2 Answers. Sorted by: 6. 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).
Chemistry questions and answers; chemical reaction between zinc and sulfur. 1.Write the chemical reaction with all the symbols possible and balance the reaction. 2.if 1.2 g of zinc powder and 1.2 grams of sulfur poeder was used, Do you have equal amounts of each atom? 3. which one would be left over (have more)(show math)
Just like iron, zinc (Zn) reacts with sulfur. The reaction produces zinc sulfide, ZnS. By the way, ZnS is an important compound that has a broad variety of applications in materials for electronics and optical devices, as a pigment, and also as a catalyst .
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.
15 sty 2019 · Recognize a reaction as an oxidation-reduction reaction. In the course of a chemical reaction between a metal and a nonmetal, electrons are transferred from the metal atoms to the nonmetal atoms. For example, when zinc metal is mixed with sulfur and heated, the compound zinc sulfide is produced.
The reaction between zinc powder and sulfur. A reaction between zinc and sulfur can be used to demonstrate that chemical changes are often accompanied by a large change in energy. Introduction.
