Procedure Access the virtual lab and complete the experiments. Part One (Flame Test): 1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame: Barium-green Calcium-red Sodium-yellow Rubidium-purple Potassium-blue Lithium-pink 2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.: Unknown 1-yellow. I think it is Sodium because

Distillation Objective: To illustrate the use of distillation for separating a mixture of two volatile liquids with different boiling points. Background: Distillation consists of heating a liquid until it vaporizes‚ and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points‚ or that have one component that does not distill. There are many types of distillation‚ each of which has a distinct

Ellen Grant Honors Bio I Organic Compounds Problems and Objectives: The purpose of this lab was to select the suitable test for an organic molecule and define the safe process for that test. An organic molecule is normally found in or produced by living systems. (Unknown Author‚ 2014‚ www.biology-online.org/organic_molecule)In this lab one was supposed to infer the results of the test and be able to identify if major biomolecules are present. You were to analyze a variety of tests including

Abstract: Protecting biological diversity is defined based on analyzing the cladistic information. In this lab the null hypothesis was examined through interpreting constructed cladograms. A cladogram of five mammalian species include domestic dog (canis familiaris)‚ the Virginia opossum (Didelphis virginiana)‚ the domestic horse (Equus caballus)‚ the domestic cat (Felis cattus) and the white-tailed deer (Odocoileus virginianusis is generated based on the morphological feathers of these mammalian

Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate had accumulated within the Hickman Still Head. Smaller volumes were

One major observation made throughout this experiment was during the steam distillation. As the steam distillation started and the solution in the flask began heating‚ it was clear that too much stopcock grease was used around the glassware. The grease from the connecting ends of the three way connecting tube was melting and seeping into the clove and water solution in the two necked round bottom flask. The solution in the flask was immediately discarded and repeated with clean glassware and a very
