Question

short note on oxidation, sublimation,easterification

Answer 1

Oxidation is any chemical reaction that involves the moving of electrons. Specifically, it means the substance that gives away electrons is oxidized.

When iron reacts with oxygen it forms a. chemical called rust because it has been oxidized.   Sublimation is the phase transition of a substance directly from the solid to the gasphase without passing through the intermediate liquid phase.[1] Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram,  Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form anester as the reaction product. Esters are common in organic chemistry and biological materials, and often have a characteristic pleasant, fruity odor.
