Hydrolysis:
Salt + Water --> Acid + Base
Na2CO3 + H(OH) --> H2CO3 + NaOH
Self ionization of water:
H2O + H2O --> OH- + H3O+
Your question is not very clear. Are you looking for examples of CHEMICAL reactions?
Dehydration reactions involve the removal of a water molecule from two adjacent molecules. This process forms a covalent bond between the molecules, typically resulting in the formation of a larger molecule.
Reduction reactions involve the gain of electrons by a molecule or atom. Displacement reactions involve the exchange of ions between two compounds. While reduction reactions can be involved in displacement reactions, they are not the same thing.
Bimolecular reactions involve two reactant molecules coming together to form a new product. This can include reactions such as addition, substitution, and some types of elimination reactions.
Two common types of reactions that are also redox reactions are combustion reactions and respiration. In combustion, a substance reacts with oxygen, resulting in the release of energy and the formation of oxidized products, such as carbon dioxide and water. Similarly, cellular respiration involves the oxidation of glucose in the presence of oxygen, producing energy, carbon dioxide, and water. Both processes involve the transfer of electrons between reactants, characterizing them as redox reactions.
It is a part of combination reactions. Two or more elements or compound react to form a largermolecule.Example:-NH3 + H2O -------> NH4OHCaO + CO2 ---------> CaCO3
Combustion reactions cannot involve a free element as a reactant since they involve the reaction of a fuel-rich substance with an oxidizing agent to produce heat and usually carbon dioxide and water. Two nonmetals combining to form a covalent bond also cannot involve a free element as a reactant.
Condensation reactions are so called because they involve the formation of a covalent bond between two molecules, resulting in the release of a small molecule such as water. This process "condenses" the two molecules together by removing a molecule of water.
A condensation reaction is the removal of a water molecule. A good example is the Joinging of Two monosaccharides to form a disaccharide.

Reduction reactions involve the gain of electrons by a molecule or atom. Displacement reactions involve the exchange of ions between two compounds. While reduction reactions can be involved in displacement reactions, they are not the same thing.
The three categories of chemical reactions are synthesis (combination), decomposition, and replacement (single or double displacement) reactions. Synthesis reactions involve the combination of two or more substances to form a new compound. Decomposition reactions involve the breakdown of a compound into simpler substances. Replacement reactions involve the exchange of ions between compounds.
Bimolecular reactions involve two reactant molecules coming together to form a new product. This can include reactions such as addition, substitution, and some types of elimination reactions.
The combination of two elements (a metal and a nonmetal) is always a redox reaction.
formation of new substances!!
The five main types of chemical reactions are synthesis, decomposition, single displacement, double displacement, and combustion. Synthesis reactions combine two or more elements or compounds to form a single product (e.g., 2H₂ + O₂ → 2H₂O). Decomposition reactions break down compounds into simpler substances (e.g., 2H₂O → 2H₂ + O₂). Single displacement reactions involve the exchange of ions between two compounds (e.g., 2AgNO₃ + Cu → Cu(NO₃)₂ + 2Ag). Double displacement reactions involve the exchange of ions between two compounds, forming two different products (e.g., NaCl + AgNO₃ → NaNO₃ + AgCl). Combustion reactions involve the reaction of a substance with oxygen to produce energy in the form of heat and light (e.g., C₃H₈ + 5O₂ → 4H₂O + 3CO₂).

There are multiple processes which can result in the formation of a water molecule. One example is the neutralization of an acid and a base which forms salt and water (e.g. HCl + NaOH ---> H2O +NaCl). In those types of reactions a water molecule is formed when a proton (aka an H+ cation) bonds with a hydroxide anion. There are several other water forming reactions. Another would be the dehydration synthesis of two monosaccharides.
