The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

being displaced to for CO2 2-C. Similar to the limewater‚ the bromthymol blue is being displaced to form CO2 2-D. When I combine the H2O2 mixture with sodium bicarbonate with a light match‚ it extinguishes the fire. 3-F. When I mixed the alka seltzer tablet with the limewater it rapidly increased the volume in the well plate of the limewater mixture which means that it produces CO2 in the limewater. 4-C. I noticed no changes between the limewater and my breath through the straw.

Which Antacid Works the Best? Heartburn is a condition characterized by a burning feeling in the chest and a sour or bitter taste in the mouth. Heartburn usually develops when the acidic contents of the stomach flow back‚ or regurgitate‚ into the esophagus‚ the muscular tube that carries food from the throat to the stomach. Approximately one in ten adults experience heartburn once a week. Heartburn is more common in pregnant women because of the pressure the expanding uterus exerts on the stomach

Lava Lamp Science Investigatory Project Submitted by: Keanu Kent B. Gargar IV – St. Ezekiel 10/7/13 Introduction A lava lamp (or Astro lamp) is a decorative novelty item‚ invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive
