Trinitroglycerinn (C3H5N3O9) (usually referred to as nitroglycerin or TNT) has been widely used as an explosive. Alfred Nobel used it to make dynamite in 1866. It also has medicinal applications and is used to relieve chest pain from partially blocked coronary arteries. At 1 atm pressure and temperature 25 C, the enthalpy of decomposition of this compound to form nitrogen gas (N2), carbon dioxide gas (CO2) , liquid water and oxygen gas (02) is -1541.4 kJ/mol.

a. Write a balanced equation to describe the decomposition of nitroglycerin.

b. Calculate the standard heat of formation (Hf) for nitroglycerin.

c. A standard dose of nitroglycerin for chest pain is 60 mg. Given the equation in part a, determine the heat released when 60 mg decomposes (not explosively).

d. Given that nitroglycerin melts at 3 C, would this compound be an ionic or molecular compound? Why?

Solutions

Expert Solution

D) as TNT decompose melts at 3 degree Celsius.

this implies this is a molecular solid, because Ionic solids have a very high melting point due to strong intermolecular forces of attraction.

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)...
