Reaction Prediction Types

I. Decomposition

A. Compound à 2 Compounds

· Metallic carbonate à metallic oxide + CO2

· Metallic hydroxide à metallic oxide + H2O

· Oxyacids à non-metallic oxide + H2O

B. Compound à 1 Compound + 1 Element

· Metallic chlorate à metallic chloride + O2

C. Compound à 2 elements

· Metallic oxide à metal + O2

· H2O (electrolysis) à H2 + O2

· Metallic halide (electrolysis) à metal + halogen

II. Composition (synthesis/addition/combination)

Use activity series sheet and opposite of decomposition reactions

III. Combustion

Organic compound + O2 à CO2 + H2O

IV. Double Replacement

+ ions switch places

V. Single Replacement

A. Use the activity series sheet!

B. Halogen + compound à different halogen + compound

C. Metal + compound à different metal + compound

D. Replacement of hydrogen in water by metals

· Group A metals + H2O à H2 + metallic hydroxide

· Group B metals + H2O à H2 + metallic oxide

· Group C metals + H2O à NR

E. Metal + acid à H2 + compound
