Enthalpy of formation of ${\mathrm{H}}_2\mathrm{O}(\ell ),{\mathrm{CO}}_2(\mathrm{g})$ and ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6(\mathrm{s})$ at standard state is $\mathrm{x},\mathrm{y}$ and z $\mathrm{kJ}/\mathrm{mol}$. The heat of combustion of ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6(\mathrm{s})$ at standard state (in $\mathrm{kJ}/\mathrm{mol}$ ) is
