a.) Write the balanced equation for the reaction to synthesize trans-[Co(en)2Cl2]Cl. b.) what is the purpose of aerating the solution containing CoCl2*H2O, hydrogen peroxide, and ethylenediamine? c.) What safety issues must be taken into consideration? Solution (a) The balanced equation is: 4 CoCl 2 . 6 H 2 O + 8 en + 4 HCl + 2 H 2 O 2 = 4 [Co(en) 2 Cl 2 ]Cl + 28 H 2 O (b) The mixture is aerating to oxidise Co +2 to Co +3 (c) Safety issues: 1. Chemicals must be handled wearing lab coats and gloves. 2. En (ethylene diamine ) is carcinogenic, so read the instructions before use. 3. use safety goggles. 4. Do the reaction inside safety hood. .

Abacus Co. wishes to maintain a growth rate of 12.4 percent a year, a debtâ€“equity ratio of 1.2, and a dividend payout ratio of 28 percent. The ratio of total assets to sales is constant at 0.92. What profit margin must the firm achieve? Solution Equity multiplier = (1+ debt equity ratio) = 1+1.20 = 2.20 ROE = profit margin x turnover x Equity multiplier = profit margin x 1/0.92Â Â x 2.20 Growth rate = ROE x (1- payout ratio) 0.124 = profit margin x 1/0.92Â Â x 2.20 x (1-0.28) Proit margin = 0.124 x 0.92 / (2.2 x 0.72) = 7.20% .

Oxygen Iron Sulfur Aluminum Iodine Carbon c. Which elements are chemically similar to each other? Lithium Oxygen Lead Manganese Potassium Silicon Solution a) Bromine and iodine are chemically similar. Both comes in group 7A and have almost similar properties. Eventhough fluorine also is in group 7A, it is different from the other two because of its small size and high electronagativity. b) Oxygen and sulphur. They belong to group 6A of the periodic table. They both have six valence electrons. c) Lithium and potassium. They belong to group 1 and contains one valence electron. .

Air, initially at 220 kPa and 450 K undergoes a polytropic state change to 374 kPa and 495 K. What is the polytropic exponent of this process? and Saturated water vapor is contained in a rigid container. Heat is then added until the the pressure and temperature become 861.818 MPa and 400 ?C, respectively. What was the initial temperature of the steam? ?C Solution PV n =C PV=nRT V= nRT/P P( nRT/P) n =C P 1 (T 1 /P 1 ) n =P 2 (T 2 /P 2 ) n (T 1 P 2 /T 2 P 1 ) n =P 2 /P 1 n= ln(P 2 /P 1 )/ln(T 1 P 2 /T 2 P 1 )= 1.218944 .
