Question
(ans: -7.50 x 10 ) one mole of sucrose). Imol %3D 9reaction=n AH %3D %3D (ans: -5.64 x 10 kJ/mol) Calcium chloride and sodium hydroxide react according to the equation: CaCl(aq) + 2 NaOH(aq) → Ca(OH),(s) +2 NaCl(aq) What volume of 2.00 M NaOH would be needed to react with 50.0 mL of 1.50 M CaCl,? a, 017 (ans: 75.0 mL) b) When 50.0 mL of 1.50 M CaCl, solution and 80.0 mL of 2.00 M NAOH solution (i.e., 5.0 mL more than calculated in part (a)) both initially at 22.3°C are mixed in a coffee-cup calorimeter with a calorimeter constant of 12.8 J/ C, the temperature fell to 20.0°C. If the density of the reaction mixture is 1.03 g/mL and its specific heat 3.94 J/g°C, calculate the heat absorbed hv the reaction. (ans: 1.24 x 103) c) Calculate AH (in kJ per mole of Ca(OH)2 formed) for the reaction. (ans: 1.6 x 10' kJ/mol)
