Synthesis Reactions
a chemical reaction in which 2 or more reactants combine to form a new product.represented by general formula:A + B AB or +
here, 2 reactants combine to form one product.

Example: Haber Process
An important product made by a synthesis reaction is ammonia NH3
It is used as a fertilizer to optimize crop yields, making paper, extracting nickel and zinc, in explosives, and cleaning products.Fritz Haber (German) patented a process for making ammonia:N2(g) + 3H2(g) 2 NH3(g)

Decomposition Reactions
a chemical reaction in which a compound breaks down into 2 or more products.General chemical equation:AB A + B or +
reactants will always be a compoundlike the reverse of a synthesis reaction

Example 1: Making Hydrogen
making hydrogen from waterthe development of hydrogen as a source of fuel, relies on the ability to make it from water in a process called electrolysis.2H2O (l) 2H2(g) + O2(g)electrical current is used to break the bonds between hydrogen and oxygen.

Example 2: TNT (explosive)
2C7N5N3O6(s) 3N2(g) + 5H2O(g) + 7CO(g) + 7C(s)
Rapid expansion of these gases pushes material away from the blast site, producing an explosion
