investigation into the origin of life. Miller took molecules which were believed to represent the major components of the early Earth’s atmosphere and put them into a closed system The gases they used were methane (CH4)‚ ammonia (NH3)‚ hydrogen (H2)‚ and water (H2O). Next‚ he ran a continuous electric current through the system‚ to simulate lightning storms believed to be common on the early earth. Analysis of the experiment was done by chromotography. At the end of one week‚ Miller observed

Electrolysis of water Use a U-tube with electrodes at each end‚ connected to a battery. Fill the U-tube with water. Turning on the battery‚ observe the results at each electrode. Next‚ test for hydrogen and oxygen gas produced at each end of the tube. 5. Burning magnesium Place magnesium ribbon in a clean crucible (on a clay triangle

chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane has its original hydrogen atom replaced with a halogen‚ it is now considered an alkyl halide (UC 2016). This experiment utilizes chlorine as the halogen that takes the place of the hydrogen atom. Alkyl halides are versatile‚ and with little effort

stereochemistry controlled by intramolecular interactions instead of steric factors. Despite isatin’s lack of steric requirements around its carbonyl functionality‚ its hydrazone derivatives exist only as Z-isomers because of the formation of an intramolecular hydrogen bond between de (–NH–) group of the acyclic chain and the oxygen of the isatin’s (–NHCO–)

The objective for the experiment was to perform a reduction reaction on the ketone group of camphor to the OH group on isoborneol. In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical

reduce vanillin to vanillyl alcohol. This lab report recaps the procedure and results of the lab. The chemical process studied in this lab was reduction‚ the process of reducing the number of bonds to oxygen and increasing the number of bonds to hydrogen. Other chemical processes included in the lab were recrystallization‚ melting point‚ and extraction. Procedure: Preparation of Vanillyl Alcohol 2.5 mmol of vanillin were dissolved in 2.5 mL of 1 M NaOH solution in a 25 mL Erlenmeyer flask.

years ago‚ its surface was molten. As it cooled‚ volcanoes were formed. These volcanoes released various gases. Around 4600 million years ago the Earth’s atmosphere was made up of Carbon Dioxide‚ Water Vapour‚ Nitrogen‚ Ammonia‚ Hydrogen Chloride‚ Sulphur Dioxide‚ Hydrogen and the Noble gasses. There was no oxygen at this time. Oxygen only appeared in the atmosphere around 3500 million years ago when the first simple organisms began releasing it. Most of the Earth’s atmosphere (78.08%) now is made
