668AARCK Reaction Types Get out a piece of paper for notes, we are starting reaction types

Synthesis Whenever two or more substances combine to form a single product Ex. 4Fe +3O 2  2Fe 2 O 3

Decomposition A compound that breaks down into two or more simpler substances Ex. NH 4 NO 3 (s)  N 2 O(g) + 2H 2 O(g)

Single displacement Reaction One element takes the place of another in a compound Ex. Fe + CuSO 4  FeSO 4 + Cu

Double displacement Reaction The positive portions of the two ionic compounds are interchanged. Ex. Pb(NO 3 ) 2 + 2KI  PbI 2 + 2KNO 3

Combustion Occurs when a substance rapidly combines with oxygen to form one or more oxides Ex. 2C 2 H 2 + 5O 2  4CO 2 +2H 2 O ctables.com/id/Alc ohol-Rocket- Engine/
