Question

Sodium bicarbonate (NaHCO3) is often used in the kitchen to extinguish fires. When heated, it decomposes into sodium carbonate, water vapour and carbon dioxide. The delta H for the reaction of 1 mole of sodium bicarbonate is +64.6KJ.
a) Write a balanced thermochemical equation for this reaction.
b) Using the enthalpies of formation, calculate the enthalpy of formation of sodium bicarbonate
