I. Carbon Dioxide Lab
II. Purpose:   The purpose of this lab was to find out how much Carbon Dioxide is produced from each gram of calcium carbonate.
III. Sources of Error: 1. Scale plus or minus 0.01
2. graduated cylinder + or – 1 milliliter temperature
3. atmospheric pressure
IV. Research: 1. Limestone is formed when carbon dioxide combines with acid precipitation to make carbonic acid and falls into the ocean. The acid reacts with calcite and the pressure of the water above combines with man shelled animals to make limestone. The equation for limestone is H20+CO2+CaCO2~Ca2+2HCO                     2. TUFA formula is a type of limestone formed by the precipitation of carbonate materials. Standard form of C02 minus standard conditions of zero degrees Celsius and one atmosphere of pressure carbon dioxide exhibits a density of 0.001977 g/mL.
3.The density of C02 at STP(standard temperature pressure) is 44/22.4 also known as 1.96 grams per liter.

      IV.       Hypothesis: The hypothesis of this lab is that the density of C02 is approximately      
                  0.002149 grams per milliliter
      V.       Materials:
                1. two 100 meter graduated cylinders
                2. a flask
              3. large plastic(clear) bucket filled 2/3s of the way with clean water
              4. one 250 milliliter beaker
              5. one small shell
              6. hydrochloric acid
              7. long rubber tube
            8. rubber cork (with a whole in the thick end)
VI.       Procedure: (read all of the procedure before attempting to try lab and record all data on a sheet of paper)
1. Find the mass of the shell
2. Fill the flask with hydrochloric acid ( drop shell inside)
3. Connect rubber cork to rubber tube (secure it)  

4. Fill up both cylinders with water until they overflow
5. Turn one upside down with...
