To entertain children between the ages of 2 and 90, I enjoy
popping corks from bottles containing vinegar and baking soda.
I pour about 50 mL of vinegar into a 500-mL plastic bottle. Then I
wrap about 5 g of baking soda (which is sodium bicarbonate,
NaHCO3) in one layer of tissue and drop the tissue into the bottle.
I place a cork tightly in the mouth of the bottle and step back. The
chemical reaction generates CO2(g) that pressurizes the bottle and
eventually bursts the cork into the air. Everyone smiles.

in vinegar in baking soda
(a) Find the formula mass of acetic acid and of sodium bicarbonate.
(b) How many grams of acetic acid are required to react with 5 g of
NaHCO3?
(c) Vinegar contains ~5 wt% acetic acid. How many grams of vinegar
are required to react with 5 g of NaHCO3? The density of vinegar is
close to 1.0 g/mL. How many mL of vinegar are required to react
with 5 g of NaHCO3?
(d) Which is the limiting reagent when you mix 50 mL of vinegar
with 5 g of NaHCO3?
(e) Use the ideal
of CO2(g) are generated if P 5 1 bar and T 5 300 K. If there is
0.5 L of air space in the bottle, what pressure can be generated to
pop the cork?
