A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.4987 g sample of 2-naphthylacetic acid (C12H1002) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.203x103 g of water. During the combustion the temperature increases from 23.43 to 25.91 °C. The heat capacity of water is 4.184 J g-loc-1. The heat capacity of the calorimeter was determined in a previous experiment to be 896.5 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of 2-naphthylacetic acid based on these data.

A certain chemical reaction releases 269. kJ of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put into a calorimeter (a device for measuring heat flow). It takes 3.21 J of heat energy to raise the temperature of this calorimeter by 1 °C. Now the reaction is run until all the reactant is gone, and the temperature of the calorimeter is found to rise by 5.0 °C. How would you calculate the number of moles of reactant that were consumed? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. moles consumed = x10 010 X Ś
