Solvation is the process of dissolving.

Dissociation is the separation of a substance into charged components during dissolution.

<h3>What is the difference between dissolving and dissociating?</h3>

Dissolution (dissolving), which simply refers to becoming solvated by the solvent, is a subset of dissociation, which is particularly the separation of two charged ions in solution. When the solvent completely envelops each individual solute molecule, solvation takes place. By definition, something that is dissociated in a solvent must be dissolved in it. For instance, the salt dissociates in water, which is how it dissolves in water. In water, ethanol dissolves but does not dissociate; it remains ethanol.

<h3>How does Van't Hoff's factor work?</h3>

The Van't Hoff factor is a tool used to compare the real number of moles of solute injected to create a solution to the apparent amount produced by colloidal characteristics.

<h3>What is the Van't Hoff factor's value?</h3>

Van't Hoff factor's value is:-

  • No association or dissociation                  i=1
  • Dissociation                                             i<1
  • Association                                               i>1

One meter is equal to 10 9 nanometers. How long in meters is 670 nanometers? 6.70 × 10 –7 m
Mila [183]

Answer:

The answer to your question is: the first option

Explanation:

Meter is a unit of length in the SI, international system of units. Its symbol is m.

Nanometer is equivalent to 10⁻⁹ meters, as its name says it is used to measure  extremely small particles.

-To solve this problem we use a rule of three.

                             1 meter      ⇒     10⁹ nanometers

                             x meters    ⇒     670 nanometers

Simplify

                            x = (670 x 1)/( 10⁹)              

                            x = 6.7 x 10 ⁻⁷ meters

  • An ionic compound will not conduct electricity as a solid.
  • It will conduct electricity when melted.
  • Some ionic compounds are soluble. Their solutions in water also conduct electricity.
<h3>Explanation</h3>

A substance should contain charged particles that are free to move around in order to conduct electricity.

Ionic compounds contain an ocean of ions. They carry either positive or negative charges. Attractions between them hold them in a rigid lattice under the solid state. Those ions are unable to move. The ionic compound can't conduct electricity.

Melting the ionic compound will break the lattice. Those ions are now free to move to conduct electricity. Dissolving the compound in water will also free the ions. As a result, those solutions will also conduct electricity.

Conductivity under different states distinguishes between ionic compounds, molecular compounds, and metals.

  • Ionic compounds conduct electricity when melted but not as a solid.
  • Molecular compounds have no charged particles. They do not conduct electricity even when melted.
  • Valence electrons in metals are free to move both when the metal is a solid and when it is melted. Metals conduct electricity under both solid and liquid states.
