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. Pick one of the above reactions and calculate how much 1.0 g of the solid would increase the temperature of 100 mL of water. Let your...

Determine whether each reaction is endothermic or exothermic, and spontaneous or nonspontaneous.
Calculate \(\Delta \mathrm{H}^{\circ}\) and \(\Delta \mathrm{G}^{\circ}\), using data in Appendix C. Determine whether each reaction is endothermic or exothermic, and spontaneous or nonspontaneous.a) \(\quad 2 P b O(s)+N_{2}(g) \rightarrow 2 P b(s)+2 N O(g)\)b) \(\mathrm{CS}_{2}(l)+2 \mathrm{H}_{2} \mathrm{O}(l) \rightarrow \mathrm{CO}_{2}(g)+2 \mathrm{H}_{2} \mathrm{~S}(g)\)
