Unformatted text preview: heat. As the gas is warmed the piston volume increases by 3.17 L against a pressure of 1.07 atm. What is the change in the internal energy of the gas in the piston? 3. (4 pts) Diborane (B 2 H 6 ) is produced through the reaction here: 2B(s) + 3H 2 (g) B 2 H 6 (g) Determine the H for the synthesis of one mole of diborane given the following data: (a) 2B(s) + 3/2 O 2 (g) B 2 O 3 (s) H = -1273 kJ (b) B 2 H 6 (g) + 3O 2 (g) B 2 O 3 (s) + 3H 2 O(g) H = -2035 kJ (c) H 2 (g) + 1/2 O 2 (g) H 2 O( l ) H = -286 kJ (d) H 2 O( l ) H 2 O(g) H = 44 kJ...
