Answer to Question #190921 in General Chemistry for mel

Question

THE AIT BAG EXPERIMENT:

1.the balanced chemical equation for the reaction of sulfuric acid and sodium bicarbonate is:

Na₂SO₄ + H₂O + CO₂

2.the volume of the bag (in liters): 1.20L

3.pressure: 1.0 atm

4.temperature: 23.0 degrees

5.calculate the moles of carbon dioxide needed to fill the bag using the ideal gas law (PV=nRT) equation. Show the calculations:

1x1.20/(0.082x296) = 0.05 moles

6.calculate the grams of sodium bicarbonate needed to generate enough carbon dioxide to fill the zip-lock bag taut with an excess of sulfuric acid. (show calculations)

7.calculate the mL of sulfuric acid needed to generate enough carbon dioxide to fill the zip lock bag taut with an excess of sodium bicarbonate:(show the calculations)

answer questions 6 and 7.

Answer 1

Mass of Sodium Carbonate needed =44.2g

mL of sulfuric acid needed =325mL
