Trinitrotoluene (TNT), the explosive used in dynamite, decomposes according to this reaction. 2C7H5N306(s)—700(g) + 7 C(s) + 5 H2O(g) +3 N2(g) In mining operations dynamite is sometimes used to remove excess rock. For this procedure the dynamite is placed in a drill hole having a volume of about 1.5 L. Calculate the total gas pressure produced when 1.00 lb of TNT is detonated? under these conditions. TNT detonation temperature is 3500 K. Respond with the correct number of significant figures...
