2. Baking soda is sodium bicarbonate (NaHCO3). When you heat baking soda, it breaks down into sodium carbonate powder (Na2CO3), water vapor, and carbon dioxide. The enthalpy of this reaction is 129 kJ. Write a correct thermochemical equation for this reaction, explain how you came up with this equation, and explain what it tells you about the reaction.

I really don't know what you want.
2NaHCO3(s) + heat ==> Na2CO3(s) + CO2(g) + H2O(g) delta H = +129 kJ.
