Fill in the reaction table below. Make sure you correctly calculate the molar amounts of your reactants. name formula mol.-eq. Mw mmol amount p-Nitroaniline 1.0 350 mg 3 mL HCI (6M) Sodium nitrite (NaNO2) 2-Naphthol 190 mg 320 mg Sodium Hydroxide (2.5 M) 15 mL product
2) Calculate the Theoretical Yield of your product, i. e. the mass you would expect to recover (assuming 100% conversion to product). Safety and Preparedness (3 pts): The Material Safety Data Sheets (MSDS) for all the chemicals involved in this lab are on iLearn. Read these and answer the following questions:
1) Some nitroanilines are known to be carcinogens. Give one example of a precaution you will use when handling your product.
2) Both the diazonium salt intermediate and your azo dye product are hazardous, for different reasons. What are the risks associated with diazonium salts and azo dyes? What precautions will you take?

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
