Molar heat (or enthalpy) of formation.
The products of a binary compound during decomposition are usually the elements that formed the compound initially. For example, if a binary compound AB decomposes, it can form elements A and B.
The amount of heat involved in the synthesis of 1 mole of a compound from its elements, with all substances in their standard states at 25 °C, is called the standard enthalpy of formation (ΔH°f). This value is crucial in thermodynamics and helps in calculating the heat changes during chemical reactions. It is typically expressed in kilojoules per mole (kJ/mol).

During a chemical reaction, a compound is separated into its individual elements through the breaking of chemical bonds. This process involves the rearrangement of atoms to form new compounds or elements.
In synthesis reactions, two or more substances combine to form a new compound. In decomposition reactions, a single compound breaks down into simpler substances. In exchange reactions, atoms or ions in different compounds switch places to form new compounds. The key is to identify the number of reactants and products and observe how the elements rearrange during the reaction.
A synthesis reaction is where two (or more) chemicals or elements combine to create one new product. A decomposition reaction is the opposite meaning it is when one compound is broken down into the 2 (or more) compounds/elements it is made up of. Both of these refer to compounds, not mixtures. Mixtures cannot have synthesis or decomposition reactions. The difference between a compound and a mixture is that a compound is chemically bonded together at the atomic level while a mixture is just mixed together.

The formation of water can be classified as a combustion reaction because hydrogen is heated in oxygen, and it is considered a synthesis reaction because two elements - hydrogen and oxygen - combine to form 1 compound - water.
Atoms of different elements unite during chemical changes to produce at least one chemical compound.
That is a condensation reaction. Added: Dehydration is also a possible term.
The elements are combined to form a coherent whole in the synthesis stage of the dialectic process. This stage involves reconciling the contradictions between the thesis and antithesis to create a new and higher level of understanding or resolution.
None are. The elements are not decomposed: the water is. The elements released by the reaction are hydrogen and oxygen.
