4. Hot packs. All reactions are spontaneous; note that some are exothermic and some are endothermic. How can a spontaneous reaction Increase in energy? Hot packs, exothermic: CaClas) → Calag) + 2CH(aq) 4,H=-81.35 kd/mol. MgSO4(s) → Mg?"(aq) +507(ag) AH-91.22 kJ/mol Just plain hot-watch out! NaOH(s) → Na'(aq) + OH'(aq) AH = -44.50 kJ/mol. a.
