Name: Serene Tan Subject: Chemistry SL Date: 5th December 2012 Title: The effect of concentration of electrolyte on the potential difference in voltaic cell. Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives

Least Intensive Interventions Mnemonic Device Teach the student strategies to write lengthier stories with organized content. Use a mnemonic device such as “WWW‚ What = 2‚ How = 2” which translates into a story grammar checklist: WHO is the main character; WHERE the story takes place; WHEN the story occurs; WHAT the main character(s) do or plan to do; WHAT happens next; HOW the Story oncludes; and How the character(s) feel about their experiences.

to start class today talking about cells. Believe it or not‚ each and every one of you came in contact with cells over the weekend. The most important thing to remember is this: cells make up living things. They make up us‚ our families‚ our dogs‚ and even the trees that provide shade to your front yard. Today we are going to focus on the cells that make up our bodies. Your skin‚ brain‚ muscles‚ bones‚ and every other part of your body is made up of cells. Cells are the basic building blocks of all

Blaber Electrochemistry Commercial Voltaic Cells Voltaic cells provide a convenient‚ safe and portable supply of electrical energy. The Industrial Revolution marked the development of heat engines‚ and other devices‚ that utilized the energy released from combustion reactions in the form of heat The Digital Age (Electronic Revolution?) revolves around devices that require energy in the form of electrical energy. Such devices require voltaic cells and redox chemistry (as opposed to gasoline and

Cell Phone Policy Implementation The cell phone policy I would create will not be broad for its usage. I will also put the responsibility into the users hand and will monitor it monthly. I would begin by including members of management‚ human resources‚ technology support‚ general staff and legal department. Discuss the current cell phone environment to determine the need of cell phones. That will create a list of eligible employees for either smartphones for data usage and applications or just

Dangers of Cell Phones I am sure that most of you own cell phones and that you can’t leave your home without it. And that all of you think of cell phones as one of the most useful devices of our time. Despite all that‚ have you ever considered dangers of using cell phones or thought about the harmful effects of the microwave radiations? (Pause) Just 10 years ago‚ cordless telephones were something used only by big businesses and privileged persons‚ but Nowadays; it seems that every kid

concentration in electrolytes on the potential difference in a voltaic cell Introduction When two electrodes made of different metals are connected together in a voltaic cell‚ the chemical energy present is converted into electrical energy and an electromotive force is generated. This force‚ called the electrode potential‚ is normally measured under standard conditions‚ which is 298K‚ 1 mol dm-3 solution for the electrolyte. However when one measures the electrode potential in a voltaic cell‚ the conditions

Experiment 4: Extraction and Chromatic Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components need to be isolated. The two main pigments in tomato paste mixture are the yellow-orange β-carotene and the red lycopene. The colors
