1) Brownian movement is a property of colloidal substances. Brownian movement is also known as pedesis. It is a random haphazard movement of particles suspended in a fluid. These movements are caused as a result of collision with other fast moving particles in the medium.

Dittusion of Molecules In this exercise you will investigate characteristics of molecules that facilitate diffusion, factors that influence diffusion rates, and diffusion of solutes through a selectively permeable membrane. Experiment A. Kinetic Energy of Molecules Materials dropper bottle of water slide and coverslip carmine powder (KM,04 compound microscope dissecting needle assim perman Introduction Molecules of a liquid or gas are constantly in motion because of the intrinsic kinetic energy in all atoms and molecules. In 1827, Robert Brown, a Scottish...
1.) Describe the goals of a Gel Filtration Chromotography Experiment??? 2.) Explain each key theoretical principle of a Gel Filtration Chromotography, and how they help acheive the goal???. 4.)

HI im trying to prepare for a lab/report and i have some questions i could use help with please :) over all having trouble seeing how everything ties together etc :) thank you...
Separating a Mixture, Recrystallization, pre-lab assignment could you also explain why you chose that substance for the empty spaces and question marks EXPERIMENT 4 Pre-Lab Assignment Separating a Mixture, Recrystalliration Name Date 1. Complete the following flowchart which shows how to separate a mixture of sand, sodium chloride and acetanilide. Notice that after a separation process (a down arrow) the filtered solids are shown on the left and the filtrate (the liquid) is shown on the right. The terminal step...
Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
