1.

For the reaction, `C+O_(2)rarrCO_(2)`, `DeltaH=-393 J` `2Zn+O_(2) rarr 2ZnO`, `DeltaH=-412J`A. carbon can oxidise zincB. oxidation of carbon is not possibleC. oxidation of zinc is not fessibleD. zinc can oxidise carbon.

Answer» Correct Answer - A
Zinc can lose electrons (O.S. of Zn chagnes from 0 to+2) and carbon can gain electrons (O.S. of C change from 0 to-4). Hence zinc is oxidised by carbon .
