Answer:

A solution is a heterogeneous mixture

Explanation:

This statement that a solution is a heterogeneous mixture is completely and totally wrong.

A solution is a homogeneous mixture.

Homogeneous mixtures have their constituents existing in just one phase.

  • It is a homogeneous mixture of solutes and solvents.
  • In a solution, the solutes particles are distributed uniformly in the solvent.
  • The solute is the substance that is dissolved to make the solution.
  • Solutes are usually present in a small amount than the solvent.
  • The solvent acts as the dispersing medium which allows the solute to go into the solution.
  • The solute can be solid, liquid or gas.

Using the van der Waals equation, the pressure in a 22.4 L vessel containing 1.00 mol of neon gas at 100 °C is ________ atm. (a
svetoff [14.1K]

Answer:

The answer to your question is        P = 1.357 atm

Explanation:

Data

Volume = 22.4 L

1 mol

temperature = 100°C

a = 0.211 L² atm

b = 0.0171 L/mol

R = 0.082 atmL/mol°K

Convert temperature to °K

Temperature = 100 + 273

                      = 373°K

Formula

               (P + \frac{a}{v^{2}} )(v - b) = RT

Substitution

               (P + \frac{0.211}{22.4})(22.4 - 0.0171) = (0.082)(373)

Simplify

               (P + 0.0094)(22.3829) = 30.586

Solve for P

                           P + 0.0094 = \frac{30.586}{22.3829}

                           P + 0.0094 = 1.366

                                 P = 1.336 - 0.0094

                                P = 1.357 atm

Answer:

25.30 gram

Explanation:

No of moles = given mass / molar mass

No of moles = 63.17/80.06

0.7890 moles

Mass of sulphar = no of moles× molar mass of sulphar

Mass of sulphur = 0.7890×32.065

25.30 gram
