Details of the chemical reaction of oxygen with the [Fe-S] cluster reveal how this cofactor is used for oxygen sensing.

Let me show you one of my favourite reactions. This fine powder is iron. When we sprinkle it over the flame, it lights up like a sparkler. The iron is reacting with the oxygen in the air to make a ...

The substance that reacts with the candle wax is oxygen. It comes from the air. Putting the jar over the candle keeps oxygen from outside the jar from getting in. The reaction can only use the oxygen ...

Watch this video to see a practical investigation into the reactivity of iron. Metals can react with water, acid and oxygen. The reactivity of the metal determines which reactions the metal ...

All combustion reactions (such as the burning of coal) are exothermic. Incredibly, the reaction between iron and moist air ... the chemical removal of oxygen from, or the addition of hydrogen ...
