container of water. The temperature of the lead drops to 60 °C. If the temperature of the water was originally at 30°C and ended at 60°C, calculate the mass of the water. Assume that all the heat lost by the lead was trapped by the water. I ( 25g) 5. 300 g of ice with a specific heat-capacity of 2.090 J/g°C is heated from -35 °C to -10 °C. Calculate the amount of heat(q) ( 1.6 x 10“ J) 6. A 2.50 g sample of sucrose (C12H22011) was burned in excess oxygen in a bomb calorimeter which contained 2.19 Kg of water. The temperature of the water increased from 20.50 °C to 25.01°C. Determine the molar heat of combustion for sucrose. (-5.67 x 10° KJ/mol 7. A 12.7 g sample of sulfur is placed in a bomb which is then filled with oxygen under pressure. The bomb is placed in the calorimeter which is filled with 2.20 Kg of water at 21.08 °C. The reaction mixture is ignited and the temperature rises to a high of 33.88 °C. From this data, calculate the molar heat of combustion of sulfur. (-2.38-10Tmol) 8. In a calorimetry experiment the burning of 5.08 g of benzene (C,H6) released enough heat to raise the temperature of 5.00 Kg of water from 10.1 °C to 19.6 °C. Determine the molar heat of combustion of benzene. (-3.06-l0T/ mol) 9. If 8.00 g of ammonium nitrate is dissolved in one litre of water for use as a plant fertilizer, amazon
