2. Types of Redox Reactions Direct Combination
OXIDATION - REDUCTION
Types of Redox Reactions
Direct Combination
S (s) + O2 (g) -> SO2 (g)
2 Al (s) + 3 Br2 (l) -> 2 AlBr3 (s)

3. Decomposition 2HgO (s) -> 2 Hg (l) + O2 (g)

4. Single Replacement
Cu (s) AgNO3 (aq) -> Cu(NO3)2 (aq) Ag (s)
Net equation:
Cu (s) Ag+ (aq) -> Cu+2 (aq) Ag (s)

5. Cu (s) + Mg2+ (aq) -> Na (s) + H2O (l) ->
Activity Series – a listing that ranks metals according to their relative reactivity

9. Application of Redox Reactions
Preventing corrosion can coat iron w/ oil, plastic or a less reactive metal to prevent rust - Fe2O3 Iron(III) oxide coated with Zn is galvanized steel
Bleaching used eliminate unwanted color from fabrics & other materials - (Cl2, NaClO, H2O2)

10. Fuels and explosives – release energy when oxidized –
Fuels and explosives – release energy when oxidized – nitroglycerine - C3H5(NO3)3
combustion => hydrocarbon + O2 → CO2 + H2O + heat
Photography –
2 Br- → Br20 + 2e oxidation
2 Ag+ + 2e → Ag reduction

11.  Determining the oxidizing agent and what is the reducing agent Worksheet

12. Balancing RedOx Equations
the fundamental principle in
balancing RedOx equations is that the
number of electrons lost in the oxidation
reaction equals the number of electrons gained in the reduction reaction.
