It continues the trend of the highest oxides of the Period 3 elements towards being stronger acids. Chlorine (VII) oxide reacts with water to give the very strong acid, chloric (VII) acid - also known as perchloric acid. The pH of typical solutions will, like sulphuric acid, be around 0. Cl 2 O 7 + H 2 O 2HClO 4.

The formula for aluminum oxide is Al_2O_3. The correct answer is Al_2O_3. Let us see how we got the answer; Look at the electronic arrangement of Al and O atoms. Al ( Z= 13) has 13 electrons with following electronic configuration. 1s^22s^22p^63s^23p^1 It loses three electron in its 3s and 3p subshell to achieve stability and forms ion Al^(3+). Al^(3+) = …

The formula of aluminium oxide is given as Al 2 O 3. How is this formula generated? First of all, we have to consider that aluminium is a metal and Oxygen is a non-metal making it an ionic compound. There is some charge in the aluminium and oxygen ions. Aluminium has a +3 charge whereas oxygen has -2 charge. On applying the criss-cross method ...
