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 =
