n this exercise, weighed samples of a solid unknown containing NaCl and NaHCO3 react with hydrochloric acid. The volume of the CO2 liberated by the reaction in the gas phase is measured with a gas collection syringe. From the volume we can calculate the number of moles of CO2 in the gas phase using the ideal gas approximation. Since the CO2 is generated in an aqueous environment (aqueous HCl), some CO2 will dissolve in the liquid phase. The amount of...

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...
