... This explores the trend in oxidising ability of the Group 7 elements (the halogens) fluorine, chlorine, bromine and iodine. We are going to look at the ability of one halogen to oxidise the ions of another one, and how that changes as you go down the Group. We are going to look at the reactions betw ...

In the first two cases, in the proton is trans- (structure 1a) and cis- (structure 1b) position with O-O bond of ozone. Oxygen-oxygen bonds in ozone are unequal. Calculated dipole moment of ozone is 0. ...

Electrolysis of water
Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.
