Question

Which reaction involves a redox process where the reducing agent loses electrons without gaining oxygen?

Choose one · Correct answer highlighted

2Co + Br₂ → 2CoBr Correct 2Mg + O₂ → 2MgO C + O₂ → CO₂ 2CuO + CO → 2Cu + CO₂

In 2Co + Br₂ → 2CoBr, Co (0 to +1) loses electrons to reduce Br (0 to -1), with no oxygen involved.
