A Diels-Alder reaction of 2,5-dimethylfuran and maleic anhydride gives a compound A that undergoes acid-catalyzed(H2SO4) dehydration to give 3,6-dimethylphthalic anhydride. Could you please show the reaction in six steps with the curved arrow mechanism, show all the lone pairs,complete the structure of sulfuric acid or the hydrosulfate ion as necessary and complete each organic framework. Don't include the water.
If a breakdown of the thermal insulation around the turbine allows a heat loss of 60 kJ per kg of stream, and the exiting steam is at 150oC and 0.3 MPa, what will be the power developed by the turbine if the inlet steam conditions and flow rate ar..
