Flame Tests 12.01.2010 19.01.2010 Introduction The normal electron configuration of atoms or ions of an element is known as the “ground state”. In this most stable energy state‚ all electrons are in the lowest energy levels available. When atoms or ions in the ground state are heated to high temperatures‚ some electrons may absorb enough energy to allow them to “jump” to higher energy levels. The element is then said to be in the “excited state”. This excited configuration is unstable‚

The Spot-Overlay Ames Test was used in the lab to find the mutagenesis of Diet Coke and ThermaFlu. Along with these substances three mutant strains of salmonella were also tested. TA 1535‚ TA 1537‚ TA 1538 all lacked the ability to grow the amino acid histidine unless reverted back by the potential mutagens. After the first week of testing‚ results showed that both of the potential mutagens‚ Diet Coke and ThermaFlu were in fact mutagenic. This was established if colonial growth was at least twice

Abstract A tensile test was conducted on an Instron tensile machine using a 3/16 inch copper rod. Using data acquired stress and strain was calculated and plotted on Excel to analyze stress strain curve. Modulus of elasticity‚ 0.2% yield stress‚ ultimate tensile stress and % elongation were also calculated. Introduction A tension test is probably the most fundamental type of mechanical test you can perform on material. Tensile tests are simple‚ relatively inexpensive‚ and fully standardized
