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?

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)...

A request has been received from an external customer for recommendations for linear position control sensors to be used in an explosive environment. For this reason unsafe electrical contacts must be avoided. The sensors will be installed in locations that are hazardous to access except when the plant is shut down annually for maintenance. The span required is 5 cm. The sensor case must not permit any ingress of dust or of water. State what type of position sensors...

While the Capital Asset Pricing Model (CAPM) has been widely used to analyze securities and manage portfolios for the past 50 years, it has also been widely criticized as providing too simple a view of risk. Describe three problems in relation to the definition and estimation of the beta measure in the CAPM that would support this criticizm.

***For years, it has been widely recognized that TV has the potential to be the greatest educational device in history. (This includes not just what is presently considered educational TV but commercial TV as well.) Does the TV industry have any moral obligation to realize that potential? If so, explain the source of that obligation and the kinds of changes in present programming that would be necessary to honor it.
