Ammonia must be eliminated from wastewater before it can be reused, recycled, or discharged. Describe the three major steps that are used to convert harmful ammonia into a harmless derivative. Your answer must be specific and include any appropriate chemical formulas or names of chemical or biological reagents. Mention, when appropriate, the toxicity of any of the components or how their production can get in the way of efficiently eliminating ammonia from wastewater.

Write an equation for the chemical reaction you performed in this lab. Use complete structural formulas for all chemicals. Include the catalyst, written above the reaction arrow. Synthesis of Amyl acetate Isopentyl Alcohol (CH3)2CHCH2CH2OH Glacial Acetic Acid  CH3COOH Concentrated Sulfuric Acid  H2SO4     Synthesis of Methyl Salicylate Salicylic Acid C7H6O3 Methyl Alcohol CH3OH Concentrated Sulfuric Acid  H2SO4

Based on a grade 11 chemistry student, answer the following question based on the provided tables: Part G:  Final Identification of the Poison By this time, Tylenol has been pulled off the shelves at all of the stores in the area and a nationwide recall has been announced.  Several suspicious capsules have been found and tested.   The contents of the capsules contain a compound with a nitrogen content of greater than 15% and a carbon content of less than 50%.   What is the poison in the capsule?  Provide calculations to support your answer.

Can you help me answer this type of question from my study review package please

Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?

Include the balanced chemical equation for the reaction being studied or conducted (reactants to products). indicate actual chemical structures that pertain to the experiment and indicate conditions as well as solvents over and under the reaction arrow.

Describe the toxicological effects of toxic compounds in humans and safety precautions.

21. Consider a small lake, 0.4 mile across and 11 ft deep, that contains a total of 50 tons of dissolved oxygen. Calculate the BOD (i.e., calculate the amount of oxygen required to degrade the amount of organic waste given) if 6 tons of carbon-based waste is dumped into the lake.
