Whаt is the primаry chаracteristic оf Rоle-Based Access Cоntrol (RBAC)?
Phоsphоric аcid, (H3PO4) which is оne of the аcids found in sodа, can cause osteoporosis,kidney stones, and other health problems. It is prepared when water reacts with tetraphosphorous decaoxide. I purchased a soft drink company called Matter & Pop. I was told to use 159.80 grams of tetraphosphorous decaoxide gas and 82 grams of water to produce phosphoric acid. 1. Give the chemical formula of tetraphosphorous decaoxide : ____________ 2. Write the balanced chemical equation for the reaction of tetraphosphorous decaoxide reacting with water to produce phosphoric acid. a) All components listed correctly b) proper phases listed c) Balanced correctly 3. Calculate the limiting reactant for the production of H3PO4. a) Show the calculation using water b) Show the calculation using tetraphosphorous decaoxide b) Which of the two is the limiting reagent? Briefly defend your answer. 4. How many grams of phosphoric acid could theoretically be made from the limiting reactant? 5. What would be my percent yield if I only ACTUALLY made 255 grams of phosphoric acid? a) Correctly set up showing units canceling out b) Correct answer ( 1.0 pts)- only granted if work is given c) correct answer, unit, and significant figures 6. In an economic perspective alone, would you invest in my company? Why or why not? *must show all your work to receive credit, no work=no credit even if the correct answer is given. *Must show correct unit and correct significant figures in answers where appropriate. Do not leave blank as partial credit can be earned.
