Answer 7-9 please thanks
7-8. Predict whether the entropy change is positive or negative for each of the following PCI5(s) reactions: PCl3() + Cl2(g) 2H9O(s)- 2Hg()+O2(g) > 9. How are system changes treated in the study of thermodynamics? A. Change (A) = (initial - final) B. Change (A) = (initial + final) 10. Which of the following follows the correct writing of thermochemical C. Change (A) = (final - initial) D. Change (A) = (final + initial) %3D equations?
