Naming products

  1. Sodium chloride, water, carbon dioxide
  2. Lithium sulfate and copper (II) hydroxide
  3. Magnesium sulfate and water
  4. Iodine and sodium fluoride
  5. Magnesium sulfate and copper
  6. Carbon dioxide and water
  7. Magnesium nitrate and hydrogen

Balancing equations

  1. CuO + 2HCl → CuCl2 + H2O
  2. 2SO2 + O2 → 2SO3 Or: SO2 + ½O2 → SO3
  3. Ca(OH)2 + 2HCl → CaCl2 + 2H2O
  4. 2KClO3 → 2KCl + 3O2
  5. I2 + 2Na2S2O3 → 2NaI + Na2S4O6
  6. 5C + 2SO2 → CS2 + 4CO
  7. 2Al + 6HNO3 → 2Al(NO3)3 + H2 Or: Al + 3HNO3 → Al(NO3)3 + ½H2
  8. 4NH3 + 5O2 → 4NO + 6H2O Or: 2NH3 + 2.5O2 → 2NO + 3H2O

Redox and displacement

  1. Displacement
  2. Mg, Zn, Fe, Cu
  3. Mg is the strongest reducing agent – it is the most likely to lose electrons as it is the most reactive, therefore the most likely to donate electrons to another substance causing it to be reduced.
