Hydrogen peroxide that antiseptic liquid that usually comes in a brown bottle and bubbles up when you put it on a cut is a chemical compound that s made of two hydrogen and two oxygen molecules bonded together.
H 2 o 2 looks like ordinary water h 2 o but the addition of that extra oxygen atom turns the molecule into an extremely powerful oxidizer.
