Use Mendeleev's Periodic Table to predict the formulae for the oxides of the following elements: K, C, Al, Si, Ba. |
|
Answer» Solution :K is in group 1, Therefore the oxide will be `K_2O`. C is an group 4, Therefore the oxide will be `CO_2`. Si is in group 4, Therefore the oxide will be `SiO_2`. Al is in group 3, Therefore the oxide will be `AI_2 O_3`. BA is in group 2, Therefore the oxide will be `BAO`. |
