The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
Yes, this is correct. The reaction you’ve provided is a single displacement reaction, as zinc displaces hydrogen from sulfuric acid, and it is also a redox (reduction-oxidation) reaction.<\/p>\n\n\n\n
1. Single Displacement Reaction:<\/strong><\/h3>\n\n\n\n
In a single displacement reaction, one element replaces another in a compound. In this case, zinc (Zn) replaces hydrogen (H) in sulfuric acid (H2SO4), resulting in the formation of zinc sulfate (ZnSO4) and hydrogen gas (H2). The general form of a single displacement reaction is:<\/p>\n\n\n\n
A+BC\u2192AC+BA + BC \\to AC + BA+BC\u2192AC+B<\/p>\n\n\n\n
Here, zinc (Zn) replaces hydrogen (H) from sulfuric acid (H2SO4), producing zinc sulfate (ZnSO4) and hydrogen gas (H2).<\/p>\n\n\n\n
2. Redox Reaction:<\/strong><\/h3>\n\n\n\n
This is also a redox reaction because both oxidation and reduction occur simultaneously.<\/p>\n\n\n\n
\n
Oxidation (Loss of Electrons):<\/strong> Zinc (Zn) undergoes oxidation. Zinc metal loses two electrons to form zinc ions (Zn\u00b2\u207a). This is the oxidation half-reaction:<\/li>\n<\/ul>\n\n\n\n
Reduction (Gain of Electrons):<\/strong> The hydrogen ions (H\u207a) from sulfuric acid are reduced. These hydrogen ions gain electrons to form hydrogen gas (H2). This is the reduction half-reaction:<\/li>\n<\/ul>\n\n\n\n
Thus, zinc (Zn) is oxidized (loses electrons) and hydrogen ions (H\u207a) are reduced (gain electrons).<\/p>\n\n\n\n
3. Balanced Equation:<\/strong><\/h3>\n\n\n\n
The overall balanced equation, taking both half-reactions into account, is:Zn(s)+H2SO4(aq)\u2192ZnSO4(aq)+H2(g)\\text{Zn}(s) + \\text{H}_2\\text{SO}_4(aq) \\to \\text{ZnSO}_4(aq) + \\text{H}_2(g)Zn(s)+H2\u200bSO4\u200b(aq)\u2192ZnSO4\u200b(aq)+H2\u200b(g)<\/p>\n\n\n\n
Conclusion:<\/h3>\n\n\n\n
The reaction is both a single displacement<\/strong> reaction (since zinc displaces hydrogen) and a redox<\/strong> reaction (since oxidation and reduction occur). Therefore, the classification you provided is accurate.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
