Then we put the food coloring on top of the vegetable oil. Then we put the Alka-Seltzer in it. When it went in there it pushed the food coloring up into the vegetable witch made it go slow so it made bulbs of food coloring so it looked like a lava lamp. Why did this happen because‚ well the Alka-Seltzer reacted with the water naturally so the fizz pushed

to subdue this widespread virus‚ “a research group led by Saul Krugman and Joan P. Giles of the New York University School of Medicine initiated a long-range study of viral hepatitis at Willowbrook” (Munson‚38). This study‚ which will soon be discussed in further detail‚ consisted of intentionally infecting Willowbrook students with hepatitis‚ and was thus a very ethically controversial issue and continues to be so today. I will be portraying the facts of this study and discussing why I believe it

has a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared

Bread Mold Experiment By: Stephanie Westover PURPOSE The purpose of this experiment will be to determine how temperature affects the growth of mold on wheat bread. The researchers choose this topic because she thinks it will be beneficial to find a way to keep food from molding. Determining how long bread can be stored before molding can help save money‚ prevent illness and preserve freshness. The question the researcher will attempt to answer is how freezing

Introduction The presence of enzymes in our bodies controls the multiple events happening simultaneously by lowering the activation energy of chemical reactions. (1) These enzymes perform best under a certain set of environmental conditions. The purpose of this laboratory investigation is to examine the activity or horseradish peroxidase‚ an enzyme‚ under a wide range of circumstances and key
