Please answer all of the questions correctly
Hw M.dal1廾5 . A leaf in nature is an example of exquisite order. It forms spontaneously in nature because a) While order is created in the leaf, disorder is created in the surroundings because the exothermicity of the process. b) Order is created in the leaf but energy is absorbed also by it c A leaf is an example of a disoedered system. d) Nature ordained it to do so. 2· The entropy change is wrongly paired in one ofthe following: Br40 + Hag) â 2 HBr(g) Na(s)+1/2 Fg)NaF(s) C a) A b) B c) C d) D e) E 3- The entropy of the universe in a spontaneous process always a) Increases b) Decreases e) Stays the same d) Conclusions cannot be made 4 The Second Law statements: "heat cannot be turned completely to work and "the entropy always increases in the universe a) Cannot be easily reconciled b) Can be reconciled as follows: The part of the heat that is NOT converted to work i transferred to the surroundings increasing its entropy and thus of the universe as a whole c) Can be reconciled as follows: The heat gained by the surroundings results in a decrease of its entropy. d) The internal energy of the system is the key to reconciliation. 5. Consider the reaction:
