- - - - Two compounds forming a new compound.
        
        Two compounds reacting to form a new compound involving the reaction of metal or non-metal oxides and water
        
        /
        
        Metal Oxide: a compound with a metal and oxygen.
        
        When a metal oxide reacts with water, it forms a metal hydroxide which produces a base
        E.g. Na2O(s) + H2O(l) → NaOH(aq).
        
        Non-metal Oxide: a compound with a non-metal and oxygen.
        
        When a non-metal oxide reacts with water, it forms an acid.
        E.g. CO2 (g) + H2O(l) → H2CO2 (aq)
      - An element and a compound forming a new compound.
        
        2SO2 + 3O2 → 2SO3
        
        Can be difficult to predict the product for as they often involve covalent compounds, which can form in many ratios
      - Two elements forming a compound
- - - - Breaks down into Metal Oxide and CO2
        
        e.g CaCO3 --> CaO + CO2
    - - Binary compounds tend to break down into their substituent elements e.g H2O --> H2 + O2
    - - Breaks down into Metal oxide and water
        
        e.g Ca(OH)2 --> CaO + H2O
    - - Breaks down into Metal Nitrite and Oxygen
        
        e.g 2NaNO3 --> Na + NO3
- - - - Equation: Hydrocarbon + Oxygen = Carbon Dioxide + Water + Energy
  - - - Equation: 2H2 + O2 = 2H2O
- - - - Al(s) + FeCl2 → Fe(s) + AlCl3
      - Displacement involving metals can only occur if said metal is more reactive than the one it replaces (Activity Series)
    - - Cl2 + 2NaBr(aq) → 2NaCl(aq) + Br2 (l)
    - - Mg + HCl --> MgCl2 + H2
      - Some metals may not be reactive enough to displace Hydrogen in water and/or Acids (Activity Series)
- - - - In double displacement reaction, precipitates can form which is an insoluble solids that are produced during the double displacement reaction.
    - - If Carbonic Acid is included in the double displacement reaction, it will produce Carbon Dioxide gas.
        
        CH3COOH(aq) + NaHCO3(aq) ⟶ NaCH3COO(aq) + H2O(ℓ) + CO2(g)
      - If Ammonium Hydroxide is included in the double displacement reaction, it will produce Ammonia gas.
        
        NH4Cl(aq) + NaOH(aq) ⟶ NaCl(aq) + H2O(ℓ) + NH3(g)
    - - Neutralization Reaction (H+(aq) + OH-(aq) ⟶ H2O(aq)
        
        Acid + Base = Water & Salt
