Chapter 3, Problem 75QP

When baking soda (sodium bicarbonate or sodium hydrogen carbonate, $\text{NaHC}{\text{O}}_{\text{3}}$) is heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread. (a) Write a balanced equation for the decomposition of the compound $\left(\text{one of the products is N}{\text{a}}_{\text{2}}\text{C}{\text{O}}_{\text{3}}\right)\text{. }\left(\text{b}\right)\text{ Calculate the mass of NaHC}{\text{O}}_{\text{3}}$ required to produce $\text{20}\text{.5gof C}{\text{O}}_{\text{2}}\text{.}$
