Sodium bicarbonate (NaHCO3) decomposes into sodium carbonate, carbon dioxide, and water. What is the theoretical yield of carbon dioxide, in liters, if 128 g of sodium bicarbonate decomposes? What is the percent yield for the reaction if 11.2 L of carbon dioxide is actually obtained when 128 g of sodium bicarbonate decomposes? 2 NaHCO3 → Na2CO3 + CO2 + H2O

moles NaHCO3 =
theoretical moles CO2 =
theoretical liters CO2 =
percent yield =

a graduated cylinder.

explanation:

i think slash and

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
