Amixer combines two inlet streams to form a single outlet stream. one inlet stream adds 10 l/min of 5 wt% magnesium phosphate in water. the outlet stream must produce 35 l/min of a 2.2 wt% magnesium phosphate solution in water. assume the density of all solutions is identical and equals 1.200 g/liter. a [5 pts) sketch this system, label all variables. note if the information is a known or unknown variable (knowns have numeric values with units) b (5 pts write out a total mass balance around the mixer c.[5 pts) write out a water mass balance around the mixer d [5 pts) write out a magnesium phosphate mass balance around the mixer e [5 pts] calculate the mass fraction (or weight %) of magnesium phosphate in the second inlet stream f.[5 pts) how might your answer change if the density was not the same for each stream? 1 inch = 2.54 cm = 25.4 mm pw = 1000 kg/m3 1 kg = 2.205 lbm = 1000 g 1 atm = 760 mmhg = 101,325 pa 1 m3 = 264.2 gallons = 10001 density [] mass/volume mw [+] molecular weight, g/g-mol gravity = 9.81 m/s

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
