Can someone please explain how to see how entropy is negative, positive, or zero, thanks!
Read Answer Items for Question 8 Answer A. negative B. positive C. essentially zero D. negative E. positive








Predict, using the intuitive ideas about entropy, whether Ssys will be positive, negative, or essentially zero for each of the following: Ca(OH)2(s) + CO2(g) CaCO3(s) + H2O(g) CuSO4(s) Cu2+(aq) + SO42-(aq) 2HCl(g) + Br2(l) 2HBr(g) + Cl2(g) SO2(g) + 1/2 O2(g) SO3(g) Cu2+(aq) + 4NH3(aq) Cu(NH3)42+(aq) negative positive essentially zero negative positive
