The addition of 3.15 g ofBa(OH)2•8H2O to a solution of 1.52 g of NH4SCN in 100 g of water in a calorimeter caused the temperature to fall by 3.1 °C. Assuming the specific heat of the solution and products is 4.20 J/g°C, calculate the approximate amount of heat absorbed by the reaction, which can be represented by the following equation: Ba(OH)2-8H20 + 2NH,SCN Ba(SCN)2 + 2NH3 +10H;O O 136.28 J 1.3628 J O 1362.8 J

Question
The addition of 3.15 g ofBa(OH)2·8H2O to a solution of 1.52 g of NHĄSCN in 100 g of water in a calorimeter caused the temperature to fall by 3.1 °C. Assuming the specific heat of the solution and products is 4.2O J/g°C, calculate the approximate amount of heat absorbed by the reaction, which can be represented by the following equation: Ba(OH)2-8H,0 + 2NH,SCN Ba(SCN), + 2NH3 +10H,O O 136.28 J 1.3628 J O 1362.8 J
