... What is percentage yield and why do we use it? In chemical reactions we rarely, if ever, get the amount/quantity of products we calculate from a (balanced) chemical equation. The reasons for this can be: • at the end of the reaction there may be reactant left unconverted to product (see excess) • ...

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.
