What is the minimum number of moles of potassium permanganate that would be required to completely oxidize 1.0 moles of benzaldehyde?

Mole ratio :

5 C₆H₆CHO + 2 KMnO₄ + 6 H⁺ = 5 C₆H₆COOH + 2 Mn²⁺ + 3 H₂O + 2 K⁺

5 moles C₆H₆CHO 2 moles KMnO₄
1.0 moles C₆H₆CHO ( moles of KMnO₄ )

moles of KMnO₄ = 1.0 x 2 / 5

moles of KMnO₄ = 2 / 5

= 0.40 moles of KMnO4

hope this helps!

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
