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. How is this equation developed? What does this equation tell about the reaction?

Question

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. How is this equation developed? What does this equation tell about the reaction?

aaronq · Answer

so write the equation and place 129 kJ on the appropriate side (it's an endothermic reaction).

i cant figure out what the equation would be .... this is an assignment from 2 months ago and i just got out of the hospital from a months stay an i dont remember any of this i had a lot of problems with a brain surgery i had and it affected my memory greatly

aaronq · Answer

sorry to hear that.

Its this: $NaHCO_3+129kJ\rightarrow Na_2CO_3+CO_2+H_2O$

i'll let you balance it

thank you im a lot better now then i was at least i dont have to take 8 medications anymore .... you seem like a really good person

aaronq · Answer

thanks. that's good, being on a lot of meds at once can't be too good for you.

anonymous · Answer

no it made me really weak

aaronq · Answer

:S 

well good luck with chemistry!

anonymous · Answer

thanks its a tough class when you have memory issues
