Question

Zn - ZnS - H2S - SO2 - SO3

Answer 1

Zn + S = ZnS

ZnS + 2HI = ZnI2 + H2S

2H2S + 3O2 = 2H2O + 2SO2

2SO2 + O2 = 2SO3

Answer 2

Chemical Reactions and Compounds

The chemical reactions and compounds mentioned in your question are as follows:

- Zn: This refers to the chemical symbol for zinc, which is a metallic element. - ZnS: This represents zinc sulfide, a compound formed by the combination of zinc and sulfur. - H2S: This stands for hydrogen sulfide, a colorless gas with a strong odor, commonly known as rotten egg gas. - SO2: This represents sulfur dioxide, a colorless gas with a pungent odor, formed by the combustion of sulfur or sulfur-containing compounds. - SO3: This refers to sulfur trioxide, a colorless liquid or white crystalline solid, formed by the reaction of sulfur dioxide with oxygen.

Chemical Equations and Reactions

Chemical equations can be used to represent the reactions involving these compounds. Here are a few examples:

1. Zn + H2S → ZnS + H2 - In this reaction, zinc reacts with hydrogen sulfide to form zinc sulfide and hydrogen gas.

2. SO2 + O2 → SO3 - This equation represents the reaction between sulfur dioxide and oxygen to produce sulfur trioxide.

3. H2S + I2 → S + 2HI - In this reaction, hydrogen sulfide reacts with iodine to form sulfur and hydrogen iodide.

4. SO2 + BaO → BaSO3 - This equation represents the reaction between sulfur dioxide and barium oxide to produce barium sulfite.

5. SO3 + Zn(OH)2 → ZnSO4 + H2O - In this reaction, sulfur trioxide reacts with zinc hydroxide to form zinc sulfate and water.

Please note that these are just a few examples, and there are many other possible reactions involving these compounds.
