given as Q = mcΔT where Q is the heat energy in Joules, m is the mass in kilograms, c is the specific heat capacity in Joules per kilogram Celsius, and ΔT is the change in temperature in Celsius. The specific heat capacity of water is 4.18 Joules per gram Celsius.

Therefore, the amount of heat required to raise the temperature of the 49.5-gram sample of water is calculated as: Q = mcΔTQ = (49.5 g) x (4.18 J/g°C) x (66°C - 22°C)Q = 104,751 Joules The amount of heat in joules required to increase the temperature of a 49.5-gram sample of water from 22 degrees Celsius to 66 degrees Celsius is 104,751 Joules. In order to find out the amount of heat required to increase the temperature of a substance, we use the formula Q = mcΔT. Q is the heat energy in Joules, m is the mass in kilograms, c is the specific heat capacity in Joules per kilogram Celsius, and ΔT is the change in temperature in Celsius. The specific heat capacity of water is 4.18 Joules per gram Celsius. Therefore, we can calculate the amount of heat required to raise the temperature of the 49.5-gram sample of water as: Q = mcΔTQ = (49.5 g) x (4.18 J/g°C) x (66°C - 22°C)Q = 104,751 Joules This means that if we want to increase the temperature of a 49.5-gram sample of water from 22 degrees Celsius to 66 degrees Celsius, we would need to add 104,751 Joules of heat to the system. It is important to note that different substances have different specific heat capacities, which means that the amount of heat required to raise their temperature would be different. Water has a relatively high specific heat capacity, which means that it requires more heat energy to increase its temperature than other substances.
