The given chemical equation represents the conversion of zinc (Zn) to sodium sulfate (Na2SO4) through a series of intermediate compounds. Here's a breakdown of the steps involved:<br /><br />1. **Zinc (Zn)**: The starting material is zinc, a metal.<br /><br />2. **Zinc Sulfide (ZnS)**: Zinc reacts with sulfur to form zinc sulfide.<br /><br />3. **Hydrogen Sulfide (H2S)**: Zinc sulfide reacts with hydrogen to produce hydrogen sulfide gas.<br /><br />4. **Sulfur (S)**: Hydrogen sulfide decomposes to give elemental sulfur.<br /><br />5. **Sulfur Dioxide (SO2)**: Sulfur reacts with oxygen to form sulfur dioxide.<br /><br />6. **Sulfur Trioxide (SO3)**: Sulfur dioxide further reacts with oxygen to produce sulfur trioxide.<br /><br />7. **Sulfuric Acid (H2SO4)**: Sulfur trioxide reacts with water to form sulfuric acid.<br /><br />8. **Sodium Sulfate (Na2SO4)**: Sulfuric acid reacts with sodium hydroxide to produce sodium sulfate.<br /><br />So, the overall reaction can be summarized as:<br />\[ Zn \rightarrow ZnS \rightarrow H_2S \rightarrow S \rightarrow SO_2 \rightarrow SO_3 \rightarrow H_2SO_4 \rightarrow Na_2SO_4 \]<br /><br />This sequence of reactions shows the transformation of zinc into sodium sulfate through a series of chemical transformations.
