Battery Light Lab Report

the chemical energy stored in batteries gets transformed into electrical energy through the wires, then gets transformed into light energy and thermal energy that you see.

In this project, C. Elegans are hermaphrodite worms that will be used since they are easy to maintain in lab, as well as have short life cycles. The gene that the project attempted to knockdown in C. Elegans with RNAi treatment is the unc-22 gene. RNAi disrupts gene expression in the presence of double stranded RNA (dsRNA) that is complementary to target gene sequence. The unc-22 gene codes for a muscle protein called twitchin in wild-type worms. The Unc-22 is required for muscle regulation and maintenance in C.Elegans. To verify that the RNAi treatment worked, would check the unc-22 mRNA levels in the worms, in addition to phenotype observation.

The mean voltage of the battery terminals while connected to the identification resistors is presented in Figure ‎4 12. These samples have been pulled out from the voltage sensor of the PEB panel. The voltage decreased as expected from 12.53 to 12.5 during first 20 seconds of connection to the

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Introduction: Voltage can be thought of as the pressure pushing charges along a conductor, while the electrical resistance of a conductor is a measure of how difficult it is to push the charges along. Using the flow analogy, electrical resistance is similar to friction. For water flowing through a pipe, a long narrow pipe provides more resistance to the flow than does a short fat pipe. The same applies for flowing currents: long thin wires provide more resistance than do short thick wires. The resistance (R) of a material depends on its length, cross-sectional area, and the resistivity (the Greek letter rho), a number that depends on the material. The resistivity

Chemiluminescence is a reaction well known to those who enjoy crime scene shows. Luminol is first synthesized in the experiment. Then, the crude luminol produced is oxidized to release photons giving off a light blue glow in a dark room. In a crime scene show, the blood acts as a catalyst aiding in the oxidation of luminol and hydrogen peroxide resulting in the blue glow 1.

According to Burton Leiser subjects shouldn't be punished until proven guilty, claiming that criminals who committed serious crimes “deserve” punishment. Leiser states, “Only the most horrendous offense against the state who seems to deserve the ultimate penalty”. Concluding his argument without giving any justification as to what constitute as a horrendous offense deserving of the death penalty. Bedau, on the other hand, explains retribution, by using Leiser’s argument in a sentence “Some murders seem improperly punished by death at all; other murders would require methods of execution too horrible to inflict; in still other case any possible execution is too deliberate”. The implications doesn’t ask us, to disregard the death penalty, moreover

This is done through a change in temperature. Over time, two objects that are in direct contact will

Abstract In lab, luminol was synthesized by reacting 5-nitro-2,3-dihydrophthalazine-1,4 dione with sodium hydroxide, sodium hydrosulfite, and acetic acid. Once synthesized, luminol was added to various mixtures in which a catalyst such as potassium ferricyanide, as well as the addition of hydrogen peroxide caused chemiluminescene to occur. This change in an excited state to a ground state in the product produced a fluorescent blue light, especially in the concentrated solutions of A and B. Introduction The purpose of the experiment was to synthesize luminol and observe its chemiluminescent properties.

Covered in this laboratory report is the synthesis of Luminol and the reaction of chemiluminescence. We synthesized Luminol by process of reducing 5-nitro-2,3-dihydrophthalazine-1,4-dione with sodium hydroxide and sodium hydrosulfite and then proceeding to oxidize the product. Equipment and techniques used for the reaction were reflux and a vacuum apparatus, which yielded a solid Luminol precipitate of 0.181g. After producing two separate stock solutions, the Luminol along with the stock solutions were taken into a dark room to observe the blue light emission. Introduction: By definition, chemiluminescence is a chemical reaction in which light is released without heat being released.1

Description of Experiment/Investigation Purpose: The purpose of this lab was to be able to see the various ways that light interacts with different surfaces. The lab shows how incident light rays can be absorbed, reflected, and refracted based upon the object with which it comes in contact. Description of the Use of Materials: For this lab, a flashlight was needed to represent a beam of incident light and to test how the beam coming from the flashlight interacted with various materials. In addition, the room had to be dark for optimal results in seeing the incident light. To test the reaction of the light with various objects: a comb, a white piece of paper, a triangular prism, a CD, powder, mirror, wax paper, tissue paper, glass of water,

Patient #1 will need several lab and diagnosis test ran on the current medication list. A CBC and culture & sensitivity test is needed for the Vantin to determine if still needed for bacterial infection. Potassium level along with renal function, bicarb and pH level should be monitored for mineral and electrolyte replacement of potassium Chloride. Furosemide (Lasix), which is a diuretic, is being administered 40mg PO daily. Electrolytes, renal function, hepatic function, glucose levels along with uric acid level should be checked before therapy begins. Also, check for decrease in potassium, sodium, calcium and magnesium. Patient #1 is on several benzodiazepines Librium 25mg Q8h, Ativan 1mg every 1-2hrs orally as needed. And Serax 15mg

This one had red wires which transmitted current to two LEDs in parallel in order to light them up. Each LED had two 220Ω resistors through which the current exited the LED and green wires that led the current to ground. After calculating this circuit’s values, we used both the resistance equation and Ohm’s Law the same way we had for the first circuit (separating the two LEDs into different circuits and for Ohm’s Law using only the current which passed through the branch). This gave us 106Ω as the resistance of the red LED and 107Ω as the resistance of the green

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

When you are recording the procedures you first have to read over the procedures given to you in the lab manual. After reading the lab you need to have some understanding of what the experiment is asking the experimenter to do. Once the goal of the experiment is determined you can then begin to write in your own words the steps necessary steps to complete the entire experiment. This is important because the lab manual uses terms that students may not be familiar with and if copied directly the student may miss a step or complete a step wrong giving them wrong information which creates a different result. While trying to complete all of my required classes for my major, procedures are important because I must complete classes in a certain order
