Study Notes
Types of Chemical Reactions
- Five general types of chemical reactions: Synthesis, Decomposition, Single Replacement, Double Replacement, and Combustion.
Synthesis Reactions
- General form: A + B >>>> AB.
- Examples:
- 2Na + Cl2 >>>> 2NaCl
- 2H2 + O2 >>>> 2H2O
Decomposition Reactions
- General form: AB >>>> A + B.
- Example: CaCO3 >>>> CaO + CO2.
Single Replacement Reactions
- General form: A + BC >>>> B + AC.
- Reaction between copper and silver nitrate produces:
- Copper(II) nitrate and Silver.
Double Replacement Reactions
- General form: AB + CD >>>> AD + CB.
- Definition: Two different compounds exchange positive ions forming two new compounds.
Balanced Double Replacement Example
- Lead(II) nitrate reacts with potassium iodide:
- Pb(NO3)2 + 2KI >>>> PbI2 + 2KNO3.
- Calcium carbonate reacts with hydrochloric acid produces:
- Calcium chloride (CaCl2) and carbonic acid (H2CO3).
Combustion Reactions
- Combustion of methane:
- CH4 + 2O2 >>>> CO2 + 2H2O.
Oxidation-Reduction Reactions
- Involves transfer of electrons from one reactant to another.
- Calcium is oxidized when it reacts with oxygen to form calcium oxide.
- The process of gaining electrons in a chemical reaction is referred to as Reduction.
