This is chemistry: 2 questions having to do with particles
PilotLPTM [1.2K]

Answer 1 :

Image 1 shows : Liquid phase

Image 2 shows : Gas phase

Image 3 shows : Solid phase

Image 4 shows : Solid phase

  • Solid phase : In this state, the molecules are closely and tightly packed. There is no vacant space present in it.
  • Liquid phase : In this state, the molecules are loosely packed and there is an intermediate vacant space present in it.
  • Gas phase : In this state, the molecules are very loosely packed and there is a lot of vacant space present in it.

Answer 2 :

Liquid to gas : Evaporation

Solid to gas : Sublimation

Gas to solid : Deposition

Solid to liquid : Melting

Liquid to solid : Freezing

Gas to liquid : Condensation

Explanation :

  • Evaporation : It is a type of vaporization process in which a liquid changes into gas phase by providing heat.
  • Sublimation : It is a process in which a solid changes directly into gas phase without passing through a liquid phase.
  • Deposition : It is a process in which a gas transforms directly into a solid phase without passing through a liquid phase.
  • Melting : It is a process in which a solid changes into liquid phase by providing heat.
  • Freezing : It is a process in which a liquid transform into a solid phase.
  • Condensation : It is a process in which a water vapor(gas) changes into liquid state.

PLEASE ANSWER QUICKLY!!!in an ionic compound , which ions are attracted to each other?
Sauron [17]

Answer:

Oppositely charged ions attract each others i.e, positive and negative ions

Explanation:

Ionic Compound:

Ionic compounds consist have ionic bonds. It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference.

The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.  Sodium have one valance electron while chlorine have 7 valance electrons. In order to complete the octet chlorine require one electron while sodium need to lose its one electrons. That's why when both atom combine sodium lose its electron and becomes positive ion i.e cation while chlorine accept its electron and becomes negative ion called anion and bond between them is ionic bond. The electrostatic forces created between both atoms.
