Compare and contrast dehydration synthesis and hydrolysis

Both dehydration synthesis and hydrolysis deal with water but in opposite ways.Dehydration synthesis rips H2O away from two molecules so it can combine the two molecules. Hydrolysis breaks down molecules by reacting with water. An example of dehydration synthesis is maltose. Maltose is made by combining two glucose molecules using dehydration synthesis. Another example would be calcium carbonate. Calcium carbonate can form using dehydration synthesis. It starts as CaCO3 but as dehydration synthesisv occurs it loses a water molecule and becomes CaCO3 + H2O. An example of hydrolysis would be silicon dioxide. it occurs when Si-O-Si reacts with H2O to produce Si-OH + Si-OH.
