I. Introduction Fractional distillation is the separation of a mixture into its fractional parts that entails many concurrent vaporization-condensation cycles. This works because of different boiling points of individual substances. The temperature of the fractional distillation column decreases as its length increases. A higher boiling point component condenses on the column and returns to the solution whereas the lower boiling point component passes through the column and is collected in a receiver

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

Lab 5.3 SPRINGS- HOOKES LAW Group member: Submitted by: Submitted to: Class: Due: Lab 5.3 SPRINGS- HOOKES LAW Purpose: To study the characteristics of a spring. Hypothesis: With an increase in weight there will be a directly relatable increase in spring length. Additionally each spring will increase to different expected lengths. Materials: -Light spring -Dense spring -Brass spring -Masses -Ruler

It would be nearly impossible to have the transportation of vesicles without kinesin to guide it. And without the transportation of these synaptic vesicles to release their neurotransmitters‚ there would be no movement in the cell at all. This experiment is so important because vesicle transport in neurons helps to identify many neurological disorders. One such example is a research on Drosophila. Since there is only one kinesin light gene in the subject‚ the mutants in that one chain gene exhibit

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to determine

products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant. If these variables were not to be held constant than the findings of this experiment would be meaningless because there would be no way of desiring if the independent variable was the cause of the changes which were recorded In this experiment‚

CHE 317 "Simple Distillation" Interpretation of Results and the Report In addition to learning the technique of performing a distillation‚ you have had the opportunity to observe at first hand the behavior of a reasonably pure compound in the distillation process. You also measured quantities (temperatures) whose magnitudes you did not know beforehand. Title (be specific) Your Name Date Course Number (CHE 317-01) Introduction (give a brief statement about what a simple distillation is‚ what it is

For the seventh experiment we will be performing different type of test to see how different chemical react with each other. The first experiment will be a demonstration the professor will give to the class. the first experiment you will be performing will include a test tube you will add a couple drops of dilute hydrochloric. you will add this to five little pieces of zinc metal. In next experiment you will performed you will put 2 ml of 3% hydrogen peroxide solution in a test tube .you will also
