1.
single product. For example, A + B → AB.
Decomposition Reactions: A single compound breaks down into two or more
2.
simpler substances. For example, AB → A + B.
Single Replacement (Displacement) Reactions: One element replaces another
3.
in a compound. For example, A + BC → AC + B.
Double Replacement (Metathesis) Reactions: Exchange of ions between two
4.
compounds. For example, AB + CD → AD + CB.
Combustion Reactions: A hydrocarbon reacts with oxygen, producing carbon
