In an experiment to determine the caloric content of a granola bar, a 0.5 g sample of the bar was burned in an oxygen atmosphere and the temperature rose by 11.12 oC. In a separate experiment using the same calorimeter, a 1.27 A current from a 12.5 V source was applied for 180 s and the temperature rose 3.88 oC. (a) Calculate the heat capacity of the calorimeter. (The heat produced by electric elements is as follows: q = IVt) (b) Calculate the heat released (in Joules) by the sample. (c) Calculate the bar’s caloric content. (1 dietary calorie = 4.184 kJ; mbar = 23 g)

In an experiment to determine the caloric value of food, a sample of food was burned in an oxygen atmosphere and the temperature rose by 2.89°C. When a current of 1.27 A from a 15v source flowed through the same calorimeter for 160 seconds, the temperature rose by 4 °C. What is the heat released by the combustion?
A 1.20-g sample of maleic acid (C4H4O4) is burned in a bomb calorimeter and the temperature increases from 24.70 °C to 27.41 °C. The calorimeter contains 1000 g of water and the bomb has a heat capacity of 839 J/°C. The heat capacity of water is 4.184 J g-1°C-1. Based on this experiment, calculate ΔE for the combustion reaction per mole of maleic acid burned.

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 0.3568 g sample of bianthracene (C28H18) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.030x10 g of water. During the combustion the temperature increases from 25.45 to 28.29 °C. The heat capacity of water is 4.184 J gC The heat capacity of the...
a. A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.532-g sample of nonanedioic acid (C9H16O4) in a bomb calorimeter containing 1050. g of water. The temperature increases from...
