Summarizes the relationship between dehydration reactions and hydrolysis

Explanation:

Dehydration reaction is removal of water from a specie to give 2 distinct molecules. Dehydration reactions are common processes, the reverse of a hydration reaction. Examples of dehydrating agents are: sulfuric acid, alumina etc.

Hydrolysis reaction is the reaction of water molecules with a large molecule. Sometimes, this addition causes both substance and water molecule to split into two products, reactions like this, one fragment of the parent molecule gains a hydrogen ion.

The difference between dehydration synthesis and hydrolysis is that in one, bonds are being formed, while in the other bonds are being destroyed. In dehydration reaction, molecules are bonded together by removing water while in hydrolysis, water is added to the molecules in order to dissolve complex bonds.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
