You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g.   QUESTION: Provide a valid and full justification as to whether you would advise your manager that the process is satisfactory when it is properly adjusted, or would you seek their approval to improve the process?

A teacher developed a new chemical - NONDISTRACTUS, which allows students to focus in the classroom more and not be distracted by random events. For NONDISTRACTUS to be effective there must be a minimum concentration in the student's body of 2.00 x10-3 mol / L. If the concentration falls below this level, the students are faced with a 10 min nonproductive period where they cannot focus on anything. NONDISTRACTUS was found to undergo a very rapid first-order decay with a half-life (t½) in the bodies of students of 23 min. Based on this information:a) What is the rate law constant, k?b) If the student starts off with an initial concentration of 2.25 x 10-2 mol / L dose, how long will it be until the concentration is above the minimum 2.00 x 10-3 mol / L? Will it ensure that they are not distracted for the entire test?

Write the balanced chemical reaction, including phase labels, for this reaction: "solid potassium chlorate reacts to form solid potassium chloride and gaseous oxygen Enter your balanced chemical reaction in a format similar to the following example format: CH(1) + 110₂(g) →7CO₂(g) + 8H₂O(g)

Since the pandemic has hit, more people are growing their own gardens and processing the fruits of their work. One thing that is flying off the shelves are spices for canning, such as alum. From this lab, you have seen how easy it is to prepare an alum, and the ingredients to make this are not difficult to obtain. You are going to make a batch of pickles and the recipe requires 6.05g of alum for each quart jar of pickles and you plan on making 50 jar of pickles. The % yield of making alum is only 84.4%.  a. What is the actual yield of alum that you need to prepare to make your pickles?  b. What is the theoretical yield of alum required to prepare the pickles?  c. What mass of aluminum do you need to start with to make the required amount of alum for the preparation of the pickles?

A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 11.10 g.L-¹. The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.30 g⋅L¯¹. Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Be sure your answer has the correct number of significant digits.

1.) In the Dumas method for determining the molar mass of an unknown volatile liquid, a sample of a volatile liquid that boils below 100 oC is vaporized in a boiling water bath and the mass of the vapor required to fill the flask is determined. The following data was collected:  Flask Volume 100.0 +100.0 + 79.6 mL = 279.6 mL Mass of Flask + Cap 143.85 g Mass of Flask + Condensed Liquid 144.95 g Mass of Condensed Liquid 1.10 g Temperature of Water Bath (oC)  84.1 oC Barometric Pressure (atm) 0.985 atm   a.) What is the molar mass of the unknown?  b.) What will its temperature be when the pressure is 1.20 atm and the volume is 250.0 mL?

An environmental study was performed to measure the transport of a DDT (a banned pesticide) throughout the globe. A lake in northern Canada was sampled to see if low levels of DDT were present there in spite of it not being administered within 1000 miles of that location.  1.000 L of the lake water was spiked with 100.0 uL of  a 2.451 ug/L solution of tetrachlorobenzene, which acted as the internal standard.  The entire 1.000 L spiked solution was concentrated onto an SPE column.  After washing the SPE column with ~5 mL of pure water, the analyte and internal standard were eluted from the SPE column using ~5 mL of CH2Cl2 solvent.  The eluted sample was evaporated under a stream of nitrogen to a final volume of 1.000 mL.  1 uL of this final solution was analyzed using GC-MS, and gave a signal of 24835 for DDT and 11597 for tetrachlorobenzene. To calculate the response factor, a standard solution was prepared consisting of  1.482 ug/L of DDT and 2.451 ug/L of tetrachlorobenzene.…

If a scientist weighs out 460.69 grams of ethanol, what is the mass of the carbon dioxide? Make sure to show the process through the dimensional analysis way. Balanced Chemical Equation • C6H5OH(1)+702(g) - ---> 6CO2(g)+3H2O(g)

A certain copper ore contains 2.32% of Cu2S by mass, and the remainder of the ore contains no copper. In a particular year, a single open-air smelt furnace heated 37000 tons of this ore. Compute the maximum mass of copper metal that could have been obtained by this process. (Clarification: The tons in this problem are English tons, with 1 ton = 2000 lb. You can answer in g, kg, or lb, but the computer does not understand tons as a unit for the answer.)
