TYPES OF REACTIONS

1. SYNTHESIS

1.1. A + B = AB

1.2. 2 Na(s) + Cl 2(g) → 2 NaCl(s)

1.3. Sodium + chlorine = Sodium Chloride

2. DECOMPOSITION

2.1. AB → A + B

2.2. 2 H2O(l) → 2 H2(g) + O2(g)

2.3. Water = Hydrogen + Oxygen

3. CORROSION

3.1. Metal breaking down due to chemical reactions with the environment

3.1.1. RUST

3.1.1.1. CORROSION PREVENTION

3.2. BENEFICIAL CORROSION

3.2.1. It is produced when metal corrodes and is very porous and readily flakes away from steel

3.2.1.1. Corrosion can be prevented by coating metals with rust inhibitors such as chrome, paint or plastic coating

3.3. When aluminum is exposed to air it corrodes and forms aluminum oxide.

3.3.1. Rusting in iron is caused by oxygen and water and salt speeds up the corrosion

3.3.1.1. Using corrosion resistant materials such as plastic or corrosion resistant alloys

3.4. When copper is exposed to air it develops a greenish patina which is so corrosion resistant that a copper roof can remain weatherproof for up to 75 years

4. SINGLE DISPLACEMENT

4.1. A + BC → AC + B

4.2. 2 AgNO3(aq) + Zn(s)→ 2 Ag(s) + Zn(NO3)2(aq)

4.3. Silver + Zinc = Silver + Zinc Nitrate

5. DOUBLE DISPLACEMENT

5.1. AB + CD = AD + CB

5.2. AgNO3(aq) + NaCl(aq) = AgCl(s) + NaNO(aq)

5.3. Silver Nitrate + Sodium Chloride = Silver Chloride + Sodium Nitrate

6. COMBUSTION

6.1. COMPLETE COMBUTION

6.1.1. INCOMPLETE COMBUSTION

6.2. CxHy + O2 = CO2 + H2O + Energy

6.2.1. C4H10(g) + 5 O2 (g) = 2 CO2(g) +5 H20(g) + CO(g) + C(s) + Energy

6.3. Hydrocarbon + Oxygen = Carbon Dioxide + Water + Energy

6.3.1. Butane + Oxygen = Carbon Dioxide + Water + Carbon Monoxide + Carbon

6.4. CH4(g) + 2 O2(g) = CO2(g) + 2 H2O(g) + Energy

6.4.1. A + O2 = AO

6.5. Methane + Oxygen = Carbon Dioxide + Water + Energy

6.5.1. Element + Oxygen = Oxide
