Hydrogen Peroxide Hydrogen peroxide is the other important hydride of oxygen. The oldest method of its preparation is by the action of dilute sulphuric acid on barium peroxide
compound reacts with oxygen to form 2 oxide x and y. or analysis 1.535g of x yielded 1.365g of copper and 1.545g of y yielded 1.6 a.determine the chemical compound of x and y.b .
Chromium has the electronic configuration 4s 1 3d 5 rather than4s 2 , 3d 4 because: (1) 4s and 3d have the same energy (2) 4s has a higher energy than 3d (3)4s 1 is
