Like sodium and chloride in table salt, the potassium atom is bonded to the oxygen atom in potassium hydroxide by the transfer of an electron from the potassium atom to the oxygen atom to create a(n) bond. ionic covalent metallic compound

ionic

Explanation: Ionic bond is formed by the complete transfer of electrons from a metal to a non metal.

In potassium hydroxide there is complete transfer of electrons from potassium to hydroxide.

Covalent bond is formed by sharing of electrons. Metallic bond is formed in metals.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
