5. Give electron configuration and orbital diagram cl (chlorine) (10p) 6- Arrange the elements Mg, S, and Cl in order of decreasing electronegativity (10p) 7. Write the Lewis structures for CCI (C is the central atom) (10p) Predict the geometry of the molecule (10p) 8-Give the hybridization of CH4 9. When Calcium chloride (CaCl) added to water, it dissolves: CaCl (s) Ca+(aq) + 2Cl2(aq) A calorimeter contains 50.0 g of water at 25.00C. When 1.00 g of calcium chloride is added to the calorimeter, the temperature rises to 28.51C. Assume that all the heat given off by the reaction is transferred to the water. (10p) a) Calculate q for the reaction system. b) How much CaCl, must be added to raise the temperature of the solution 9.00C
