EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

The Separation of Powers were set to keep from having to much power. The U.S Constitution separated these powers into three different branches. The judicial‚ legislative‚ and executive are the three branches that each branch is separate and has independent powers. The powers that each branch is given‚ is so that they do not conflict with each other. To restrain one branch from becoming higher ranked than the other‚ checks and balances was brought into the picture. Checks and balances limits one branch

During the mid-1600’s England was a Christian dominated nation; the colonies‚ however‚ were mainly Puritans. When Sir Edmond Andros took over a Puritan church in Boston for Anglican worship‚ the Puritans believed this was done

Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography Aim: To analyze a mixture of alkenes by gas chromatography. Introduction: In this lab‚ we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids‚ alcohols protonate to form a good leaving group‚ namely water. Upon loss of a proton to a good leaving group‚ an introduction of unsaturation (a double bond) can be preformed. According to Wikipedia‚ an E2 reaction is typically

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences
