Part 1. Using the data and observations in the table below, create a heating curve for hydrogen that Dr. Wong can reference during his laboratory testing. Be sure to include and label the following items in your heating curve: Create temperature and time intervals that are appropriate for the data. Don't start the temperature on the graph at 0 °C because the time intervals will be too large for the hydrogen data. Label the melting and boiling points on the curve. Label the three states and the two transition phases on the curve. Heating data: Time (Minutes)Observations0:00Hydrogen is a solid at ?263 °C. Heat is added to sample.2:43Hydrogen begins to change into a liquid at ?259 °C.6:15Temperature of the liquid begins to increase.10:36Hydrogen begins to form a gas at ?253 °C.14:01Temperature of the gas begins to increase.18:00Final temperature of hydrogen gas is ?245 °C. PART 2. Create a model of the atoms of a substance moving through the solid, liquid, and gas states. This can be a physical model using household or crafting items or a colorful diagram, illustration, or animation. You can be as creative as you want. Be sure to include and label the following items in your model: the three states of matter movement and spacing of molecules loss or gain of kinetic energy and temperature transfer of heat breaking or building of intermolecular bonds
The outline and rough draft are attached. This is for a final paper and a power point presentation. Please try your hardest and make it nice. The topic is in the outline and rough draft. Thank you! Term Paper & Presentation Guidelines The purpose of this paper is to apply biochemical principles to explain current real work issues in medicine, biology and/or nutrition. You will also be required to submit a power point presentation along with your paper. Format of the paper Font – Times New Roman Font size – 11 or 12 Pages – 3-5 pages (not including title page and reference page) Format of the presentation Font – Times New Roman Font size – please make appropriate for slide length Pages – 6-10 slides (including title and reference slide) Content of the paper and presentation Write about your current topic in molecular details. You must be specific down to the molecular details while describing your topic. You will lose points if you are only touching the general description of your topic. Some suggestions to include in your paper are: Introduction of your topic. What is the cause of your topic? What biochemical processes are involved in the cause. What research has been done? What research is currently being pursued? What is/are known and what is/are unclear about your topic? What is the current treatment? What biochemical processes are involved in the treatment? Your opinion – What do you think about your topic? Are there enough research being carried out? Is the government supporting the current research? Is the treatment plan working? What can be improved in this area?
There will be 3 worksheets that need to be filled out, completely on the documents and sent back to me. Each one has a different link you will need to go to in order to run a simulation and answers the questions on the worksheets. Worksheet #1: Creating a Buffer Solution Step 1: Go to the Chem CollectiveLinks to an external site. website and watch the video walkthrough. Step 2: Go to Virtual Lab: Creating a Buffer SolutionLinks to an external site. and play around with the simulation. Step 3: Click on the "Buffer Creation Problem" button for additional information. Step 4: Use the simulation to answer the problem below. Scenario: The stockroom contains 1M NaAc (Sodium Acetate), 1M HAc (Acetic Acid), distilled water and strong acids and bases. You need to create a buffer solution that has a pH of 4.75 such that when 1 mL of 10 M HCl is added to 100 mL of your buffer, the resulting pH is 3.75 (+/- 0.1). Question: What concentrations of HAc and NaAc do you need to create the buffer solution? Step 5: Post a response on the discussion board with your observations. Worksheet #2: Solution Dilutions (worksheet is attached below) Step 1: Download the Concentration Simulation Worksheet Download Concentration Simulation Worksheet. Step 2: Go to the concentration simulationLinks to an external site. website. Step 3: Complete the worksheet using the simulation. Step 4: Upload your completed worksheet Worksheet #3: Chemical Kinetics Step 1: Go to the Chem ReaX Virtual Lab: Chemical KineticsLinks to an external site. to access instructions and parameters. Step 2: Go to the ChemReaXLinks to an external site. website to access the lab simulation. Step 3: Run multiple simulations with parameter variations as needed to answer the questions from the ChemReaX Virtual Lab: Chemical Kinetics (step 1). Step 4: Post your results on the discussion board.
you will be creating an information brochure/pamphlet/instruction manual to be given to workers in a company and hospitals based on the optimal (perfect for that chemical reaction to take place) conditions for chemical reactions.
Discussion Instructions: Complete the pH Scale of Acid and Base Solutions and post your overall observations for each periodic trend. Comment and respond to 2 additional posts. Step 1: Download the pH Scale of Acid and Base Solutions Worksheet Download pH Scale of Acid and Base Solutions Worksheet. Step 2: Go the the pH simulationLinks to an external site..( https://phet.colorado.edu/sims/html/ph-scale/lates... ) Step 3: Complete the simulation using the procedures described on the worksheet. Part 1: pH on the Macro Scale Part 2: pH on the Micro Scale Part 3: My Solution
In this task, you will be creating a newspaper column/essay/written piece on whether it is effective to use electrochemical technologies as alternative sources of energy to prevent pollution, save money, help the environment etc. You will also talk about important issues with electrochemical technologies.

APA Research Paper Content INTRODUCTIONThe lipid panel of a blood test measures the total cholesterol in blood. This consists of the four types of lipids in blood, which include those considered as “good” and “bad” cholesterol. Besides, the body stores excess calories by creating triacylglycerols, which are stored in fat cells. The amounts of lipids in the human body are very important since researchers suggest that saturated fats and cholesterol are associated with diseases.
