Materials and ProcedureIntroduction The reason for the lab is finding the particular heat for the metals.  In the experiment, a certain liquid is heated with the metal in it then left into the water at room temperature. As changes in the heat happen to indicate that the heat from the metal can be transferred through the water hence explaining why energy is impossible of creating and destroying. A substance was heated, the motion o...

Antiviral Agent/Drug ResearchA new journal has been launched entitled: Highlights in Drug Discovery to which you have been recruited as a scientific journalist. Your remit is to write  articles on the ‘hottest’ topics in aspects of drug discovery and development. In particular, you will be asked to compete favourably with your closest rival journal:  Drug Discovery Today: http://www.d...

Assignment Brief You are a Chemical Engineer working as the Environment Manager for an innovative Scottish company, Planet Protectors Ltd. Planet Protectors Ltd wish to contribute to Scotland's transition to a more circular economy (via the biological loops in the butterfly diagram) by investing in a centralised anaerobic digestion (AD) process plant for treating organic material and converting it to renewable energyand a low-cost bio...

ObjectivesCreating engaging lessons that include activities and assessments aligned to objectives and course outcomes is one of the responsibilities of a higher education instructor. While it is not always necessary for higher education instructors to create daily lesson plans, knowing how to create a lesson plan can help prepare instructors to deliver content effectively. For this assignment, write a lesson plan based on one of the topics from ...

ObservationsOption 2: Create a polymer with the longest stretchTo test the “stretchiness” of your polymer, we will use a meter stick as well. For the test, hold one end of the putty and allow gravity to stretch the material. Measure the length of the putty before it breaks.Complete three separate stretch testsand find the average length.ObservationsIn this section, you need to includetwo things:1.Aqualitative description of your fina...

Gas Chromatography Temperature Programs and HPLC Gradient ElutionsUsing text and diagrams as appropriate, answer the following questions. This should probably take about 3-4 pages. Text has to be typed but figures can be hand drawn if necessary. Acknowledge all your sources.Submission must be as a single Word or PDF file to the MyLS Dropbox.(a) Explain what temperature programs are in gas chromatography, AND what gradient elutions are in HPLC.Wh...

Problem Set with SolutionsComplete the following assignment and post two solutions to the discussion board. Before you post your solution, read other posts to make sure you are not repeating a solution. 1. Calculate the molar mass of SF6.                         2. Calculate the molar mass of (NH4)2SO4  3. Cal...

The following problems are samples of the kinds of kinetics questions that you are likely to meet in short tests and examinations. We strongly encourage you to attempt the problems and check your answer with your tutor in the tutorial class.1.A sample of 0.6760g of an unknown compound containing barium ions (Ba2+) is dissolved in water and treated with excess of Na2SO4. Barium Sulphate (BaSO4) precipitates are formed. i.Write the balanced chemica...

Dehydrogenation of isopropyl alcohol (IPA) yields a mixture of acetone, hydrogen, and unreacted IPA. We can separate 99.50 wt% pure acetone as the main product, while IPA and hydrogen can be recycled back to the reactor. Develop and simulate a separation process to recover these products. Use COMThermo with Peng-Robinson for vapor and NRTL for liquid.Design Basis:Process Feed is 100 kgmol/h, 350 C, 300 kPa, 38 mol% H2, 38 mol% acetone, 4 mol% iso...

ObjectiveObjective:Develop and simulate a process with the least production cost ($ per tonne of acetone product, not acetone component).The lower this cost, the higher your marks for solution quality.Recover at least 95% of the acetone component in the feed.Recover 99 wt% pure water at 35 C and at least 120 kPa for use as a solvent in any absorber, if needed. Display summaries of key results and process variables in the form of various tables i...

1. You might have already recognized that DCM has relatively high solubility and a relatively high vapour pressure. What characteristics of this molecule (look at the diagram) account for its high solubility? What accounts for its volatility?   2. Let’s start at the warehouse. The pipe is 3 m below the surface. Based on the size of the warehouse, the quantity of DCM spilled, and the volume of the vadose zone (unsaturated ...
