Study Notes
Combustion Reactions
- Ethane (C2H6) combusts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O) in the reaction: 2 C2H6 + 7 O2 → 4 CO2 + 6 H2O.
- Methane (CH4) also undergoes combustion yielding CO2 and H2O: CH4 + O2 → CO2 + 2 H2O.
- Pentane (C5H12) is another hydrocarbon that combusts to form CO2 and H2O: C5H12 + 8 O2 → 5 CO2 + 6 H2O.
Synthesis Reactions
- Phosphorus (P4) reacts with oxygen (O2) to form diphosphorus pentoxide (P2O5): P4 + 5 O2 → 2 P2O5.
- Magnesium (Mg) combines with oxygen (O2) to create magnesium oxide (MgO): 2 Mg + O2 → 2 MgO.
Single Replacement Reactions
- Zinc (Zn) displaces hydrogen when reacting with hydrochloric acid (HCl): Zn + 2 HCl → ZnCl2 + H2.
- Aluminum (Al) reacts with hydrochloric acid to yield aluminum chloride (AlCl3) and hydrogen: 2 Al + 6 HCl → 2 AlCl3 + 3 H2.
- Calcium (Ca) reacts with hydrochloric acid, producing calcium chloride (CaCl2) and hydrogen: Ca + 2 HCl → CaCl2 + H2.
- Silver (Ag) displaces sodium in sodium nitrate (NaNO3) to form silver nitrate (AgNO3): NaNO3 + Ag → AgNO3 + Na.
Double Replacement Reactions
- Iron(III) chloride (FeCl3) reacts with ammonium hydroxide (NH4OH) to form iron(III) hydroxide (Fe(OH)3) and ammonium chloride (NH4Cl): FeCl3 + 3 NH4OH → Fe(OH)3 + 3 NH4Cl.
- Aluminum iodide (AlI3) and mercury(II) chloride (HgCl2) react to produce aluminum chloride and mercury(II) iodide: 2 AlI3 + 3 HgCl2 → 2 AlCl3 + 3 HgI2.
- Hydrochloric acid reacts with sodium hydroxide (NaOH) to produce sodium chloride (NaCl) and water: HCl + NaOH → NaCl + H2O.
Decomposition Reactions
- Potassium chlorate (KClO3) decomposes into potassium chloride (KCl) and oxygen: 2 KClO3 → 2 KCl + 3 O2.
- Water (H2O) breaks down into hydrogen (H2) and oxygen (O2): 2 H2O → 2 H2 + O2.
- Hydrogen peroxide (H2O2) decomposes to form water and oxygen: 2 H2O2 → 2 H2O + O2.
- Calcium chlorate (Ca(ClO3)2) decomposes into calcium chloride (CaCl2) and oxygen: Ca(ClO3)2 → CaCl2 + 3 O2.
