Consider the reaction 2 N20 (g) – 2N, (g) + 02 (g). Calculate the work in kJ units at T= 320.0 K (in kJ and in 4 Significant Figures with a positive or negative sign). (Gas constant = 8.3145 J/mol K). No need to write kJ. Answer would be something like +3440 or -3442 or +23.21 or -23.21
You weighed your empty insulated cup and found that the mass of the cup was 3.6 g. You add some hot water and find that the total mass increases to 26.3 g. You got some ice from the bus tub, and found that it was wet. After drying it carefully, you take the temperature of the hot water in the cup and find that its temperature is 55.9 °C and then add the ice. The temperature of the water dropped, and came to equilibrium at 35.2 °C. At the end of the experiment you re-weigh the cup and find that the mass has increased to 31.7 g. What is your experimental value for the heat of fusion?
