Please help me with number 2 only and send paper solutions
of 4 Calorimetry Problems 1. In an experiment, paradichlorobenzene was heated from 25°C to 52"C. If 200 g of paradichlorobenzene is heated and the specific heat capacity for this substance is 0.920 J/g"C calculate the quantity of heat added. (5000 J) 2. An aluminum container with specific heat capacity of 0.880 J/g°C contains waxwith specific heat capacity 2.880 J/g°C. The mass of the aluminum container and wax is 160 g while the mass of the container alone is 110 g. How much heat must be added to increase the temperature of the container and wax by 25°C. ( 6020 J) 3. A candle, as it burns, releases 8.80 x 10* J of heat which is trapped by a 100 Kg piece of aluminum. Calculate the change in temperature of the aluminum. The specific heat capacity of aluminum is 0.880 J/g°C. (1.0 °C) 4. A piece of lead having a mass of 500 g and a temperature of 100 °C is dropped into a 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. ( 1.6 x 10 J) int of heatla).
