1. Reaction stoichiometry: Consider the reaction for the complete combustion of butane (CaH10) in the presence of molecular (diatomic) oxygen, resulting only in the products CO2 and H2O. Answer the following questions- a. Write out the balanced stoichiometric equation for complete oxidation of butane to carbon dioxide and water. b. If a burner is continuously fed 12gr moles/hr of butane gas and a quantity of air sulficient for complete combustion, how many gr moles of CO2 and of H2O are exiting the process per hour? 2. Chemical process mass balance: Consider the toluene hydrodealkylation reaction that produces benzene and methane, as shown below. Determine the number of moles of all the species on the output stream of the process, if 85% of the toluene is converted to products benzene and methane. Toluene (TOL)+ Hydrogen (Hz) Benzene (BZ)+ Methane {CH4} 3. Mass balance with reaction and separation: Consider the process to make ammonia from gaseous hydrogen and nitrogen shown in the diagram below. 90% of the nitrogen present in the feed is converted to ammonia, and 95% of the ammonia ends up in the liquid stream output from the separator. Based on this information, what are the number of moles of each component in the vapor output and liquid ouput from the separator. Note that all the unreacted nitrogen and hydrogen end up in the vapor output, and none ends up in the liquid output from the separator
