A pair of students in a coastal city in Italy are conducting an investigation in order to observe changes in thermal energy as they relate to states of matter. The students place an inflated balloon in a -4° Celsius freezer as part of their experimental procedure. Another pair of students in a coastal city in the United States conduct a very similar experiment, but use larger-sized balloons and a freezer that is set at 0° Fahrenheit. How are the results of the two investigations likely to compare?

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
