CHEM 142 Cuyamaca College Le Chateliers Principle Lab Report
Experiment: Le Chateliers Principle
In this virtual experiment you will use a web-based online lab simulation to explore the effect of disturbing various chemical reaction systems at equilibrium. You will make observations of reactions before and after changing reaction conditions and apply your knowledge and understanding of Le Chateliers Principle to explain your observations. You will submit answers to prelab and postlab questions
Lab Instructions
Download and follow these lab instructions download. You will be directed to use a free website to complete a virtual lab experiment (Links to an external site.) that investigates Le Chatelier's Principle.
Carefully follow the lab instructions that describe how to perform the experiment and how to complete the prelab and postlab questions.
You can also consult Module 8 section on Disturbing Chemical Equilibrium for information about Le Chateliers Principle.

California State University Dissociation Reaction of Na3 Po4 in Water Lab Report
(3)For our purpose, assume that you are detecting Na3PO4 in water. Please write the dissociationreaction of Na3PO4 in water. What type of acid/base system is this:(a)strong/weak,(b)acid or base,(c)monoprotic/polyprotic? If polyprotic, how many protons?(4)Assume you transfer 50 mL of that sample and you will titrate it with 2 mmol/L standardized solutionof strong acid/base. Please propose what acid or what base you will use as titrant for this titration.Explain your decision.(5)Calculate the Equivalence volume (or volumes) and the pH at the (final) equivalence point.(6)Calculate the pH after you added 4 mL of titrant to your sample.(7)For this titration you will need an indicator. Please look at this list and choose the indicator to detectthe (final) equivalence point. Explain your choice.(7)Phosphates are used in your body to keep the pH constant at 7.4. What are the principal species ofphosphates that exist at this pH? What is the concentration of these species at pH 7.4? [hint: you willneed to use the total concentration of phosphates that you measured with random number generator](8)Human blood contains about 9 g/L of sodium chloride. Calculate the activity of phosphate in yoursample.(9)The healthy level of phosphate in blood is between 0.87 and 1.45 mmol/L and is related to thecalcium level. To measure the level of phosphate you need to bind the calcium before you start thetitration. The normal level of “free” calcium in blood is 4.4-5.2 mg/dL. Calculate how much EDTA youshould use to bind all the calcium before your phosphate titration. [Hint: your sample is still 50 mL]

BIO FP1000 Capella University Digestion Lab Report
Complete an interactive lab on the digestive system.Energy and the Human BodyAll body systems need energy to function. The body fuels cells with the nutrients and gases necessary to function properly. Our body takes in oxygen and circulates it through the bloodstream. Many chemical reactions in the body require cellular energy and need oxygen to drive these reactions. Some of these reactions are used to break down food and metabolize what we eat, which are a part of the digestive system.SHOW LESSAs Tanya ages, her metabolism decreases. The food she eats impacts the energy she needs to function. Not enough food or too much food can also impact her body functions. What can she do to get the proper nutrients but not gain weight? Let us take a closer look at the digestive and respiratory systems to learn about how they function in Tanya’s body and how Tanya gets energy.The body needs energy to live. The digestive and respiratory systems work to provide this energy with nutrients and oxygen. We eat food to provide energy to our cells. The digestive system breaks the food down into smaller macromolecules that the cells can process for energy. In order for the cells to utilize the nutrients, oxygen from the respiratory system is needed. The respiratory system takes in oxygen from the air and helps to expel the carbon dioxide we generate.Competency MapCHECK YOUR PROGRESSUse this online tool to track your performance and progress through your course.Toggle DrawerResourcesView the Human Body Systems Organization infographic by selecting a system to learn how these two systems work.Watch the Digestion presentation on the human digestive system that focuses on the gut, mouth, pharynx, esophagus, epiglottis, small intestine, pancreas, gallbladder, liver, and large intestine.Complete the interactive media activity to learn more about the digestive system for your assessment, Digestive System.You may also want to read the following:Lusk, J. (2019). Consumer beliefs about healthy foods and diets. PLoS One, 14(10).Ireland, K. A. (2018). Visualizing human biology (5th ed.). John Wiley and Sons. Available in the courseroom via the VitalSource Bookshelf linkChapter 14, "The Respiratory System: Movement to Air." In this chapter, you will learn more about the air we breathe. How often do you take a breath? Do you ever think about breathing?Chapter 15, "Nutrition: You Are What You Eat." In this chapter, you will learn how the digestive system breaks down these molecules into usable units of energy. "You are what you eat," is a popular phrase. But it is true?Chapter 16, "The Digestive System." In this chapter, you will learn more about the process of digestion. We eat three to five pounds of food each day to provide us with energy.Assessment InstructionsOverviewIn this lab, you will be looking at food labels. Food labels provide important information about the nutrient content of packaged food. You will analyze a food label from your own kitchen and discuss whether the food item is a healthy choice. Try to find a food item you eat often to see whether or not this is a healthy choice.Digestion Lab.InstructionsFor this assessment, you will complete a series of responses within the lab, complete an assessment at the end of the lab, and write a brief summary of your conclusion about the lab. To complete this assessment:Fill out the items requested in the lab.Complete the assessment at the end of the lab.Save a pdf of your responses and download it to your computer. You will have an option to download a pdf within the lab.Write a one-paragraph summary detailing new knowledge acquired in the lab.Attach both documents when submitting the assessment.Make sure that you read the Homework: Digestion Lab Scoring Guide prior to submitting your assessments to ensure you have met all of the expectations for this assessment.It is recommended that you review the scoring guide prior to completing the la as most work will be completed within the lab.Assessment Requirements Your summary should meet the following requirements:Length: Submit one double-spaced page.Written communication: Ensure written communication is free of errors that detract from the overall message.Standard formatting: Include one-inch margins, appropriate headers, and a title page.Font and font size: Use Times New Roman, 12-point font.Note: If you use assistive technology or any alternative communication methods to participate in this activity, please contact DisabilityServices@Capella.edu with any access-related questions or to request accommodations. Competencies MeasuredBy successfully completing this assignment, you will demonstrate your proficiency in the following course competencies and assessment criteria:Competency 2: Apply concepts of human biology to the social sciences. Estimate daily caloric need.Calculate percentage of daily calories of the food item.List serving size and calories in a serving, and calories from fats.List the sodium content, carbohydrates, sugar, protein, vitamins, and minerals found in the food item.Analyze the food item based on label.Analyze if packaging is misleading.
