In this experiment‚ we used methyl benzoate from the last experiment with HNO3 and H2SO4 to synthesize methyl 3-nitrobenzoate. First we added methyl benzoate to 12 mL cooled conc. Sulfuric acid in a flask. In a separate flask‚ we made a solution of 4 mL conc. Sulfuric acid and 4 mL nitric acid and then added dropwise to the solution of methyl benzoate in an ice bath on a stir plate while maintaining the temperature of reaction between 5-15 °C. After the addition was complete we took the flask out

In nowadays ours vehicle are consume gasoline both benzene and diesel enormously‚ but recently we have new innovation of car’s engine call “hybrid”. Hybrid cars are save our energy! * Thesis statement: Hybrid cars are the best fuel economy and efficiency car in the world. II. Body Paragraph 1 (Pro1)

The knowledge of how fossil fuels produce emissions and how it effects many things on many different issues is vague depending on where you inquire the information. We will focus on a few effective and opposing issues‚ in which fossil fuel emissions have had an effect on society in the United States. These issues begin with the fetal and child developmental stages‚ pollutants‚ and global weather changes. We will explore alternative advantages versus its disadvantages in society today. Due to

The last region is from 6.95 to 7.56 (multiplet‚ 10H) represents the hydrogen atoms of the benzene rings and the hydrogen atoms of vinyllic carbons. From the integration of H NMR spectra‚ the product is assumed to be 2‚5-bis(4-methoxybenzylidene)cyclopentanone‚ which is a product of p-Anisaldehyde and cyclopentanone. The melting range was around

Developing Fuels * All gases take up the same volume under the same conditions. AT room temperature and room pressure this volume is 24 dm3. * Number of moles= volume in dm3 24 * Balanced equations can also be used to work out gas volumes. In the equations: 2Na + 2H2O 2NaOH + H2‚ where 15g of sodium is reacted‚ you can work out the volume of gas from working out the number of moles in 15g Na = 0.65 mol. Then you see that 2 mol of Na 1mol of H2‚ Thus 0.65 mol Na 0.325 mol H2. 0.325

Fracking Hydraulic fracturing‚ also known as fracking‚ is the process of removing once unattainable natural gas from shale formation deep underground. The fracking process was developed by Halliburton in the 1940s as a technique to stimulate gas well production. Vertical holes are drilled deep into the subsurface of the ground‚ and horizontal extensions are drilled at the bottom of the well at an average depth of 8000 feet. Once the holes are drilled‚ water is mixed with chemicals and

Introduction In this experiment‚ trimyristin will be isolated from the nutmeg by extraction‚ and then used to prepare myristic acid by hydrolysis. The isolation of a substance from a natural product is a common technique used nowadays. Usually‚ the isolation is a complex procedure and requires a lot of steps and preparation. For this experiment
