Answer:

I think you may address a decomposition reaction...

Explanation:

And so we got...

#underbrace(2NaHCO_3(s))_"168.02 g" stackrel(Delta)rarrunderbrace(Na_2O(s))_"62.0 g" + underbrace(2CO_2(g))_"88 g"uarr+underbrace(H_2O(g))_"18 g"uarr#...

...and so at least with respect to the starting sodium bicarbonate, MASS LOSS is observed...i.e. evolution of carbon dioxide, and gaseous water. And I have ASSUMED that decomposition is quantitative under the conditions...
