Question

cite some evidence to prove that electrolysis is a chemical change​

Answer 1

Water can also undergo a chemical change.Watermolecules can be broken down into hydrogen and oxygen molecules by a chemical reaction called electrolysis.When an electric current is passed throughliquid water (H2O),it changes the water into twogases—hydrogen and oxygen.The molecules ofwaterbreak apart into individual atoms.These atoms thenrecombine into hydrogen molecules (H2) and oxygenmolecules (O2).The original material (water) changesinto different substances through a chemical reaction.Hydrogen and oxygen are used as rocket fuel for thespace shuttle.During liftoff,liquid hydrogen and liquidoxygen are combined in a reaction that is the opposite ofelectrolysis.This reaction produces water and a largeamount ofenergy that helps push the shuttle into orbit.

Answer 2

Answer:

Water can also undergo a chemical change. Watermolecules can be broken down into hydrogen and oxygen molecules by a chemical reaction called electrolysis. When an electric current is passed throughliquid water (H2O),it changes the water into twogases—hydrogen and oxygen.
