Name: Taylor Wright Lab Partners: Cody‚ Jeremy‚ Haly‚ Eric‚ Brody Date: October 14th Class: Chemistry 20 Charles’ Law Lab Introduction: The purpose of this investigation is to demonstrate how water temperature affects the volume of a balloon. According to Charles’ Law‚ temperature and volume increase proportionally‚ as long as chemical amount and pressure remain the same. Research Question: How does the volume of a balloon react to changing temperatures? Hypothesis: If we increase the temperature

1) Using tweezers remove individual plants from the soil and remove the roots with scissors. Measure the weight of each individual and place in a 1.5 mL microfuge tube. Place this tube directly into liquid N2 to freeze plant tissue. 2) Remove tubes from the liquid N2 and quickly grind the plant tissue with a pestle. Add 300 L of Methanol 1%HCl and continue to grind the plant tissue. Allow extraction to occur overnight in a dark refrigerator. 3) Add 200 L Milli-Q H20 to each tube. Next

Separation of a Mixture Introduction: Mixtures are not unique to chemistry; you use and consume them on a daily basis. The beverages you drink each morning‚ the fuel you use in your automobile‚ and the ground you walk on are mixtures. Very few materials that you encounter are pure. Any material made up of two or more substances that are not chemically combined is a mixture. The isolation of pure components of a mixture requires the separation of one component from another.

Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any
