balance it last

Balance ______ as a unit

polyatomic ions

Synthesis/combination

A+B → AB

Decomposition

AB → A+B

Displacement (I): If A is a metal, A

A+BC → _C+B

Displacement (II): If A is a nonmetal, C

A+BC → _ + BA

Double-displacement

AB+CD → AD+CB

Combustion

C_ₙH_ₙ + O_₂ → CO_₂+H_₂O

metal ______+ acid → salt + ____(g) + H₂O (l)

Gas Forming reactions (II): sulfite, SO₂

metal _______ + acid → salt + ____(g) + H₂O(l)

Gas Forming reactions (III): ammonium, NH₃

_______ salt + base → salt + ____(g) + H₂O(l)
