Question: With reference to the "Chemistry Put to Work" box on explosives,
(a) use bond enthalpies to estimate the enthalpy change for the explosion of 1.00 g of nitroglycerin.
(b) Write a balanced equation for the decomposition of TNT. Assume that, upon explosion, TNT decomposes into N2(g), CO2(g), H2O(g), and C(s).
What are some of these products? What is the chemistry behind these products, i.e. how do they work chemically? What are their specific uses?
