For the following process, determine the change in entropy for the system (δssys), the surrounding (δssys), and the universe (δsuniv). then identify the process as a spontaneous process, a nonspontaneous process, or an equilibrium process at the specified temperature. (assume that the thermodynamic data will not vary with temperature.) pcl3(l) → pcl3(g) at 61.2°c δh o f ( kj mol ) −319.7 −288.07 s o ( j k · mol ) 217.1 311.7 δssys = j k · mol δssurr = j k · mol δsuniv = j k · mol

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
