Iron-chlorine reaction. Iron (Fe) producing flames as it reacts with chlorine gas (Cl2) in a gas jar, forming iron (III) chloride (FeCl3, yellow-brown solid). The reaction starts once the iron (in the form of iron wool) has been heated to glowing red and placed in the gas jar. This is an exothermic reaction (one that releases heat).
