  1. potassium chromate and lead nitrate produces lead chromate and potassium nitrate(CD-ROM 4-10)
    K2CrO4 (aq) + Pb(NO3)2 (aq) - > PbCrO4 (s) + 2 KNO3 (aq)

  2. lead nitrate and potassium iodide produces lead iodide and potassium nitrate(CD-ROM 4-11)
    Pb(NO3)2 (aq) + 2 KI (aq) -> PbI2 (s) + 2 KNO3 (aq)

  3. silver nitrate and sodium chloride produces silver chlroide and sodium nitrate(CD-ROM 4-12)
    AgNO3 (aq) + NaCl aq) - > AgCl (s) + NaNO3 (aq)

  4. iron (III) Ions + Sodium hydroxide produces iron (iii) hydroxide and sodium ions(CD-ROM 4-12)
    Fe3+ (aq) + 3 NaOH (aq) - > Fe(OH)3 (s) + 3 Na1+(aq)

  5. calcium carbonate and hydrochloric acid produces carbon dioxide, calcium chloride, and water(CD-ROM 4-14)
    CaCO3 (s) + 2 HCl (aq) -> CaCl2 (aq) + H2CO3(aq)
    H2CO3(aq)+ -> CO2 (g) + H2O (l)

  6. magnesium + hydrochloric acid produces magnesium chloride and hydrogen gas(CD-ROM 4-14)
    Mg (s) + 2 HCl(aq) -> MgCl2(aq) + H2 (g)

  7. zinc and nitric acid produces nitrogen dioxide, zinc ions, and water (CD-ROM 4-14)
    Zn (s) + 4 HNO3 -> Zn2+(aq) + 2 NO2 (g) + 2 H2O (l) + 2 NO31+ (aq)
