Research: The balanced chemical equation would look along the lines of this:
NaHCO3 + CH3COOH NaCH3COO + H¬2O+CO2
For this lab, the reactants were baking soda (sodium bicarbonate, NaHCO3) and Vinegar (acetic acid, CH3COOH). And the products were sodium acetate, water, and carbon dioxide. I would expect to see, well obviously some kind of reaction, but from past science classes regarding the common household ingredients, baking soda and vinegar, the most common reaction was foaming and bubbling overflowing the container.
PV=nRT; whereas P=1atm, V= ?, n=1mol, r=0.0821, T=(20+273)K
If the experiment took place at room temperature within atmospheric pressure, we would see about 24.1Liters of gas, but the actual result will vary due to human flaws (error in reading or calculating, very precisely of the measurements).
