Chemistry-compounds-zinc and sulfur

Formation of zinc sulfide

Zinc reacts with sulfur according to the equation below.

8Zn_(s) + S_8(s) => 8ZnS_(s)

This should only be performed as a demonstration by trained teachers.
Weigh 10 grams of zinc powder.

Weigh 5 grams of sulfur

Mix the two powders evenly

Ignite the mixture with a bunsen burner or a gas bottle, as shown in the video.

The product of the reaction should be zinc sulfide but zinc oxide also forms.

VIew the video and suggest whether zinc oxide and zinc sulfide have a high melting temperature.

Is this reaction exothermic or endothermic? Explain.

Senior Chemistry.

5 grams of sulfur was added to 10 grams of zinc. Give the mol ratio in which the reactants were combined.

What is the oxidation state of zinc and sulfur before and after reaction?
