Peter Mehnert Rhet 105 Ms. Paterson 11/14/12 Extended Synthesis: Cigarette Smoking Tobacco has played an important role in America from the beginning. It was grown as a cash crop by the Jamestown settlers in 1612‚ but over the years the popular opinion has changed about tobacco. Tobacco is used to make cigarettes‚ which have been extremely popular‚ now known to be extremely dangerous. Even the warnings on the cigarette box have changed to a statement much more alarming. In the 1960s‚ the warning

Starting with the weight of .198 g of salicylic acid‚ the moles of the reactant was determined to be 1.43 x 10-3‚ as shown in Equation 3. The purified aspirin product was a white powder that had a weight of .140 g. The number of moles of the purified aspirin product after extraction was 7.77 x 10-4 as shown in Equation 4. These two moles calculated a chemical yield of 54.3% as shown in Equation 5. The melting point of the pure aspirin product was ranged at 117.8-125.2C as shown in Table 1.

Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

Synthesis of Information In summary‚ the articles researched were divided into four main categories. The categories all focused on something different. The categories were; the perception kids have on food‚ communities raising healthy kids‚ nutritional awareness and the school context. The first two articles had the common theme of how children view food and to find what children thought and felt about healthy food. The third article was aimed towards parents. The theme of this article was how

Synthesis Argument Do you want to have everything decided for you? Does that make you feel safe and comfortable? How about confused and concerned? Do you see too many laws that restrict your freedom? Government protects people from threats and is not to unnecessarily legislate that restricts freedom and governs morality but to leave that to the realm of individual responsibility. Government is defined by the Webster Dictionary as "the system by which a state or community is governed." In America

It is highly sensitive to acid in the solution sate‚ enabling its wide application as pH-dependent probes. In acidic solutions‚ the ring-opened form is predominant‚ and therefore it is strongly fluorescent. Although this acid-sensitive equilibrium has been well known in solutions‚ its properties in the solid states are not well examined. Therefore‚ relative test of acid gas-sensitive property of RH-PY was proposed in this study. Figure 1. (A) Device schematic of acid-gas sensitive test‚ (B) Absorption

that their grandfather once breathed from and the land in which their great grandfather once walked on‚ the land he is now buried in. It’s hard to imagine the earth still in one piece without the devoted affection and veneration the earth waits to receive. Chief Seattle asks “If we do not own the freshness of the air and the sparkle of water‚ how can you buy them” (Seattle 2-4)? How does man dare to claim a piece of land as his own and attempt to receive profit from it? On the contrary‚ man should be

Introduction The purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound
