Description
I need help with this problem:What is the pressure (in millimeters of mercury) inside a container of a gas connected to an open-end manometer when the level in the arm connected to the container is 348.5 mm in height higher than the level in the arm open to the atmosphere? Atmospheric pressure is 750.8 mm Hg and the density of mercury is 13.546 g/mL.

GMC Chemistry of Metals Exploring Reactivity Lab Report
Laboratory 7 Procedure : The Chemistry of Metals: Exploring ReactivityBackground:Let's consider single displacement reaction, where one element displaces another in a compound. This reaction can be summarized by the following general equation:A(s) + BC(aq) => B(s) + AC(aq)Figure 1: A is a free metal (s), BC is an ionic compound dissolved in water (aq), B is a free mental (s), and AC an ionic compound dissolved in water (aq).In this type of reaction, there is a competition between the two elements (A and B). During this single displacement, redox reaction one element loses electron (or electrons) to the other element.We can simplify the reaction by writing net ionic equation, that will show only the electron exchange between elements:A(s) + B+ (aq) => A+(aq) + B(s)Figure 2: A(s) is a free metal that is donating an electron and dissolving into the solution-forming cation A+(aq), a cation B+ (aq) is accepting an electron and converting to the free metal B(s).Above reaction occurs when free metal A(s) is more reactive then ion B+ (aq) in the solution.However, in cases where free metal A(s) is less reactive then ion B+ (aq) the reaction does not occur.There are four signs to look for, when analyzing a chemical reaction:Dramatic color changeGas evolution (formation of bubbles)Precipitate formation (formation of the solid)Temperature change
In this lab you will determine order the relative reactivity of four metals: copper, magnesium zinc and led by performing series of redox reactions.The main objective of this lab is to enhance your understanding of relative reactivity of metals.Before you start this laboratory assignment, you are encouraged to research relative reactivity series and read pages 651-653 in your Textbook. Throughout this laboratory assignment, you will be required to analyze a chemical reaction in terms of single displacement redox reaction. Be sure to record all observations and any relevant notes that you think you will need to include in your laboratory report.Take a moment to formulate and write down a hypothesis answering the question what group of metals is more reactive alkaline earth metals or transitional metals?Pre-Lab questions:1.Using your own words, explain what is a relative reactivity?What is a redox reaction?What happens to the electrons during a redox process?
Procedure:Preparing the Lab 5From the course home page, click on the Virtual Lab Tutorial link to watch the overview of using the virtual lab.From the course home page, access the lab environment by clicking on the Virtual LabAfter the lab environment loads, click ‘File’ then ‘Load an Assignment.’Select the ‘Redox’ category,Select the ‘Redox Reaction Series’ assignment.If you haven’t already done so, formulate a hypothesis what group of metals is more reactive alkaline earth metals or transitional metals? as you will need to include this in your final report.Select the ‘Solids’ tab in the stockroom. Then, select the container with ‘Cu' metal and move it to theworkbench.Transfer 5 mL of ‘magnesium nitrate’ to the empty 250 mL Erlenmeyer flask. Record its temperature.Record the temperature, and any other possible changes to the reaction mixture.After you record your data, clear the workbench, and start again for the next solution/metal combination listed in the table in the Data Table.Carefully analyze the Data collected in the Data Table.Write details justification for your selection of the order.link.5.At this point, you have prepared the laboratory for the first experiment with the require supplies to complete your experiments.Performing the Experiment7.Select the ‘Solutions’ tab in the stockroom if it is not already selected. Then, select the Erlenmeyer flask containing the ‘0.1M magnesium nitrate solution’ to move it to the workbench.9.From ‘Glassware’ select 250 Erlenmeyer flask, and 5 mL pipette.11.Transfer 1.0 g of ‘Cu’ to the 250 mL Erlenmeyer's flask containing magnesium nitrate solution.

NotesThis section should include notes about any observations or data collected during the lab.Report RequirementsThis section contains key information that must be included in your typed report.1.Define the problem in a manner that is clear and insightful.Identify the strategies and procedures used during the lab.Clear presentation of data including any tables or other figures that are relevant to understanding your stated conclusions at the end of the report. Include any relevant calculations performed during the lab.Clearly stated results and discussion of possible improvements to the procedure.Conclusive statements arguing in favor of your findings.3.Clear hypothesis statement and other potential solutions that identify any relevant contextual factors (i.e. real-world costs).Note: All reports will be graded using the rubric embedded within the course.Here are some questions to consider as you write your report:Does my problem statement make sense?Have I summarized my strategies/procedures well enough to be replicated by an outsider?Did I have a valid hypothesis at the start of the lab? Have I expressed this in my report?Do my tables and/or graphs make sense?Are my conclusions valid based on my supplied data?6.Did I thoroughly summarize my laboratory experience in a concise, factual way such that the reader can understand my processes and findings in the conclusion section alone?

PurposeThe nursing student should be able to identify seizure activity, how to educate the family and or caregiver of the pediatric patient on what to do if a seizure occurs and what medications to administer, implement safety to prevent injury and treatment of fracture. Develop education to support discharge based on assessment of data.CompetencyPrioritize nursing interventions when caring for pediatric clients with health disorders.ScenarioA 5-year-old Gabriel is a multiracial male weighing 48 lbs with an allergy to penicillin arrives in the emergency room, no cultural considerations identified. You are handed the following notes on the patient that read:He arrived in ER with his mother after falling out of bed after jerking movement activity as witnessed by his older brother while sleeping. Right-upper extremity appears with deformity. Mother and child speak English. Child has no significant medical history. Mother reports incontinent of urine during episode.Your AssessmentVital Signs: T 102.9, P 135, R 24, BP 118/60, O2 sat 100% RAGeneral Appearance: appears drowsy; face flushed, quietNeuro: oriented X3Cardiovascular: unremarkableRespiratory: lungs clearIntegumentary: very warm, dryGI/GU: abdomen normalPhysician OrdersComplete Blood Count (CBC)Complete Metabolic Panel (CMP)Urinalysis with culture and sensitivity (U/A C&S)Blood Cultures x 2X-rays kidneys,Influenza screeningAcetaminophen 15 mg/kg PO nowIbuprofen 10 mg/kg PO nowPad side railsSuction at bedside with seizure precautionsRadiographs of right armCast to right armStart PO fluids and increase as toleratedThe physician discharges Gabriel from ER to home with a diagnosis of; Right ear infection, Acute Febrile Seizure and fracture of the right ulna.Discharge orders include:Follow up with pediatrician in 7 daysFollow up with pediatric orthopedics in 7-10 daysCefuroxime 30mg/kg PO BID for 10 days not to exceed 100mg daily. What is the recommended dosage if cefuroxime is supplied as an oral suspension 125mg/5ml or 250/5ml?Acetaminophen 15 mg/kg PO Q4 hours PRN fever or pain and ibuprofen 10 mg/kg PO Q6 hours PRN fever and pain for up to 3 days.Acetaminophen is available as 160 mg/5 mL.Ibuprofen is available as 100 mg/ 5 mL.What is the amount of acetaminophen in mg and ml per dose? What is the amount of ibuprofen in mg and ml per dose?InstructionsDevelop a discharge plan with three goals listed in order of priority, prior to discharge from current orders. Provide rationale for why you listed the goals in a particular order. Also, list three nursing interventions to meet each of the goals (you should have nine interventions in total). Last, give the mother the exact dosage she will need to give the child for acetaminophen, ibuprofen, and the cefuroxime when she gets home and explain why the exact dosage is important.
