  2. The reaction between fresh zinc powder and sulfur can give a very bright flash. On this scale it is harmless, but makes an impressive comparison. If the reaction is not impressive, the zinc has oxidised.

  3. REAGENTS. powdered sulfur, S (1 g) 8. powdered zinc, Zn (6 g) PREPARATION Place insulating mat and burner into the otherwise empty fume hood. Using a small evaporating basin, weigh out 6 g of zinc and 1 g of sulfur. With a small spatula mix the two powders until the colour of the mixture is uniform.

  4. Either reaction is valid for representing the reaction between zinc and sulfur. The important thing is that both equations stipulate the same stoichiometry (one atom of zinc for one atom of sulfur).

  5. 30 cze 2023 · Metallic zinc reacts with weak acids very slowly. Sulfur has a strong affinity for zinc. When heated, the two powders react explosively to form zinc sulfide. Zinc sulfide is used to make television screens and fluorescent light bulbs. Zinc also reacts with halogens.

  6. Reaction of Zinc and Sulfur. Description: Insertion of red-hot wire into a small pile of powdered zinc and sulfur results in a large puff of yellowish smoke. This demonstration is also available on video and JCE “Chemistry Comes Alive!” vol. 3 CD-Rom. Source: Shakhashiri, B.Z. Chemical Demonstrations: A Handbook for Teachers of Chemistry.
