Answer:

The average kinetic energy of the gas is 4.678 kJ/mol.

Explanation:

Average kinetic energy of the gas id defined as measure of an average kinetic energy possessed by each particle of the gas.

It is given as:

K=\frac{3}{2}RT (Average kinetic energy per mole)

K=\frac{3}{2}kT (Average kinetic energy per molecule)

R = Universals gas constant8.314 J /mol K

T = temperature of the gas

k = Boltzmann constant = 1.38\times 10^{-23} J/K

The average kinetic energy of 1 mole of gas at 102°C:

T = 102°C = 375.15 K[/tex]

K=\frac{3}{2}\times 8.314 J/mol K\times 375.15 K=4,678.49 J/mol=4.678 kJ/mol

The average kinetic energy of the gas is 4.678 kJ/mol.

<span>R= 8.314 J/mol K T= 273 + 102 = 375K</span><span>

= (3/2) x 8.314 x 375 = 4680 J/mol</span>

Which compound will have the larger rf value on a si02 tlc plate using 10 % ethyl acetate/ hexane as eluent: 3-decanone or 3-dec
Hatshy [7]

The formula of determining the R_f value is:

R_f = \frac{distance travelled by the solute}{distance travelled by the solvent}

where both the distance are measured from the common origin.

10 % ethyl acetate/ hexane means it has 10 % ethyl acetate and 90 % hexane which are non-polar in nature. Hence, the non-polar compound will travel farther in the TLC plate along with the eluent and the polar compound will travel less as they remain attracted to the polar adsorbent SiO_2.

Among 3-decanone and 3-decanol, 3-decanone will have high R_f as it is non-polar.

Among toluene and benzoic acid, toluene will have high R_f as it is non-polar.

Among cyclooctane and cyclooctanone, cyclooctane will have high R_f as it is non-polar.

Describe the differences between bonding in an ionic compound and bonding in a covalent molecule.
Fudgin [204]

a covalent bond and an ionic bond. An ionic bond if formed from the transfer of electrons from the outer shell of atoms. ... An example of this is NaCl, where the sodium atom becomes Na+ due to the loss of electrons, and the chlorine atom becomes the negatively charged chloride (Cl-).
