The debate on the legalization of marijuana has been a longstanding issue. In the article‚ “What Science Says About Marijuana” by Philip M. Boffey‚ Boffey addresses why marijuana should be legalized. The main ideas address are that no one can die from an overdose with marijuana and that marijuana is not potent and addictive like heroin or tobacco. Although it can decrease one’s performance and cause symptoms of bronchitis‚ it does not have any major health issue and has no connection to causing cancer

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)

Acoustic Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20‚000Hz. As the cycles per second increases‚ the smaller the wavelengths become‚ therefore there is a higher frequency which will cause

Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

by Skyler Sarmento Professor Brand ENC 1101 28 September 2013 Marijuana has been around since man was created. Our founding fathers grew and smoked cannabis frequently. It wasn’t until the 1900s marijuana became a problem‚ and was looked at negatively. Legalizing marijuana would prove to aid millions in the medical field and produce billions of dollars to stimulate our economy. Marijuana was very much legal back in the day‚ it wasn’t just legal it was one of the biggest agricultural
