Organic Chemistry Project: Designing molecules In order to understand the complexity and shape of an organic molecule you and your partner will be constructing a 3-D version of a selected organic compound. The project will have four parts: A blueprint of the molecule you will construct The molecule A legend explaining the structure of the molecule A paragraph explaining the importance of the molecule This project will count as one lab grade. A sample grade sheet is on the back.

Isotopes and average atomic mass Isotope: element variations with different atomic mass but same atomic number Isotopic Abundance: the relative amount in which each isotope of an element Calculating: given 2 isotopes of an element [B: 10.01u] [B: 11.01u] 1) Given average atomic mass: 10.81u If given percentages‚ you can find average atomic mass by adding each portion 2) Set variables for unknown values Let x represent % abundance for 10/5 B Let 1-x represent % abundance for 11/5 B Calculate:

Are laboratory experiments useful? Laboratory experiments are easy to replicate and help to find how the Cause and effect of relationships can be established. Laboratory methods usually have High levels of control over extraneous variables. One of the major strengths of laboratory experiments is‚ control. The more variables you have control over‚ the easier it becomes to draw conclusions about the effect of the individual variable on the dependent variable. Laboratory experiments allow for high

Comparison of “Hitcher” and “The Laboratory” Despite being written almost two centuries apart both ‘The laboratory’ and but Robert Browning and ‘Hitcher’ but Simon Armitage deal with themes of jealousy‚ resentment and violence as well as many other similarities and differences. ‘Hitcher’ is about a depressed man who is deeply angered and takes his frustration out on an innocent hitch hiker spontaneously. ‘The Laboratory’ is about a woman who‚ driven by jealousy‚ wants to poison her husband’s

conclusion by different paths and‚ at first‚ without working together‚ both Lord Rayleigh and Sir William Ramsey succeeded in proving that there must exist a previously unknown gas in the atmosphere. They subsequently worked in their separate laboratories on this problem but communicated the results of their labors almost daily. At the meeting of the British Association in August 1894‚ they announced the discovery of Argon. They found the gas by isolating a small sample of the nonreactive portion

Chemistry Review (mid-term) 1. Use the equation for atomic mass to answer the following questions. (http://johnheilchem10.escuelacampoalegre.wikispaces.net/file/view/average+atomic+mass+calculations+-+3.pdf) 1. Argon has three naturally occurring isotopes: argon-36‚ argon-38‚ and argon-40. Based on argon’sreported atomic mass‚ which isotope do you think is the most abundant in nature? Explain. 2. Copper is made of two isotopes. Copper-63 is 69.17% abundant and it has a mass of 62.9296 amu.

This case study describes what happens when a health district merges four laboratories into one unit due to external driving forces for change‚ primarily the government funding cuts. Although the intention was to develop one centralized‚ efficient‚ and high volume centre‚ the inattention to the ‘people issues’ and the cultural differences of the work units results in chaos. The recently hired laboratory manager‚ Claude‚ has implemented several stopgap measures intended to address the work load issues
