Answer 1

To determine if any of the provided equations are balanced, we need to check the number of atoms of each element on both sides of the equation.

1. C8H8 + 4O2 → 3CO2 + 3H2O

   • Left side: C = 8, H = 8, O = 8
   • Right side: C = 3 (from CO2), H = 6 (from H2O), O = 6 (from CO2) + 3 (from H2O) = 9
   • Not balanced.

2. C8H8 + 3O2 → 3CO2 + 4H2O

   • Left side: C = 8, H = 8, O = 6
   • Right side: C = 3 (from CO2), H = 8 (from H2O), O = 6 (from CO2) + 4 (from H2O) = 10
   • Not balanced.

3. C8H8 + 5O2 → 3CO2 + 4H2O

   • Left side: C = 8, H = 8, O = 10
   • Right side: C = 3 (from CO2), H = 8 (from H2O), O = 6 (from CO2) + 4 (from H2O) = 10
   • Not balanced.

4. C8H8 + 2O2 → CO2 + 4H2O

   • Left side: C = 8, H = 8, O = 4
   • Right side: C = 1 (from CO2), H = 8 (from H2O), O = 2 (from CO2) + 4 (from H2O) = 6
   • Not balanced.

None of the given equations are balanced.

Answer 2

whats the best one

Answer 3

To identify the "best" equation among the given options, we should look for the one that comes closest to being balanced. None of them are perfectly balanced, but we can analyze each for its degree of imbalance.

1. C8H8 + 4O2 → 3CO2 + 3H2O

   • Atoms:
     • C: 8 on the left, 3 on the right
     • H: 8 on the left, 6 on the right
     • O: 8 on the left, 9 on the right

2. C8H8 + 3O2 → 3CO2 + 4H2O

   • Atoms:
     • C: 8 on the left, 3 on the right
     • H: 8 on the left, 8 on the right
     • O: 6 on the left, 10 on the right

3. C8H8 + 5O2 → 3CO2 + 4H2O

   • Atoms:
     • C: 8 on the left, 3 on the right
     • H: 8 on the left, 8 on the right
     • O: 10 on the left, 10 on the right

4. C8H8 + 2O2 → CO2 + 4H2O

   • Atoms:
     • C: 8 on the left, 1 on the right
     • H: 8 on the left, 8 on the right
     • O: 4 on the left, 6 on the right

Based on this evaluation, the third option C8H8 + 5O2 → 3CO2 + 4H2O is the best one, as it has the same number of hydrogen atoms on both sides and has the same number of oxygen atoms on both sides (10). However, it still has an imbalance in carbon atoms (8 on the left vs. 3 on the right).

Even though none of the equations are completely balanced, the third one maintains the closest equality in terms of the total count of atoms for some elements (specifically hydrogen and oxygen), despite the carbon being unbalanced.
