oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the theoretical and the experimental standard electrode potentials. The sources of error are incorrect solution preparation and contaminated materials

BIOL 3810-504 Compound Action Potentials Date Performed: 15FEB2011 Date Due: 01MAR2011 Introduction Neurons are the cells that receive and transmit electrical signals (University of North Texas‚ 2010). The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a graded response that results from

an electric light and a dark room becomes bright. Turn on a music player and sound comes through your headphones. In both situations‚ energy moves from one place to another; effect and reaction. The two different types of energy are kinetic and potential energy. Kinetic energy is the energy a moving object has because of its motion. The kinetic energy of a moving object depends on the object’s mass and its speed. The kinetic energy of a moving object can be calculated from this equation: Kinetic

The Message of the Black Ball The Story “The Black Ball” written by Ralph Ellison is about a man named John‚ born around the civil war that goes through difficulties and challenges in his life him being an African American. In the story‚ it seems like it’s just a straight forward story but if you take a real close look at it you can see that there is a message within the story. Through Metaphors and allegories and other literary terms like characterization‚ you can see the negative of how

Why do I want to go that far? It is because‚ I love this country and I want to bring Malaysia and the Malaysians to the next level. Malaysians had enough of being in a developing country. Why do I set that as my goal? I believe 90% of Malaysian will agree with me that the

Resting potential is created by a transport protein called the sodium-potassium pump. Resting potential occurs when ions are distributed unequally on the inside and outside of cells‚ and when cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition‚ the inside of the cell has a high concentration of K+ and the outside of the cell has a low concentration of K+. K+ will naturally diffuse

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement

For your Test on Thursday‚ study text chapters 1 thru 6. Potential questions include the following: Be able to define‚ explain the characteristics‚ and compare the differences between Economic Growth and Economic Development. Tied to this question‚ or perhaps‚ as another potential question‚ be able to discuss the various reasons "why some countries are poor." Chapter 2 concerns itself with the problem of measuring economic growth. As another possible question‚ consider the standard
