Rewrite the original reaction to show one mole of each of thefollowing reacting. Use the appropriate molar enthalpy from question $2$ within each equation.

a$)$ Bi:

b$)$ O$2$:

c$)$ Bi$2$O$5$ :

Original equation is $4$Bi$($s$)+5$O$2($g$)->2$Bi$2$O$5($s$)$

The heat release is $3360$ kJ

The enthalpys from question $2$ are AHBi $=-840$ kJ$/$ mol,

AHO$2=-672$ kJ$/$mol and

AHBiO$5=-1680$ kJ$/$ mol
