How do you Identify Chemical Reactions.

By studying the following chemical reaction we can identify chemical reactions,

The vast number of chemical reactions can be classified in any number of ways. Under one scheme they can be categorized either as oxidation-reduction (electron transfer) reactions or non-oxidation-reduction reactions. Another completely different but common classification scheme recognizes four major reaction types:

(1) combination or synthesis reactions

(2) decomposition reactions

(3) substitution or single replacement reactions

(4) metathesis or double displacement reactions
