The heat capacity of a bomb calorimeter is found to be 5.68 kJ/oC. When a 1.652 g sample of glucose is burned in the calorimeter, the temperature of the calorimeter increases from 24.56 oC to 29.10 oC. Calculate the heat of combustion of glucose.
Write the net ionic equation for this reaction. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.)
