Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts

How the Attacks on September 11th Changed the World In order for a country to fight crime there must first be crime‚ which there always is‚ but specifically there must be enough of a certain kind. My topic is terrorism as this recently changed the face of America and created multiple government agencies and plans for action. Other examples are the drug trade‚ human trafficking‚ and gun running. September 11th‚ 2001 marks the day that most of were alive for and remember well. America was rocked

Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction

ENG 107 Story of an Hour Extract: “When the doctors came they said she died of heart disease–of joy that kills.” Write a persuasive essay of between 500 – 700 words in response to the following question: Early in the story we learn that Mrs. Mallard is “afflicted with heart trouble‚” though her unexpected reaction to her husband’s death may suggest and alternative reason for her poor health. What was the cause of Mrs. Mallard’s death? Explain your point of view. “A joy that kills”‚ not exactly

Lab #5: Grignard Reaction – Synthesis of Triphenylmethanol John Kang Chem 152L Performed: 7/20/04 Date submitted: ________________ Lab Partners: Sang Lee‚ Vicky Lai TA: John Stanko Abstract: This experiment explored the synthesis of triphenylmethanol through the use of Grignard reagents. The percent yield of the product was 10% on a relatively humid day. The melting point was calculate to be 127.2oC with a literature value of 162oC. An IR spectrum of the product was taken and used

“The Story of an Hour” reflection‚ I find myself lumped together with the group of women that can feel compassion and sympathy for Mrs. Mallard’s situation. I do not think that she was cold or cruel in her reaction to the news of her husband’s death. In my opinion‚ Mrs. Mallard’s reactions were primal‚ completely genuine and justifiable. There are many pressures that people experience due to societal expectations and our own expectations of life and romance. There is no way to know that a commitment
