- Grammer Chicken produces canned chicken a la king. The chicken a la king passes through three departments: (1) Mixing, (2) Retort (sterilization), and (3) Packing. In the Mixing Department, chicken and cream are added at the beginning of the process, the mixture is partly cooked, and chopped green peppers and mushrooms are added at the end of the process. Conversion costs are incurred evenly throughout the mixing process. November data from the Mixing Department as follows: 1 Summarize the flow of physical units and compute the equivalent units. (Hint: Each direct material added at a different point in the production process requires its own equivalent-unit computation.) i. Check your spelling carefully and do not abbreviate. ii. Follow the format of the exhibit that shows the flow of physical units and output in terms of equivalent units. iii. Complete all input areas. Be sure to include any zero balances in the report. 2 Compute the cost per equivalent unit for…Wine goes bad soon after opening because the ethanol CH3CH2OH in it reacts with oxygen gas O2 from the air to form water H2O and acetic acid CH3COOH , the main ingredient of vinegar.

- Mercury poisoning is a debilitating disease that is often fatal. In the human body, mercury reacts with essential enzymes leading to irreversible inactivity of these enzymes. If the amount of mercury in a polluted lake is 0.5 μg Hg/mL, what is the total mass in kilograms of mercury in the lake? (The lake has a surface area of 100.6 mi2 and and average depth of 15 ft.)What is the physical significance of the compressibility factor Z?In a metered-dose inhaler (MDI), such as those used for asthma medication, medicine isdelivered by a compressed-gas propellant. (The device is similar in concept to a can of spraypaint.) When the inhaler is activated, a fixed amount of the medicine suspended in thepropellant is expelled from the mouthpiece and inhaled. In the past, chlorofluorocarbons(CFCs) were used as propellants; however, because of their reactivity with the Earth's ozonelayer, they have been replaced by hydrofluorocarbons (HFCs), which do not react withozone. Now HFC use is also being reduced due to their high global warming potential. In one brand of inhalers, the original CFC propellant was replaced by HFC 227ea (C3HF7,heptafluoropropane). The volume of the inhaler propellant reservoir is 1.00×102 mL, and thepropellant is charged into the reservoir to a gauge pressure of 4.443 atm at 23°C. An onlinesearch for properties of HFC 227ea yields the information that the critical temperature andpressure of the substance…
