October 30‚ 2014 Jordan Hollenbeck Juhn Borruel Electron Gun - Effects of a Magnetic Field Purpose: The objective of this experiment is to study the motion of an electron in a magnetic field and to establish (show/verify) a relationship between the magnetic strength and the distance the electrons are deflected. Theory and Procedure: The electron gun is an instrument that consists of an electron source (which emits electrons and focus the stream into a beam)‚ a magnetic coil (which uses a voltage

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient‚ pyruvate must be oxidized into carbon dioxide and water. This combustion of carbon dioxide and water to generate ATP is called cellular respiration (Tymoczko‚

Energy and Electron Affinity Ionization Energy is removing an electron Electron Affinity is adding an electron Ionization Energy • Energy required to remove an electron from a ground state atom Ionization Energy of Noble Gases • Noble gases have full orbitals‚ so it is difficult to remove an electron from them. But‚ it does become easier the further away the electrons get from the nucleus. Ionization Energy of Alkali Metals • Alkali Metals only have one valence electron‚ so it does

pairing of electrons take place in (n-1)d orbital causing repulsion i.e. shielding of (n-1)d orbital. Group 11 &12 elements i.e. Cu & Zn have bigger size due to strong shielding of completely filled (n-1)d orbital. The transition elements show variable oxidation state due to small energy difference between (n-1)d &ns orbital as a result both (n-1)d &ns electrons take part in bond formation. The highest oxidation state of an element is equal to number of unpaired electrons present in

Transport & Service costing Service Costing Unit costing is the method of costing used when the cost units are identical. Identical cost units should have identical costs and this concept of equality of costs is the basic feature of unit costing. It may be noted that process costs‚ output costing and service costing are the sub-divisions of unit costing method. Service Costing – Nature and Problem: Service or operating cost is the cost of providing services. Service costing

is about a young man named Harold Krebs who has just come back from the war. Throughout the story Krebs deals with many struggles within himself. He no longer has the effort to have a relationship with any of the girls in his hometown. Since he arrived much later than most of the soldiers‚ all the stories he wants to discuss are nothing but dull to everyone. His experience in the war changed Krebs and he doesn’t seem to acknowledge it. Deeper into the story‚ Krebs father makes it clear that no one

This essay will focus on some of advantages and disadvantages of public transportation. First of all‚ I’d like to talk about advantages of public transportation. Using public transportation can reduce the number of people who drive their own car. It can ease traffic jam and improve road condition. We can also reduce air pollution by using public transportation. Public transportation can accommodate a lot of people and send them various destinations. It leads to the reduction of harmful
