Sulfur and flash

Sulfur comes in very easily in the reaction. When connecting other elements to sulfur, a flash often occurs. Thus, for example, when a mixture of sulfur and lead dioxide is triturated, a flash occurs in the mortar:

Pb2 + S = Pb + SO2.

In the grinding of lead dioxide with red phosphorus there is also a flash:

5PbO2 + 4P = 2P2O5 + 5Pb.

For safety reasons, small amounts of these substances must be taken for such experiments.

Sulfur and flare are non-polar concepts when mixing equivalent amounts of fine magnesium shavings and sulfur. This mixture flashes brightly and very strongly.

Mg + S = MgS.

It turned out that sulfur interacts poorly with aluminum chips. The mixture almost does not burn. But, if you use aluminum powder ("silver"), then there will be a bright flash.

2Al + 3S = Al2S3

A strong flash will also occur as a result of ignition of a mixture of stoichiometric amounts of sulfur and zinc dust. In this case, red-hot pieces of white zinc sulphide, as well as starting materials that did not have time to react, fly away in all directions.

Zn + S = ZnS.
