      K is in group 1. Therefore, the oxide will be K₂O.
      C is in group 4. Therefore, the oxide will be CO₂.
      Al is in group 3. Therefore, the oxide will be Al₂O₃.
      Si is in group 4. Therefore, the oxide will be SiO₂.
      Ba is in group 2. Therefore, the oxide will be BaO.

      (i) The general formula for oxides of 1st, 2nd, third and 4th group are R2O, RO, R2O3 and RO2 respectively in the Mendeleev’s Periodic Table, where R denotes the element.
      (ii) Since, Potassium (K) belongs to 1st group, thus, formula of its oxide would be K2O.
      (iii) Barium (Ba) belongs to 2nd group, thus formula of its oxide would be BaO.
      (iv) Aluminium (Al) belongs to the 3rd group, thus, formula of its oxide would be Al2O3.
      (v) Carbon (C) and Silicon (Si) belong to the 4th group, thus, formula of its oxide would be CO2 and SiO2 respectively.
      (vi) Thus, formula of oxides of the given elements would be K2O, CO2, Al2O3, SiO2 and BaO; respectively.
