In any manufacturing process, reaction monitoring ensures that a chemical reaction proceeds as expected. Table 1 shows the monitoring data for the formation of chlorohexane, collected using a technique called gas chromatography. Note that the concentrations of the chlorohexane solutions are given in millimoles per litre (mmol l–1). The abbreviation mM (millimolar) is frequently used. Plot a graph of the data in Table 1. The graph should be drawn on graph paper or use fine grid if it’s drawn on Excel. Elapsed Time/Hours  Concentration of Chlorohexane/mM 0 0 2 40 4 65 6 80 8 90 10 95 12 99

1. The following data are from total and volatile solids tests on a wastewater. Calculate the total and volatile solids concentration in mg/L. Weight of empty dish = 68.942 g Weight of dish + dry solids = 69.053 g Weight of dish + ignited solids = 69.003 g Volume of wastewater sample = 100 mL

One milliliter (mL) of pure water has a mass of 1 gram (g). You add 100 mL of water and 100 mL of an organic solvent to a separatory funnel, shake, and let settle. There will be two layers of liquids. Select the one solvent listed below that will result in the water layer being the top layer. For each solvent, density (d) is given in g/ml. Toluene (d = 0.86) Tetrahydrofuran (d = 0.88) water is never the top layer Methylene chloride (d = 1.33)

We want to inform you that your performance as a tutor is being evaluated and will be reported to the administration. Additionally, there will be an online ranking system that not only assesses the overall performance of Bartleby as a website but also ranks individual tutors based on their question-and-answer accurate contributions. This ranking will be shared with management. Please ensure that your responses are of the highest quality, as multiple requests may be directed to the same person for assessment.

MBA Corp plans to use its idle building that can potentially be rented for $15,000 per annum to set up a manufacturing machinery there. The current Revenue of MBA Corp is $500,000. If the company takes up this project, its revenue is expected to increase by 30% for the next three years and then double (from the 3rd year level) for the next two years. After 5 years, the project will be scrapped and the salvage value is expected to be $80,000 The COGS are expected to remain the same at 60% of revenue. The SG&A and other operating costs will increase by $10,000. The cost of the machinery is expected to be $250,000. The machinery installation cost is expected to be $20,000. This investment will require additional inventory of $40,000 and increase the accounts payable by $20,000 The company spent $ 5000 in researching the viability of the building for machine installation. The company hires you as a financial manager to advise if they should take up this project or not. Other information:…

Hey!! For my science class I need to present a scienfic paper. I don't know how to find scienfic papers on the internet. If you could give me a quick couple to sentences explation of how to search of research papers on the web (SCIENFIC PAPERS NOT JUST ARTICLES/NEWS REPORTS) that would be serouisly help me a lot. I know this isn't your typically question, but this would seriously mean the world to me. Thanks

I'm having trouble with the major reactions to these three-could you please help me?
