Let's analyze each equation for balancing:
-
\( C_5H_5 + O_2 \to 3CO_2 + 3H_2O \)
- Reactants: \( 5 \) carbons, \( 5 \) hydrogens, and some number of oxygens.
- Products: \( 3 \) CO₂ contributes \( 3 \times 2 = 6 \) oxygens and \( 3 \) H₂O contributes \( 3 \) oxygens, total \( 6 + 3 = 9 \) oxygens.
- This is not balanced.
-
\( C_5H_5 + O_2 \to 8CO_2 + 4H_2O \)
- Reactants: \( 5 \) carbons, \( 5 \) hydrogens.
- Products: \( 8 \) CO₂ contributes \( 8 \times 2 = 16 \) oxygens and \( 4 \) H₂O contributes \( 4 \) oxygens, total \( 16 + 4 = 20 \) oxygens.
- This is not balanced.
-
\( C_5H_5 + 2O_2 \to CO_2 + 4H_2O \)
- Reactants: \( 5 \) carbons, \( 5 \) hydrogens.
- Products: \( 1 \) CO₂ contributes \( 2 \) oxygens and \( 4 \) H₂O contributes \( 4 \) oxygens, total \( 2 + 4 = 6 \) oxygens.
- This is not balanced.
-
\( CH + 5O_2 \to 3CO_2 + 4H_2O \)
- Reactants: \( 1 \) carbon and \( 1 \) hydrogen with \( 5 \) Oxygens.
- Products: \( 3 \) CO₂ contributes \( 6 \) oxygens and \( 4 \) H₂O contributes \( 4 \) oxygens, total \( 6 + 4 = 10 \) oxygens.
- This is also not balanced.
None of the provided equations are correctly balanced.
