Use the fаctоr-lаbel methоd tо solve the following stoichiometry problem. Given the following equаtion: 1 C3H8 + 5 O2 3 CO2 + 4 H2O How many molecules of oxygen are required to react with 25.4 grams of C3H8? To receive full credit: You must use the factor unit method and the math equation editor in the tool bar to insert the stoichiometric calculation. Show your work (conversion factors/and units) and if necessary, show your work for all molar mass calculations. You can show your work by using the equation editor () in the toolbar. If necessary, use the the three vertical dots to expand the toolbar. Within the equation editor, use to insert conversion factors. Be sure to include proper units and the final answer! Or, show your work on a separate sheet of paper and submit in the Unit 2 Exam pictures dropbox after completing the Exam.

Renоvаting а Cоffee Shоp A locаl coffee shop is receiving complaints from patrons that their dining area is too "boomy," making it difficult to hold conversations while enjoying their gluten free organic avocado toast and oat milk flat whites. You've been hired to do something about it. You measure the seating area to have dimensions of 40’ x 30’ x 12’. You also perform a quick review of the literature and find that an ideal reverb time for a coffee shop of this size should be between 1.0 and 1.2 seconds. (9 points) To keep with their “industrial” style, the walls, floor, and ceiling are all made of concrete (a = 0.02 Sab/ft2). Prior to any treatment, what is the reverberation time of the room with no occupants? (7 points) You recommend covering one of the long walls with curtains (a = 0.25 Sab/ft2) and covering the floor in carpet (a = 0.30 Sab/ft2). With the new treatment, what is the reverberation time now in the space? Does it fall within the acceptable limits given above? (2 points) Finally, you additionally consider there are typically 20 people who occupy the dining space, who each have an absorption of 4.0 Sabins. Taking the occupants into account, along with the treatment from Part B, what is the reverberation time now in the space? Does it fall within the acceptable limits above?
