After completing the poverty simulation‚ I learned that it is very hard to live to on a paycheck to paycheck scenario. I also learned that anything can happen at any given moment that can cause you to miss hours at work or use more money than budgeted. In this they threw out many different curve balls that caused you to make tough decisions that people are faced with which made it all the more real. I also learned a few statistics that may be outdated but looking at the numbers put the situation

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

The PCR reaction mixture consisted of 5 μL DNA (10 ng/μL)‚ 5 μL of 10X PCR buffer‚ 2.5 μL MgCl2 (50 mM)‚ 2.0 μL dNTP’s (2.5 mM each)‚ 4.0 μL each primer (5 μM)‚ 0.3 μL Taq DNA Polymerase (5 UμL-1‚ Invitrogen)‚ 0.5 μL formamide‚ and 26.7 μL Milli-Q water in a total volume of 50 μL. The enzymatic amplification wasperformed using an automated Veriti Thermal Cycler (Applied Biosystems). Prior to PCR cycling‚ the reactions were incubated at 94 °C for 1 minute to fully denaturate the DNA. Afterwards

Calorimeter Determination of Reaction Enthalpy 9/11/2014 Introduction: A chemical reaction often indicated by a transfer of energy measured in heat. By measuring this heat transfer in a constant pressurized environment‚ the enthalpy of the reaction can be used to infer certain information about a specific reactions reactants and products. The transfer of heat from outside sources in would be described as an endothermic reaction. Contrary‚ when a reaction releases heat out to its surroundings
