The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

Here are the balanced chemical equations:<\/p>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n

    Balancing chemical equations ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the reaction.<\/p>\n\n\n\n

      \n
    1. First Reaction: Fe(NO\u2083)\u2083 + MgO<\/strong><\/li>\n<\/ol>\n\n\n\n
        \n
      • Iron(III) nitrate reacts with magnesium oxide to form iron(III) oxide and magnesium nitrate.<\/li>\n\n\n\n
      • Each side must have the same number of Fe, NO\u2083, Mg, and O atoms.<\/li>\n\n\n\n
      • Balancing Fe, NO\u2083, and Mg requires a 2:3:1:3 ratio.<\/li>\n<\/ul>\n\n\n\n
          \n
        1. Second Reaction: (NH\u2084)\u2083N + Cr(CrO\u2084)\u2082<\/strong><\/li>\n<\/ol>\n\n\n\n
            \n
          • The ammonium nitride reacts with chromium chromate to form ammonium chromate and chromium nitride.<\/li>\n\n\n\n
          • The coefficient 2 before Cr(CrO\u2084)\u2082 ensures equal Cr atoms on both sides.<\/li>\n\n\n\n
          • The nitrogen atoms must also balance.<\/li>\n<\/ul>\n\n\n\n
              \n
            1. Third Reaction: Cu\u2083(PO\u2084)\u2082 + Na\u2082SO\u2084<\/strong><\/li>\n<\/ol>\n\n\n\n
                \n
              • Copper(II) phosphate reacts with sodium sulfate to form sodium phosphate and copper sulfate.<\/li>\n\n\n\n
              • Sodium and phosphate ions are balanced with a 3:2 ratio.<\/li>\n<\/ul>\n\n\n\n
                  \n
                1. Fourth Reaction: AlCl\u2083 + H\u2082O<\/strong><\/li>\n<\/ol>\n\n\n\n
                    \n
                  • Aluminum chloride reacts with water to form aluminum hydroxide and hydrochloric acid.<\/li>\n\n\n\n
                  • The reaction follows a 1:3:1:3 ratio to balance the Cl and OH groups.<\/li>\n<\/ul>\n\n\n\n

                    These steps ensure mass balance and charge neutrality, making the equations chemically correct.<\/p>\n","protected":false},"excerpt":{"rendered":"
