Why would sand and water be an example of a heterogeneous mixture?

Answer: Sand and water be an example of a heterogeneous mixture because:-

  • The mixture does not have a uniform appearance.
  • The mixture does not maintain a uniform composition.
  • The sand stays suspended in the water.

Explanation:

A homogeneous mixture is a mixture in which solute particles are uniformly distributed throughout the solution. Whereas in a heterogeneous mixture particles of solute are not uniformly distributed throughout the solution.

For example, sand and water is a heterogeneous mixture because here sand particles are not uniformly distributed in the water. Hence, this mixture does not have uniform composition.

Also, after sometime the sand will deposit at the bottom of water, that is, sand will suspend in the water.

The mixture does not maintain a uniform composition. A homogeneous mixture really is the same anywhere you sample it, while sand generally settles out of water when given the chance and there's likely more sand at the bottom than at the top.

Marrrta [24]

Answer:

b C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻

e HC₂H₃O₂ + H₂O ⇄ H₃O⁺ + C₂H₃O₂⁻

f ka<<1

g. Weak acid molecules and water molecules

Explanation:

The water molecule could act as a base and as an acid, a molecule that have this property is called as amphoteric.

b The salt NaC₂H₃O₂ is dissolved in water as Na⁺ and C₂H₃O₂⁻. The reaction of the anion with water is:

<em>C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻</em>

Where the C₂H₃O₂⁻ is the base and water is the acid.

e. The reaction of HC₂H₃O₂ (acid) with water (base), produce:

<em>HC₂H₃O₂ + H₂O ⇄ H₃O⁺ + C₂H₃O₂⁻</em>

f. As the acetic acid (HC₂H₃O₂) is a week acid, the dissociation in C₂H₃O₂⁻ is not complete, that means that <em>ka<<1</em>

g. The ka for this reaction is 1,8x10⁻⁵, that means that there are more <em>weak acid molecules</em> (HC₂H₃O₂) than conjugate base ions. Also, the <em>water molecules </em>will be in higher proportion than hydronium ions.

I hope it helps!
