Tribitroglycerin (C3H5N3O9) (usually referred to as nitroglycerin or TnT) has been widely used as an explosive. Alfed Nobel used it to make dynamite in 1866. It also has medical application and is used to relieved chest pain from partially blocked arteries. At 1 atm pressure and temperature 25C the enthalpy of this compound to form nitrogen gas (N2) Carbon dioxide gas (CO2), liquid water and oxygen (O2) is -1541.4 kJ/mol. A. Calculate the standard heat of formation (Hf) for Nitroglycerin. B. A standard does of nitroglycerin for chest pain is 60 mg. Given the equation in part a, determine the heat released when 60 mg decomposes (not explosively). C. Given the nitroglycerin melts at 3 C, would this compound be an ionic or molecular compound? Why?

Trinitroglycerin, C3H5N3O9 (usually referred to simply as nitroglycerin), has been widely used as an explosive. Alfred Nobel used it to make dynamite in 1866. Rather surprisingly, it also is used as a medication, to relieve angina (chest pains resulting from partially blocked arteries to the heart) by dilating the blood vessels. The enthalpy of decomposition at 1 atm pressure of trinitroglycerin to form nitrogen gas, carbon dioxide gas, liquid water, and oxygen gas at 25 °C is –1541.4 kJ/mol. (a)...
