ACTIVITY 2: Wastewater Four CornersDirection: Read the introduction and instructions given for the activity entitled Wastewater FourCorners. (Retrieved from Tumer_Ross_Chemistry_LP on September 21, 2015)IntroductionOne of the main reasons for treating wastewater is to remove the organic carbon and othernutrientsfrom the water. If these nutrient sources are not removed, when the water reaches lakes or other bodies ofwater, it will affect that body of water's ecosystem. For example, if the waste material is excess nitrogen, thisis digested by algae that causes excessive algae growth. The algae uses up oxygen from the water to growand to digest the nutrients found in the wastewater. The depletion of oxygen in the water kills other life suchas fish and other marine organisms that is dependent on it. Such will result to an alarming state that willeventually destroy marine life.InstructionIn each comer of the room there are equations involving the breakdown of wastewater material. Inevery corner, determine the amount of carbon dioxide created by the reaction specific to each corner. Afterthat, compare the results other comers. Determine which reaction produces the most carbon dioxide.Estrogen is found in many pharmaceuticals and in biologically enhanced foods.Estrogen: C18H24O2 + 23 O2-> 18CO2 + 12H2OStart with 20g Estrogen.CORNER1:Casein is a protein found in milk products and digested.C8H12N203 + 3 02- CSH7O2N + NH3 +3CO2+ H2OCSH7O2N is Bacterial CellCORNER 2:C8H12N203 is CaseinStart with 30g Casein.CORNER 3: Urea is a product found in urine.NH2COH2N + H2O + 7H- 3NH4 + CO2Turning urea to ammonium, start with 60g urea.CORNER 4: 6NO3 + 5CH3OH-> 3N2 + 5CO2 + 7H2O + 60HTurning nitrate into nitrogen gas.Start with 20 g nitrate.| ACTIVITY 3. PROBLEM SOLVINGDirection: Solve the following stoichiometry problems. Show complete solutions whennecessary.1. How many grams of sodium sulfate will be formed, if you start with 1.25 L of a 4.0 M solution of sodiumhydroxide?2 NaOHH2SO42 H20->NazSO42.
