Classic Thermite Reaction

A thermite reaction is a really good example of a redox reaction in action! Here is how to do the classic demo: Key Takeaways Fe2O3 (s) + 2 Al (s) → Al2O3 (s) + 2 Fe (s) The reaction needs high activation energy. Once it is running it becomes self-sustaining Thermite reactions produce an extreme… Continue reading Classic Thermite Reaction

Sulfur and Iron Reaction

A stoichiometric mixture of iron and sulfur reacts in a sparkling, glowing way – and can be started by a red-hot steel rod! Key Takeaways Fe(s) + S(s) –> FeS(s) The reaction is highly exothermic and releases 100kJ per mole of Iron Sulfide Equipment & Chemicals 10g of iron powder 5g of sulfur powder long… Continue reading Sulfur and Iron Reaction
