Reaction Analysis for Given Reactant Pairs<\/strong><\/h3>\n\n\n\n

To determine whether a reaction will occur, we need to analyze the activity series of metals. A metal will replace another metal in a compound only if it is more reactive (i.e., higher in the activity series). The activity series ranks metals from most reactive to least reactive. Here\u2019s the assessment:<\/p>\n\n\n\n

1. Al(s) + Ba(NO\u2083)\u2082(aq) \u2192 No Reaction<\/strong><\/h4>\n\n\n\n
    \n
  • Explanation:<\/strong> Aluminum (Al) is lower than Barium (Ba) in the activity series, meaning Al is less reactive<\/strong> than Ba. Since Al cannot replace Ba in Ba(NO\u2083)\u2082<\/strong>, no reaction occurs<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    2. Cr(s) + Co(NO\u2083)\u2082(aq) \u2192 Reaction Occurs<\/strong><\/h4>\n\n\n\n
      \n
    • Explanation:<\/strong> Chromium (Cr) is higher<\/strong> than Cobalt (Co) in the activity series. This means Cr is more reactive and can displace<\/strong> Co from Co(NO\u2083)\u2082<\/strong>, forming Cr(NO\u2083)\u2083 and solid Co.<\/li>\n\n\n\n
    • Balanced Reaction:<\/strong>
      [
      2Cr(s) + 3Co(NO\u2083)\u2082(aq) \u2192 2Cr(NO\u2083)\u2083(aq) + 3Co(s)
      ]<\/li>\n<\/ul>\n\n\n\n

      3. Zn(s) + HCl(aq) \u2192 Reaction Occurs<\/strong><\/h4>\n\n\n\n
        \n
      • Explanation:<\/strong> Zinc (Zn) is more reactive than Hydrogen (H\u2082). Zn will react with hydrochloric acid (HCl), replacing hydrogen and forming ZnCl\u2082<\/strong> and H\u2082 gas<\/strong>.<\/li>\n\n\n\n
      • Balanced Reaction:<\/strong>
        [
        Zn(s) + 2HCl(aq) \u2192 ZnCl\u2082(aq) + H\u2082(g)
        ]<\/li>\n<\/ul>\n\n\n\n

        4. Zn(s) + CuSO\u2084(aq) \u2192 Reaction Occurs<\/strong><\/h4>\n\n\n\n
          \n
        • Explanation:<\/strong> Zinc (Zn) is more reactive than Copper (Cu) and will replace Cu from CuSO\u2084, forming ZnSO\u2084<\/strong> and solid Cu<\/strong>.<\/li>\n\n\n\n
        • Balanced Reaction:<\/strong>
          [
          Zn(s) + CuSO\u2084(aq) \u2192 ZnSO\u2084(aq) + Cu(s)
          ]<\/li>\n<\/ul>\n\n\n\n

          Conclusion<\/strong><\/h3>\n\n\n\n
            \n
          • No reaction:<\/strong> Al(s) + Ba(NO\u2083)\u2082(aq)<\/li>\n\n\n\n
          • Reaction occurs:<\/strong> Cr(s) + Co(NO\u2083)\u2082(aq)<\/li>\n\n\n\n
          • Reaction occurs:<\/strong> Zn(s) + HCl(aq)<\/li>\n\n\n\n
          • Reaction occurs:<\/strong> Zn(s) + CuSO\u2084(aq)<\/li>\n<\/ul>\n\n\n\n

            Now, I will generate an image representing these reactions.<\/p>\n\n\n\n

            The image visually represents the chemical reactions, showing which ones occur and which do not. Let me know if you need any modifications or further explanations!<\/p>\n\n\n\n
