It is so hot in the blast furnace that carbon monoxide is the reducing agent which reduces the iron(III) oxide. The equation for the reduction of iron(III) oxide in the blast furnace is: ...

Mars is the Red Planet, but turns out the moon has the makings of a reddish cast, too. Yes, scientists have found rust on the moon. The question is: why?

Iron oxide, aluminum, and a catalyst are placed in a flowerpot. The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration ...

To make a safe, portable form of heating to take to the rest of the team working up on the glacier. All combustion reactions (such as the burning of coal) are exothermic. Incredibly, the reaction ...

During the Proterozoic era, oxygen produced by photosynthesizing bacteria collects in the oceans and then in the atmosphere. Iron present in exposed rocks reacts with this oxygen, and rust colors ...
