Only energy can move into or out of the system. d. Neither energy nor matter can move into or out of the system. e. None of the above. 2. Which of the following accurately describes the conditions of an isolated system? a. Both energy and matter can move into or out of the system. b. Only matter can move into or out of the system. c. Only energy can move into or out of the system. d. Neither energy nor matter can move into or out of the system. e. None of the above. 3. Which of the following reactions is/are endothermic? Choose ALL that apply. a. H2(g) + Cl(g) → 2HCI(g) + 185 kJ b. 302(g) + 286 kJ → 203(g) с. C(5) + O-(g) — СO,(9) d. N2(g) + 202(g) → 2NO2(g) e. 238U → 4He + 234TH + heat AHº = - 394 kJ AHº = +33.2 kJ f. H2O(s) + heat → → H,O(1I)
