1. The addition of 3.27 g of Ba(OH)2 · 8 H2O to a solution of 1.14 g of NH4SCN in 175 g of water in a calorimeter caused the temperature to fall by 4.9°C. Assuming the specific heat of the solution and products is 4.20 J/g·°C, calculate the approximate amount of heat (in J) absorbed by the reaction, which can be represented by the following equation.

Ba(OH)2 · 8 H2O(s) + 2 NH4SCN(aq) → Ba(SCN)2(aq) + 2 NH3(aq) + 10 H2O(l)

-------- J
