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