Question: Predict whether the entropy change is positive or negative for each of these reactions: (a) Zn(s) + 2HCl(aq) ZnCl2(aq) + H2(g) (b) O(g) +

Predict whether the entropy change is positive or negative for each of these reactions:
(a) Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
(b) O(g) + O(g) → O2(g)
(c) NH4NO3(s) → N2O(g) + 2H2O(g)
(d) 2H2O2(l) → 2H2O(l) + O2(g)
