Sorbitol is one of the main photosynthetic end products and serves as a storage and transport sugar in most plant families. Synthesis of sorbitol takes place by catalysis of glucose via NADP-dependent sorbitol-6-phosphate dehydrogenase (S6PDH). Sorbitol is further degraded to fructose by NAD+ sorbitol dehydrogenase in sink tissues. It plays an important role in osmotic adjustment in cell cytoplasm under various abiotic stresses such as salinity, chilling, and drought .Sorbitol is slowly absorbed by passive diffusion in the small intestine.Sorbitol is a white, hygroscopic, crystalline powder. It melts at 97°C and has excellent pH and heat stability in food processing.

Explanation:

To determine the molar mass of the gas, we need to use the ideal gas law equation:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature. We can rearrange this equation to solve for the number of moles:

n = (PV) / (RT)

We are given the mass of the gas (0.643 g), the volume (125 mL), the pressure (60. cm Hg), and the temperature (25°C). To use these values in the ideal gas law equation, we need to convert the volume to liters and the pressure to atmospheres (atm) and the temperature to Kelvin (K):

V = 125 mL = 0.125 L

P = 60. cm Hg = 0.789 atm (using the conversion factor 1 atm = 760 mm Hg and 1 cm Hg = 1.33322 mm Hg)

T = 25°C + 273.15 = 298.15 K

Substituting these values into the ideal gas law equation and solving for n gives:

n = (PV) / (RT) = (0.789 atm x 0.125 L) / (0.0821 L·atm/mol·K x 298.15 K) = 0.00314 mol

To find the molar mass, we can use the formula:

molar mass = mass of sample / number of moles

molar mass = 0.643 g / 0.00314 mol = 204.46 g/mol

Therefore, the molar mass of the gas is approximately 204.46 g/mol.

Answer:

To determine the molar mass of the gas, we need to use the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. We can rearrange this equation to solve for n:

n = PV/RT

First, we need to convert the pressure to atmospheres (atm) and the volume to liters (L):

cm Hg = 0.788 atm (using the conversion factor 1 atm = 760 mm Hg)

125 mL = 0.125 L

Next, we can substitute the given values into the equation and solve for n:

n = (0.788 atm)(0.125 L)/(0.0821 L·atm/mol·K)(298 K) = 0.00472 mol

Finally, we can calculate the molar mass by dividing the mass of the sample by the number of moles:

molar mass = 0.643 g/0.00472 mol = 136 g/mol (rounded to three significant figures)

Therefore, the molar mass of the gas is approximately 136 g/mol.

Answer:

\(-675.053\ \text{kJ/mol}\)

Explanation:

\(\Delta G\) = Gibbs free energy = \(-775.41\ \text{kJ/mol}\)

\(\Delta S\) = Change in entropy = \(817.91\ \text{J/mol K}=0.81791\ \text{kJ/mol K}\)

\(T\) = Temperature = \(135.4^{\circ}\text{C}=408.55\ \text{K}\)

\(\Delta H\) = Change in enthalpy

Gibbs free energy is given by

\(\Delta G=\Delta H-T\Delta S\\\Rightarrow \Delta H=\Delta G+T\Delta S\\\Rightarrow \Delta H=-775.41+408.55\times 0.81791\\\Rightarrow \Delta H=-441.253\ \text{kJ/mol}\)

\(T=12.7^{\circ}\text{C}=285.85\ \text{K}\)

\(\Delta G=\Delta H-T\Delta S\\\Rightarrow \Delta G=-441.253-285.85\times 0.81791\\\Rightarrow \Delta G=-675.053\ \text{kJ/mol}\)

The required Gibbs free energy is \(-675.053\ \text{kJ/mol}\).

The word "symptom" refers to a specific manifestation or indication of a condition, disease, or disorder that is experienced or observed by an individual.

Symptoms are subjective or objective changes in the body's normal functioning that may be recognized as abnormal, uncomfortable, or problematic. Symptoms can manifest in various ways depending on the nature of the underlying condition. They can be physical, such as pain, rash, cough, fever, or fatigue, indicating an illness or injury affecting the body. Symptoms can also be psychological, such as anxiety, depression, or confusion, reflecting disturbances in mental health.

Symptoms serve as important clues for medical professionals to identify and diagnose diseases or disorders. They provide valuable information about the nature, severity, and progression of an illness, helping healthcare providers formulate appropriate treatment plans. Additionally, symptoms may also be important for individuals to self-assess their own health status and seek appropriate medical attention.

It is essential to note that symptoms alone may not provide a definitive diagnosis, as they can overlap across different conditions. Further evaluation, including medical tests and examinations, is often necessary to confirm a diagnosis and determine the appropriate course of action.

The volume of hydrogen gas produced in the reaction of 73 grams of zinc and 73 grams of hydrochloric acid (under normal conditions) is approximately 22.4 liters.

To calculate the volume of hydrogen gas produced in the reaction of zinc and hydrochloric acid, we need to use the principles of stoichiometry and the ideal gas law.

First, let's write the balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl):

Zn + 2HCl →\(ZnCl_2\)+ H2

From the equation, we can see that one mole of zinc reacts with two moles of hydrochloric acid to produce one mole of hydrogen gas. To determine the number of moles of zinc and hydrochloric acid, we need to convert the given masses into moles.

The molar mass of zinc (Zn) is approximately 65.38 g/mol, so 73 grams of zinc is equal to:

73 g Zn * (1 mol Zn / 65.38 g Zn) ≈ 1.116 mol Zn

Similarly, the molar mass of hydrochloric acid (HCl) is approximately 36.46 g/mol, so 73 grams of HCl is equal to:

73 g HCl * (1 mol HCl / 36.46 g HCl) ≈ 2.002 mol HCl

According to the balanced equation, the reaction produces one mole of hydrogen gas for every two moles of hydrochloric acid. Therefore, since we have 2.002 moles of HCl, we expect to produce half that amount, or approximately 1.001 moles of hydrogen gas.

To calculate the volume of hydrogen gas, we can use the ideal gas law, which states:

PV = nRT

Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. In this case, we assume the reaction is conducted under normal conditions, which means a pressure of 1 atmosphere and a temperature of 273.15 Kelvin.

Rearranging the equation to solve for V, we have:

V = nRT / P

Substituting the values, we get:

V = (1.001 mol) * (0.0821 L·atm/(mol·K)) * (273.15 K) / (1 atm) ≈ 22.4 L

Therefore, the volume of hydrogen gas produced in the reaction is approximately 22.4 liters.

Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution. Thus the molarity of \(KNO_{3}\),\(BaCl_{2}\),\(Na_{2}CO_{3}\) and\(C_{6}H_{12}O_{6}\) are 5.2mol/litre, 5mol/litre, 0.97mol/litre, 28mol/litre respectively.

Molarity can be calculated by dividing  number of moles of solute by volume of solution in liter.

Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution

Mathematically,

Molarity= number of moles of solute/volume of solution in litre (1)

1) Molarity of \(KNO_{3}\)= {1.30 mol ×(1000ml/l)}÷250.0 mL=5.2mol/litre

2)Molarity of \(BaCl_{2}\)= {0.500 mol  ×(1000ml/l)}÷100.0 mL=5mol/litre

3)Molarity of\(Na_{2}CO_{3}\)= {0.195 mol   ×(1000ml/l)}÷200.0 mL=0.97mol/litre

4)Molarity of \(C_{6}H_{12}O_{6}\) = {7.00 mol  ×(1000ml/l)}÷ 250.0 mL=28mol/litre

Thus the molarity of \(KNO_{3}\),\(BaCl_{2}\),\(Na_{2}CO_{3}\) and\(C_{6}H_{12}O_{6}\) are 5.2mol/liter, 5mol/litre, 0.97mol/litre, 28mol/litre respectively.
