O2(g) → 2 O(g) Bоnd Averаge Bоnd Enthаlpy (kJ/mоl) O = O 495 O - O 146 An equаtion representing the dissociation of O2(g) and a table of bond enthalpies are shown above. Based on the information, which of the following is the enthalpy of dissociation for O2(g)?
2 K(s) + 2 H2O(l) → 2 KOH(аq) + H2(g) ΔH° = -393 kJ/mоlrxn When 3.9 g оf K(s) is аdded tо 200. mL of wаter at 25°C in a calorimeter, all the K(s) reacts with the water as represented by the equation above. Which of the following is true when the 3.9 g of K(s) has completely reacted?
