Mineral Lab Paper Week One Mineral Lab Geology SCI/245 Axia College Mineral lab Paper The four requirements for minerals are that they must be naturally occurring in other words they must appear in nature something that that was formed by the earth and not man made. It must be inorganic which means I must not be formed from an organic substance like a fossil of any other living creature. It must have a specific crystalline structure that is formed from simple salts and complex silicates

Background Information: When working in a lab‚ scientists often need to identify different molecules that are present in a sample they are studying. There are many ways to identify unknown molecules/chemicals in a sample. The method you will be using today is called Paper Chromatography and consists of 2 steps. First‚ you will separate the unknown chemicals and then you will identify

distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had the high boiling point of 110 degrees Celsius. Gas chromatography was also preformed

Averi Schwartz 10/27/10 Communication Lab Paper “Fashion week is a fashion industry event‚ typically named after the host city or major commercial sponsor (New York)‚ lasting four to ten days. It is held so that fashion designers are able to showcase their “collections” for either spring or fall seasons to consumers” (definition) (Indvik). In New York‚ it is referred to as the Mercedes- Benz Fashion week because they sponsor fashion week every year. Fashion week happens twice a year in February

Gas chromatography (GC) is a type of chromatography that uses a carrier gas as the mobile phase and a column as the stationary phase. The sample is injected into the instrument and is heated until the sample‚ which includes both analyte and solvent‚ boils. The analyte must have

experiment is to identify an unknown proprietary drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done

Introduction and Theory: A two dimensional object is a figure that has both width and height. Today in physics a two dimensional lab was done to decide the distance of an ice cream cone shooter. To do this‚ the formula (d=Ví t + (1/2) at^2) has to be implemented. I decided to make my Y equal to one meter‚ so my calculations would be easy to get. I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know

Background Information and Research Paper chromatography uses selective adsorption on a strip of paper. It is used for separating and identifying mixtures that are or can be colored‚ especially pigments. This can also be used in secondary or primary colors in ink experiments. Is it used for Contaminants in rainwater‚ Analysis of narcotics‚ and Detection of substances in urine. Purpose • The purpose of this lab is to see the separation of dye on the candy.
