A bomb calorimeter is used to determine thermal properties. Calculate the molar enthalpy of the combustion of glucose when 2.22 g of glucose are ignited and water (1.2 kg) in the well-insulated calorimeter rises in temperature from 18℃ to 23.19℃. Assume that the water absorbs all heat given off.

When a solid dissolves in water, the solution may become hotter or colder. The dissolution enthalpy (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 14.44 g Cs,SO4(s) is dissolved in 119.20 g water, the temperature of the solution drops from 24.80 to 23.20 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.85 J/°C. Based on the student's observation, calculate the dissolution enthalpy of CS2SO4(s) in kJ/mol. Assume the specific heat capacity of the solution is equal to the specific heat capacity of water. AdisH = kJ/mol

When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 14.11 g of CsCl(s) are dissolved in 119.20 g of water, the temperature of the solution drops from 25.67 to 22.23 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.55 J/ °C. Based on the student's observation, calculate the enthalpy of dissolution of CSCI(s) in kJ/mol. Assume the specific heat of the solution is equal to the specific heat of water. AH dissolution= kJ/mol

A 6.40 g sample of butane, C4H10(g), was burned in a bomb calorimeter in the presence of excess oxygen. The calorimeter contained 4.86 kg of water. Calculate the heat exchanged with respect to the system during the reaction if the calorimeter has a heat capacity of 254. J/°C and the temperature of the calorimeter and water changed from 29.0°C to 43.2°C? Enter your answer to 3 significant figures in decimal form. Do not enter units since they are already given. kJ Calculate the heat exchanged with respect to the system per mole of butane. Enter your answer to 3 significant figures in decimal form. Do not enter units since they are already given. kJ Compared with the previous problem, is the energy released pretty much the same or different? Enter "same" or "different" Compared with the previous problem, is the energy released per mole pretty much the same or different? Enter "same" or "different"
