Chemistry Balancing Act POGIL Worksheet Model 3 – I don’t get it<\/p>\n\n\n\n

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

In the Chemistry Balancing Act POGIL Worksheet Model 3<\/strong>, the main goal is to understand how to balance chemical equations based on the Law of Conservation of Mass<\/strong>. This law states that matter cannot be created or destroyed<\/strong> in a chemical reaction. Therefore, the number of atoms of each element must be the same on both sides of the equation.<\/p>\n\n\n\n

Model 3 typically presents a more complex unbalanced chemical equation compared to earlier models. An example may be:<\/p>\n\n\n\n

C\u2083H\u2088 + O\u2082 \u2192 CO\u2082 + H\u2082O<\/strong><\/p>\n\n\n\n

To balance this equation:<\/p>\n\n\n\n

    \n
  1. Count atoms of each element on both sides<\/strong>:\n
      \n
    • On the left: C = 3, H = 8, O = 2<\/li>\n\n\n\n
    • On the right: C = 1 (in CO\u2082), H = 2 (in H\u2082O), O = 3 (2 in CO\u2082 and 1 in H\u2082O)<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Balance carbon atoms<\/strong>:\n
        \n
      • Place a coefficient 3 in front of CO\u2082:
        C\u2083H\u2088 + O\u2082 \u2192 3CO\u2082 + H\u2082O<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Balance hydrogen atoms<\/strong>:\n
          \n
        • Place a coefficient 4 in front of H\u2082O:
          C\u2083H\u2088 + O\u2082 \u2192 3CO\u2082 + 4H\u2082O<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Balance oxygen atoms<\/strong>:\n
            \n
          • Right side has 3\u00d72 = 6 (from CO\u2082) + 4\u00d71 = 4 (from H\u2082O) = 10 O atoms<\/li>\n\n\n\n
          • Left side O\u2082 means 2 oxygen atoms per molecule<\/li>\n\n\n\n
          • 10 \u00f7 2 = 5, so place a 5 in front of O\u2082:
            C\u2083H\u2088 + 5O\u2082 \u2192 3CO\u2082 + 4H\u2082O<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

            Now the equation is balanced:<\/p>\n\n\n\n

              \n
            • Carbon: 3 atoms on both sides<\/li>\n\n\n\n
            • Hydrogen: 8 atoms on both sides<\/li>\n\n\n\n
            • Oxygen: 10 atoms on both sides<\/li>\n<\/ul>\n\n\n\n

              Balancing equations ensures accuracy in chemical predictions and reflects real-world chemical behavior. Coefficients in front of compounds change the quantity of molecules, not the identity of the compounds. Subscripts inside formulas must remain unchanged, as they represent the actual structure of the molecules.<\/p>\n\n\n\n
