Using Stoichiometry to Determine Gases Produced in a Reaction Introduction Magnesium is a metal and is the third most commonly used metal by chemists. Some would say it is the least dense structural metal. Its lightness is often alloyed with aluminum. Magnesium is also used in racing car wheels called MAG wheels. Many car-manufacturing companies will use magnesium and aluminum because of the lightness of the metal. Both of these metals are reactive with acids. The most common acid in they

Title: Inhibition of Yeast Glycolysis Abstract: The purpose of this experiment was to study carbon dioxide emissions from yeast‚ as well as their respiratory rate and to use that data to study how glycolysis inhibitors affect the respiratory rate. In our experiment‚ we tested how 8.75% glucose + 1.25% NaCl‚ 8.75% glucose + 1.25% glucose-6-phosphate‚ 8.75% glucose + 1.25% citric acid‚ and yeast solution‚ all mixed with distilled water‚ affect carbon dioxide volumes and respiratory rate. Our results
