Plzz write a small pharghraph
Question:
A 250mL Erlenmeyer flask weighing 55g contains 5g of sodium bicarbonate. To this, an excess, 15g, of acetic acid is added to the flask. While swirling, many bubbles are present. Finally, you stop swirling the flask, and the bubbles stop. You then place this flask on an analytical balance. The mass registers 73g.
How does this final mass compare with the value expected according to the Law of Conservation of mass?
Why do you believe that this comparison exists?
State the Law of Conservation of Mass. Do these results break this law? Why?
What changes, if any, could be made to the procedures in this experiment to allow a closer comparison to what the Law of Conservation would expect?
