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>

If 0.97 moles of BaCl2 are dissolved in enough water to make a 1.2 liter soulution, what is the resulting molarity
Akimi4 [234]
         If    1.2 L of solution contains 0.97 mol
then let     1 L of solution contain  x   mol
     
       ⇒ (1.2 L) x  = (0.97 mol) (1 L)

                      x  = (0.97 mol · L)  ÷  (1.2 L)

                      x  = 0.8083 mol

Thus the molarity of the Barium Chloride solution is 0.808 mol / L   OR  0.808 mol/dm³.

what is the primary function of the cells that make up the majority of cells in the muscular system ​
ANTONII [103]

Answer:

The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
