Question

A 15.9 g sample of sodium Carbonate is added to a solution of acetic acid weighing 20 g. the 2 substances react, releasing carbon dioxide gas to the atmosphere and water. after reaction, the contents of the reaction vessel weighs 29.3 g. what mass of carbon doixide was released into the atmosphere during the reaction?​

Answer 1

hope that helps

Step-by-step explanation:

The total mass of reactants taken = 15.9 + 20.0 = 35.9 gm. From the conservation of mass the final mass of the contents of the vessel should also be 35.9 gm. But it is only 29.3 gm. The difference is due to the mass of released carbon dioxide gas.Hence the mass of carbon dioxide gas released = 35.9 – 29.3 = 6.6 gm
