bEAN BAG ISOTOPES:ABUNDANCE AND ATOMIC MASS LAB By: Catriona Whalley Partner: Ming Siegel Due: 1.14.10 Prelab A new atomic theory‚ in which all atoms of the same element are identical to one another and equal in mass‚ was proposed by the scientist Dalton. Although the theory had its flaws and was simple‚ it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon‚ isotopes were discovered‚ as atoms of the same element

the empirical formula of a metallic oxide. D) Pre Lab Questions: After heating the metal‚ the crucible and contents should mass less than it did before it was heated. This is because heating the crucible may rid of other residue that was left in it; bringing it a to a constant mass. A yellow flame will deposit soot on the crucible. This would be a problem because the soot left on the crucible would vary from our constant mass and cause our mass to be inaccurate. We have to heat the crucible

Roosevelt ’s New Deal The Great Depression started in the United states but spread into a worldwide economic down-turn. The stock market crash of 1929 caused Billions of dollars to be lost along with thousands of investors. It was the “deepest and longest-lasting economic downturn in the history of the Western industrialized world up to that time”(Stock Market Crash). Some say that this was a starting cause of the Great Depression. Over 20‚000 banks failed. On average “one out of four”(Living

Heat & Mass Lab 1: | | | 2/10/2011 2/10/2011 Executive Summary This experiment was conducted using a heat transfer unit. Many relationships were obtained and calculated from the observed results. To name a few; the log mean temperature difference‚ heat transfer coefficient‚ Reynolds‚ Nusselt and Graetz numbers. The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing

A&P Lab Exercise 1 1. Discuss how to protect yourself from body fluids‚ such as saliva and blood. You would protect yourself from other body fluids by first only working with your own body fluid. Second never allow body fluid to touch your skin. Always wear gloves and glasses when working with body fluids. Always assume that body fluids can infect you with a disease. Clean up body fluid spills with a 10% bleach solution/water and wear gloves when cleaning. 2. Why should you consider a body
