II. Heat Capacity and Calorimetry 5. In a styrofoam (coffee) - cup calorimeter, 100.0 mL of 1.01 M NaOH and 100.0 mL of 1.0 M HCI are mixed. Both solutions were originally at 23.8°C, After the reaction, the final temperature is 30.5â. Assuming that all the solutions have a density of 1.0 gem3 and a specific heat capacity of 4.18 J/gâ, calculate the enthalpy change for the neutralization of HCl by NaOH. [Assume that no heat is lost to the surroundings or to the calorimeter. 6. A lead bullet with a mass of 8.00 g and traveling at 5.00 x 10* cm/s is imbedded in a wooden block weighing 1,000 kg. If both the block and the bullet were initially at 25.0°C, what is the final temperature of the block containing the bullet? The specific heat of wood is 0.50 cal/g·â; that of lead is 0.030 cal/g. °C. l cal-41 841, and J = kg·m2/s. { Assume no heat loss to the surroundings You may also assume that the heat absorbed by the bullet is negligible! Why?)
