Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

The cell produces electricity through chemical reactions between hydrogen peroxide and ... variety has just the opposite concentration – 3 percent water and 97 percent hydrogen peroxide – and it has ...

Some chemical reactions change temperature ... a chemical in the yeast causes a reaction in which the hydrogen peroxide breaks apart to form oxygen gas and water. The oxygen was in the bubbles you saw ...

Add it to a spray bottle using one part hydrogen peroxide and two parts water. Remember that you should spot test the ...

water and oxygen. If this reaction happens too slowly then hydrogen peroxide can build up and poison the cell. Chemical reactions can be speeded up by increasing the temperature because more ...
