________________________ Internal Assessment Criteria Aspect 1 Aspect 2 Aspect 3 Total DCP CE Aim: The aim of this practical is to plot and investigate the pH titration curves for the titration of a strong acid with a strong base and of a weak acid with a strong base‚ and find Ka of the weak acid. Procedure: Part I 1. Pour 30 ml of the HCl solution of unknown concentration in a 100 ml beaker. 2. Add a stirring magnet. 3. Place the beaker on the magnetic heater and activate the rotating motor but not

About an hour later I realized three things: (1) I had never truly completed a meaningful self-analysis‚ (2) This was going to take quite a bit longer than I intended‚ and (3) Just how important clearly and thoroughly completing a self-analysis & career outlook is. I continued to struggle generating meaningful thoughts‚ let alone putting something on paper. After a long break I came back to the assignment and realized

Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

Kimberly Shelton interviewed LTC Denehy‚ Deputy of G33‚ meaning that he falls under the G3‚ the head of USASOC Operations. He works alongside other Deputies to the G3‚ but focuses on current operations. LTC Denehy has been on Active Duty in the US Army for 23 years. He is pending battalion command‚ an honor in all communities‚ but especially in the Special Forces Community. His background is quite impressive. Originally from New Hampshire‚ he has taught at the United States Military Academy

one of two very similar pentose rings. Ribonucleic acids contain the sugar ribose. Deoxyribonucleic acids contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions. The Nitrogen-Containing Bases There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings
