Athousand kilos of soya beans, of composition 18% oil, 35% protein, 10.5% moisture and 36.5% other contents of carbohydrate ,fiber and ash are sent to a crusher, where it is crushed and pressed this reduces oil content in the beans to 6%, this extra amount of oil leaves the crusher; the oil-reduced beans then enter an extractor where hexane is added which in turn produces soya beans containing 0.5% oil; and finally the beans are sent to a dryer to leave with 8% moisture. assuming that there is no loss of protein and water with the oil, set out a mass balance for the soyabean constituents.

Which of the following pairs of elements belong to the same groupa. h and he b. li and bec. c and pb d. ga and ge

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
