Reaction enthalpy or reaction trope (thermo-11)

For each of the following procedures, consider whether there is an increase or decrease in entropy and the enthalpy of the chemical system is expected (e.g. ΔHoR Other:

1. CO₂(s) Sublimated to CO₂(g)
2. Heating of CaCO₃(s)
3. CO₂(g) + CaO(s) → CaCO₃(s)
4. H₂O(s) → H₂O(l) → H₂O(g) → 0.5·O₂(g) + H₂(g)
5. Ba(OH)₂(s) + 2·NH₄SCN(s) → Ba(SCN)₂ + 2·NH₃(g) + 2·H₂O(l)
6. NH₃(g) + HCl(g) → NH₄Cl(s)
