Recall that **ΔH˚ _{rxn}** can be calculated from the

$\overline{){\mathbf{\u2206}}{{\mathbf{H}}}_{{\mathbf{rxn}}}^{{\mathbf{\xb0}}}{\mathbf{=}}{\mathbf{\u2206}}{{\mathbf{H}}}_{\mathbf{f}\mathbf{,}\mathbf{products}}^{{\mathbf{\xb0}}}{\mathbf{-}}{\mathbf{\u2206}}{{\mathbf{H}}}_{\mathbf{f}\mathbf{,}\mathbf{reactants}}^{{\mathbf{\xb0}}}}$

Find ΔH for MgCO_{3} from the given table.

**Express your answer using one decimal place.**
