oxygen, and hydrogen. Its formula is written: H2SO4. So we write Mg plus H2SO4. An arrow shows the direction of the reaction, just like in a word equation. Then the product hydrogen is written as ...

When it is, an electrochemical reaction takes place between the hydrogen and oxygen that directly converts chemical energy into electrical energy. Various types of fuel cells exist, but the one ...

When yeast was added to hydrogen peroxide, 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.

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 ...
