Answer: Zinc is a bluish-white metal used to galvanize iron, and is also found in alloys, batteries, and rubber. Sulfur is a yellow, brittle nonmetal; it can also be found in a powered form. Zinc and sulfur react with each other violently to produce zinc sulfide; the reaction is accompanied by a vigorous evolution of gas, heat, and light:
Zn(s) + S(s) ——> ZnS(s) [one of the easier
chemical equations
to balance!]
The products of the reaction also include small amounts of zinc oxide (ZnO) and sulfur dioxide (SO2).
This reaction produces enough hot gas to propel small rockets; this was one of the model rocket propellants described by Homer Hickam in his book Rocket Boys (Delacorte Pr; 1998) [filmed as October Sky (Universal Studios, 1999)].
In the first demonstration below, powdered zinc and sulfur are mixed in a porcelain evaporating dish and heated with a flame; the mixture burns with a yellowish-green flame, and leaves a residue of yellow zinc sulfide in the dish. In the second video clip, a larger sample is ignited in an evaporating dish, which shatters; and in the third clip, a similar mixture cracks a large porcelain crucible.
