When 3.00 g sodium carbonate (K2CO3 ) was mixed with 20.0 mL of hydrochloric acid (HCl, 2.0M) in a calorimeter, the temperature raised 3.0 oC.
a. Write down the balanced reaction equation between K2CO3 and HCl.
b. Calculate the enthalpy change (H) of the reaction for per mole patassium carbonate. Assume the specific heat of all solutions are 4.18 J/g.oC and all solutions have a density =1.0 g/mL.(10.2kJ/mol)
