Dwayne filled a small balloon with air at 298.5 k. he put the balloon into a bucket of water, and the water level in the bucket increased by 0.54 liter. if dwayne puts the balloon into a bucket of ice water at 273.15 k and waits for the air inside the balloon come to the same temperature, what will the volume of the balloon be? assume the pressure inside the balloon doesn’t change. type the correct answer in the box. express your answer to the correct number of significant figures. the volume of the balloon at 273.15 k is liters.

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.
