Document Summary
179 j of work is done by the system to the surroundings. 6 c graphite + h g + o g + n g. The specified reaction is twice the reverse of the formation reaction, and its enthalpy change is minus two times the enthalpy of formation of nh g3b g : b. Exercises: the contents of the vessel after completion of the reaction are 74. 1 g of ca(oh)2 and 66. 3 g. The t here is known to just one significant figure (0. 9 c). Doubling the amount of koh should give a temperature change known to two significant figures (1. 6 c) and using twenty times the mass of koh should give a temperature change known to three significant figures (16. 0 c). 2: 39. 6 g, 1. 83 g h2o, 0. 111 l, 4. 98 kj / co. +18 kj/mol: 7. 72kj/ c , 5. 23 c , 15 g.
