The equation is:
3 O₂ + 4 Co → 2 Co₂O₃
Oxidation half reaction:
Co → Co³⁺ + 3 e
Reduction half reaction:
O₂ + 4 e → 2 O²⁻
To balance the equation number of electrons lost must be equal to number or electrons gained so we must multiply oxidation half time 4 and reduction half times 3
Tbh I would pick A because the liquid* decreases. B doesn’t increase
Answer:
The student is Incorrect
Explanation:
Even if you break a magnet the poles still remains same. There is no
difference in the magnet Both north and south pole will be there even if you
cut it in to small pieces when you cut it into pieces, if suppose you break 2
magnets and put north and north together it will repel whereas if there are
different poles like north and south it will attract, so even if you break one
single magnet the different poles will attract, Hence the student is incorrect.
