=__Synthesis Reaction__=

Synthesis is also known as combination where two types of molecules come together to form one. EX: A + B ---> AB -- A and B are the reactants and AB is the product of the compound.

»These are some examples:

Mg + O2 ---> MgO H2 + O2 ---> H2O K + Cl2 ---> KCl Fe + O2 ---> Fe2O3

»Synthesis can also be two compounds making a more complex compound (or a compound and an element joining together) as in these examples:

CaO + CO2 ---> CaCO3 Na2O + CO2 ---> Na2CO3 KCl + O2 ---> KClO3 Ba(ClO3)2 ---> BaCl2 + O2

»Synthesis reactions are the reverse of decomposition, you might ask if the decomposition categories apply, just in reverse.

1) Direct union of two elements will produce a binary compound. 2) Metallic oxides and carbon dioxide react to produce carbonates. 3. Binary salts and oxygen react to produce a chlorate.
