A sample of 14.5 g of sodium bicarbonate (NaHCO3) was dissolved in 100 ml of water in a coffee-cup calorimeter with no lid by the following reaction

NaHCO3 (s)    →     Na+ (aq)     +     HCO3- (aq)

If the temperature of the water and the calorimeter (heat capacity of calorimeter = 150 J/oC) decreases from 25.00oC to 19.86oC, (1) what is the ΔH of the reaction?  Using the definitions at the beginning of the module describe (2) the calorimeter + contents, (3) the type of process.
