1.	(i) Why hydrogen peroxide is stored in plastic containers, so in class container (ii) Give the general electronic condition of ladies and actinides.
Answer» Solution : (i) The AQUEOUS solution of hydrogen peroxide is spontaneously disproportionate to give oxygen. The reaction is slow but it is explosive when it is catalyzed by metal or alkali dissolved from glass. For this reason, its solution are stored in plastic bottles. `H_(2)O_(2(aq)) rarr H_(2)O_(1) + 1//2 O_(2(g))` 1. The electronic configuration of lanthanides is `4f^(1-14)5d^(10-1) 6s^(2)` 2. The electroniconfiguration of actinides is `5f^(1-14) 6D^(10-1)7s^2`
