re-lab Assignment A mixture of sodium carbonate and sodium bicarbonate is heated. Sodium carbonate does not undergo any chemical reaction, while sodium bicarbonate loses cO2 and H20. Write a balanced equation for the reaction. What is the theoretical atom economy for the reaction? Sodium carbonate is the desired product and water and carbon dioxide are the waste products. A student heats 0.682g of a mixture of sodium caronate and sodium bicarbonate to a constant mass of 0.467g. What is the mass of sodium bicarbonate in the mixture? 1. 2. 3. What is the percentage mass of sodium bicarbonate in the mixture? 4-4 This lab is adapted from: Kristen L.
