Write the balanced equation for the reaction involved in the synthesis of acetanilide from aniline and acetic anhydride.
A 3.9-g sample of Colorado oil shale is burned in a bomb calorimeter, which causes the temperature of the calorimeter to increase by 5.0°C. The calorimeter contains 1.00 kg of water (heat capacity of H2O = 4.184 J/g°C) and the heat capacity of the..
