Solvent/Water Trap Diagram Rodney Atwaters Halle Bair May 28‚ 2013 Chemistry 36100 Introduction The purpose of this lab was to produce benzoic acid by mixing sodium benzoate with hydrochloric acid. The Hydrochloric acid used in the experiment was a stock solution made by mixing HCl Acid and deionized water. HCl acid‚ historically called‚ muriatic acid or spirits of salt‚ hydrochloric acid is produced from sulfuric acid and common salt‚ NaCl (Princeton.edu). Since the early 1900 ’s‚ sodium

The DSM 5 The Diagnostic and Statistical Manual of Mental Disorders (DSM) is almost like a bible to the likes of clinicians‚ researchers‚ insurance companies and many more. Ever since the very first edition back in 1952‚ there have been many debates and controversies surrounding the book. When the first edition came out‚ it contained 106 mental disorders in its pages which almost doubled by the time the 4th edition came by in 1994 with 297 disorders. Here we are at

1. Distinguish between primary groups and secondary groups. Provide examples of primary and secondary groups to which you belong. Primary groups display a personal orientation‚ people in secondary groups have a goal orientation. Primary group members define each other according to who they are in terms of family or personal qualities‚ but people in secondary groups look to one another for what they are. Some examples would include living in a suburb area. People including myself tend to interact

points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

Hypothesis: Experimenter thinks the order of the solutions according to their concentration is D‚A‚E‚C‚B‚ from smallest. And the water will pass through semipermeable tubing bag from low to high concentration to thin the concentration inside the bag. Osmosis is a diffusion of water particles and is one of the passive transport
