- - The major objective of a roasting process is to eliminate the Sulphur contained in the concentrate andto provide a calcine. In a roasting plant, 1000 kg per hour of molybdenum(IV) sulphide (MoS2) is roastedwith 25 % excess air to obtain MoO3 calcine in a chamber-type roasting furnace. Preheated air entersthe reactor at 400 K while MoS2 enters at room temperature. After the process, the waste gases leavethe reactor at 1000 K, and the calcine leaves at 850 K.a) Draw process flowsheet and heat balance diagram (ref. temp is 298 K) b) Calculate the amount of off-gas per hour in moles. c) Calculate the amount of calcined MoO3 per hour in kg.Jansen Gas creates three types of aviation gasoline(avgas), labeled A, B, and C. It does this by blendingfour feedstocks: Alkylate; Catalytic CrackedGasoline; Straight Run Gasoline; and Isopentane.Jansen’s production manager, Dave Wagner, hascompiled the data on feedstocks and gas types inTables 4.6 and 4.7. Table 4.6 lists the availabilitiesand values of the feedstocks, as well as their keychemical properties, Reid vapor pressure, and octanerating. Table 4.7 lists the gallons required, theprices, and chemical requirements of the three gastypes.

She purchased bell peppers of different colours from local wet market. Bell pepper samples were cut, blended and homogenized with a fixed portion of water. Subsequently, coulometric titration was performed using iodine under constant current of 60 mA. In one of the experiment replicate,starch end point was achieved after 18 minutes. Suppose that bell pepper sample recorded initial mass of 115 g, deduce it’s vitamin C (176 g/mol) content in percentage. (F = 96500C)2.

If double amount of air (mole basis) was supplied in the reactor then find the average molecular weight of the outlet gas mixture stream. Note that, carbon has no reaction with nitrogen in this case.The capacity of batteries such as the typical AA alkalinebattery is expressed in units of milliamp-hours (mAh). AnAA alkaline battery yields a nominal capacity of 2850 mAh.(a) What quantity of interest to the consumer is beingexpressed by the units of mAh? (b) The starting voltage of afresh alkaline battery is 1.55 V. The voltage decreases duringdischarge and is 0.80 V when the battery has delivered itsrated capacity. If we assume that the voltage declines linearlyas current is withdrawn, estimate the total maximumelectrical work the battery could perform during discharge.
