Question

For the reactions \(C + O2 \rightarrow CO2\); \(\, \Delta H = -393 \, \text{kJ} 2Zn + O2 \rightarrow 2ZnO\), \(\, \Delta H = -412 \, \text{kJ}\) \(\text{the correct statement is:}\)

• A. carbon can oxidize Zinc
• B. oxidation of carbon does not take place
• C. zinc oxidation is not possible
• D. Zinc can oxidize carbon

Hint:

Remember that oxidation involves the loss of electrons. In this case, carbon provides electrons to zinc, causing zinc to be oxidized.

Answer 1

The Correct Option is A

In the given reactions, carbon is shown to oxidize zinc in the second reaction.
This is evident as zinc is oxidized, which requires the presence of carbon.
Hence, carbon can oxidize zinc.
