Which one of the two phase transitions (freezing or vaporizing) has the larger magnitude in the change of entropy? Explain in terms of statistical model of entropy.

Answers

Answer 1

Entropy changes more significantly during phase transitions during freezing.

Change in entropy during a phase change is defined as:-

∆S = change in enthalpy/ temperature (absolute)

Enthalpy values in both processes are comparable.

But, since the temperature in freezing will be much lower than the temperature in vaporizing, enthalpy change in freezing will contribute to a larger magnitude of change in the randomness of the molecules. Hence, it's the magnitude of entropy change will be larger.

A state of disorder, randomness, or uncertainty is most frequently connected with the scientific notion of entropy, which is also a quantifiable physical attribute. The notion and the phrase are employed in a variety of disciplines, including classical thermodynamics, where they were initially identified, statistical physics, which describes nature at the molecular level, and information theory. It has wide-ranging uses in physics and chemistry, biological systems, and how they relate to life, cosmology, economics, sociology, weather science, and information systems, particularly the transfer of information through telecommunication.

in the electrolysis of water, how long will it take to produce 235.0 l of h2 at 1.0 atm and 273 k using an electrolytic cell through which the current is 221.0 ma? 1st attempt see hint hours

Answers

In the electrolysis of water, will it take to produce 235.0 l of H₂ at 1.0 atm and 273 k using an electrolytic cell through which the current is 221.0 mA is 25448 hour.

The ideal gas equation is given as :  

P V = n RT

pressure , P = 1 atm

volume , V = 235.0 L

temperature , T = 273 K

gas constant, R = 0.082 atm L /mol K

n = P V / R T

n = (1 × 235 ) / ( 273 × 0.082)

n = 10.49 mol

the reaction is given as :

2H⁺  +   2e⁻  ---->  H₂

number of electrons = 2

1 mole of electron = 96500 C

10.49 of electron = 10.49 × 2 × 96500

                         =  2024570 C

I = 221 mA = 0.221 C/s

q = It

t = q / I

t = 2024570 / 0.221

t = 9160950 s

t = 25448 hour

Thus, in the electrolysis of water, the tike taken is 25448 hour.

Molar mass of CuO = 63.5 + 16 = 79.5 g/molMass of CuO from the balanced equation = 2 × 79.5 = 159 g Molar mass of CuSO₄ = 63.5 + 32 + (16 × 4) = 159.5 g/molMass of CuSO₄ from the balanced equation = 2 × 159.5 = 319 g

Answers

To find the molarity of sodium in the soup, we need to first convert the mass of sodium in the soup to moles. The atomic weight of sodium is 22.99 g/mol, so we can use the following conversion to find the number of moles of sodium in the soup:

moles Na = (890 mg Na) / (22.99 g/mol) = 38.8 moles Na

Next, we need to find the volume of the soup in liters. Since 4 cups is equal to 1 quart and 1 quart is equal to 0.946 liters, we can convert the volume of the soup from cups to liters using the following conversion:

volume (L) = (1 c) * (4 c/1 qt) * (0.946 L/1 qt) = 3.784 L

Finally, we can use the number of moles of sodium and the volume of the soup to calculate the molarity of sodium in the soup using the following formula:

molarity = (moles Na) / (volume (L)) = 38.8 moles Na / 3.784 L = 10.3 M

Therefore, the molarity of sodium in the soup is approximately 10.3 M.

This is because molecular compounds are composed of non-metals, while ionic compounds are composed of a metal and a non-metal.

What are molecular compounds and ionic compounds?

Molecular compounds are compounds composed of molecules held together by chemical bonds. They are formed when two or more non-metals combine and form a covalent bond.

Ionic compounds are compounds composed of ions held together by electrostatic forces. They are formed when a metal and a non-metal combine and form an ionic bond.

g reffering to the periodic table, sort the following elements in order of increasing electronegativity: aluminum barium boron cesium calcium carbon fluorine

Answers

Increasing electronegativity for the following chemical would be: Florine > Carbon > Boron > Aluminum > Calsium > Cesium > Barium.

When atoms can attract electrons during chemical bonding, they are said to be electronegativity.

Electronegativity rises from left to right across the periodic table. The reason for this is that as the atomic number rises, there are more protons. Due to the growing size of the atoms, electronegativity decreases from top to bottom. As a result, fluorine is regarded as the element with the highest electronegative potential, whereas cesium has the lowest. The electronegativity of a halogen is thought to be high, while that of an alkali metal or an alkaline earth metal is thought to be low.

Which statements about hydrogen bonding are true? A. A hydrogen bond is formed by sharing electrons between atoms
B. A hydrogen bond also requires formation of ions.
C. A hydrogen bond is weak force between atoms in a molecule, but is of enormous importance in physiology.
D. A hydrogen bond is nothing but a different form of hydrogen ion.

Answers

A hydrogen bond is weak force between atoms in a molecule, but is of enormous importance in physiology.

What is Hydrogen Bonding?

Dipole-dipole interactions between molecules that do not include a covalent bond to a hydrogen atom are known as hydrogen bonds. The attraction between two incredibly electronegative atoms, such N, O, or F, and a hydrogen atom that is covalently bonded to one of them causes it to occur.

Any electronegative atom, such as oxygen, chlorine, or fluorine, may make up the other atom, whereas one of the atoms is hydrogen. Between molecules or between two different molecules, hydrogen bonds can develop between the atoms.
