Study Notes
Types of Chemical Reactions
-
Combustion Reaction
- Involves burning substances, releasing significant energy.
- Products commonly include carbon dioxide (CO2) and water (H2O).
- Examples include:
- C8H8 + O2 → CO2 + H2O
- C2H5OH + O2 → CO2 + H2O
-
Synthesis or Combination Reaction
- Involves combining two elements or compounds to form a larger compound.
- General formula: A + B → AB.
- Examples include:
- Mg + O2 → MgO
- MgO + CO2 → MgCO3
-
Decomposition Reaction
- Breaks down larger compounds into smaller components; the reverse of synthesis.
- General formula: AB → A + B.
- Heat can cause metal carbonates to decompose into carbon dioxide and a metal oxide.
- Examples include:
- MgCO3 → MgO + CO2
- HgO → Hg + O2
- H2O → H2 + O2
-
Single Replacement Reaction (Single-Displacement Reaction)
- Involves one element displacing another in a compound.
- General formula: A + BC → AC + B, where A and B are pure elements.
- Examples include:
- Zn + CuCl2 → ZnCl2 + Cu (Zinc displaces Copper)
- Br2 + NaI → NaBr + I2 (Bromine displaces Iodine)
- Fe + HCl → FeCl2 + H2 (Iron displaces Hydrogen)
- Non-metals can also displace metals.
-
Double Replacement Reaction
- Involves the exchange of ions between two compounds.
- General formula: AB + CD → AD + BC.
- Examples include:
- AgNO3 + NaCl → AgCl + NaNO3 (Silver pairs with Chloride)
- Types of double replacement reactions:
- Precipitation Reaction: Results in a solid product, e.g., HCl + NaOH → H2O + NaCl.
- Acid-Base Neutralization Reaction: Mixing an acid and a base yields water and a salt.
- Gas Evolution Reaction: Formation of gas, e.g., Na2S + HCl → NaCl + H2S.
- If products remain aqueous, no reaction occurs.
-
Context on Aqueous Solutions
- Aqueous phase composition is influenced by feedstock and reaction conditions.
- Functional groups of elements can be referenced using the periodic table.
- Common compounds include acetic acid, formic acid, glycolic acid, phenol, ethanol, methanol, ethylene glycol, and lactone.
