Reaction of methanol with dioxygen was carried out and `DeltaU` was found to be `-726"kJ mol"^(-1)` at 298 K. The enthalpy change for the reaction will be
`CH_(3)OH_((l))+(3)/(2)O_(2(g)) rarr CO_(2(g))+2H_(2)O_((l)) , DeltaH=-726"kJ mol"^(-1)`

The reaction of cyanamide (s), with dioxygen was carried out in a bomb calorimeter and DeltaU was found to be -742.7 kJ mol^(-1) at 298 K. Calculate the enthalpy change for the reaction at 298 K. NH_(2)CN_((g))+(3)/(2)O_(2)(g)toN_(2(g))+CO_(2(g))+H_(2)O_(l)

The reaction of cyanamide, NH_(2)CN(s) , with dioxygen was carried out in a bomb calorimeter, and DeltaU was found to be -742.7 kJ mol^(-1) at 298 K . Calculate enthalpy change for the reaction at 298 K . NH_(2)CN(g)+3/2O_(2)(g) rarr N_(2)(g)+CO_(2)(g)+H_(2)O(l)

The reaction of cyanamide, NH_(2)CN(s) , with dioxygen was carried out in a bomb calorimeter, and DeltaU was found to be -742.7 kJ mol^(-1) at 298 K . Calculate enthalpy change for the reaction at 298 K . NH_(2)CN(g)+3/2O_(2)(g) rarr N_(2)(g)+CO_(2)(g)+H_(2)O(l)

If DeltaH_(f)^(@) for H_(2)O_(2)(l) and H_(2)O(l) are -188kJ and mol^(-1) and -286 kJ mol^(-1) , what will be the enthalpy change of the reaction 2H_(2)O_(2)(l)to2H_(2)O(l)+O_(2)(g) ?
