[" For the reactions,"],[2C+O_(2)rarr2CO_(2);quad Delta H=-393I]

For the reaction, C+O_(2) rarr CO_(2), DeltaH=-393J 2Zn+O_(2) rarr 2ZnO,DeltaH=-412J Which one is correct ?

For the reaction, C+O_(2)rarrCO_(2) , DeltaH=-393 J 2Zn+O_(2) rarr 2ZnO , DeltaH=-412J

For the reaction, C+O_(2) rarr CO_(2),DeltaH=-393 J 2Zn + O_(2) rarr 2ZnO, H=-412 J

For the reaction, C+O_(2) rarr CO_(2),DeltaH=-393 J 2Zn + O_(2) rarr 2ZnO, DeltaH=-412 J

In a reaction, H_(2)O +C rarr CO +H_(2)

From the thermochemical reactions, C(grap hite)+1//2O_(2)rarr CO , Delta H =-110.5 KJ CO+1//2O_(2)rarr CO_(2),Delta H=-283.2 KJ The heat of reaction of C(graph ite) +O_(2)rarr CO_(2) is :

From the thermochemical reactions, C(graphite) +1//2O_(2)rarr CO , Delta H = -110.5 KJ CO+1//2O_(2)rarr CO_(2),Delta H=-283.2 KJ the heat of reaction of C(graphite) +O_(2)rarr CO_(2) is :
