While ethanol (CH,CH,OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene (CH,CH,) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 125 L tank with 33. mol of ethylene gas and 13. mol of water vapor. When the mixture has come to equilibrium she determines that it contains 24.6 mol of ethylene gas and 4.6 mol of water vapor. The engineer then adds another 17. mol of ethylene, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits. do mol

Ammonia (Hydrogen Nitride) is harmful to our cells (no duh right?) but our body naturally makes a little bit of this chemical through its natural processes. In order to get rid of this poisonous substance, our cells secrete ammonia into the blood stream to be combined with carbon dioxide. In this process, urea (CN2OH4) and water is made. Urea is less toxic to our bodies and is secreted into our urine. If a total of 32.54g of ammonia is secreted into the blood stream and 61.48g of urea is secreted in our urine, what is the percent yield of this reaction?
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200.mL sample of groundwater known to be contaminated with iron(III) chloride, which would react with silver nitrate solution like this: FeCl3 (aq) + 3AgNO3 (aq) →3AgCl (s) + (FeNO3)3 (aq) The chemist adds 48.0mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 7.5mg of silver chloride. Calculate the concentration of iron(III) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits.

20. The Haber-Bosch process, devised in the early 20th century, revolutionized global industry. It provides a way of“fixing” atmospheric nitrogen into ammonia, allowing for the production of fertilizers and the many nitrogenbased chemicals we use today.
