Why silent electric discharge is used to convert `O_(2)` into `O_(3)` ?

When O_2 is converted into O_2^(+)

Name two reagents which can be used to convert gtC = O to gt CH_(2) group.

An element occupies group No.16 and period number 2. This element on passing through silence electric discharge forms (A). (A) also reacts with lead sulphide and forms (B). (A) also reacts with BaO_(2) and forms (C). It reacts with H_(2)O_(2) and forms (D). Identify the dement (A), (B), (C) and (D).

Quantity of charge in Coulomb required to convert 1 mole Cr_2O_7^(2-) & Cr^(3+) .

For the reaction 2O_(3)(g)rarr3O_(2)(g) , the experimentally obtained rate equation , rate =k=([O_(3)]^(2))/([O_(2)]) . What is the overall order of this reaction? What is the order of the reaction with respect to O_(3) and O_(2) ?

Which organic reagent is used for the manufacture of H_(2)O_(2) ?

Two discharge tubes containing H_(2) and O_(2) gas respectively are subjected to electrical discharge at low pressure. Will there by any difference in the nature of cathode rays annd anode rays formed inside the tube?

Which one is more basic and why-mGo & Al_(2)O_(3) ?
