Explanation & Answer
Thank you for the opportunity to help you with your question!
kinetic energy of block gets transferred as potential energy
0.5mv^2=0.5kx^2
0.5*1*8*8=0.5*12*x^2
64/12 =x^2
x=2.30 m

scientific method
Before responding to this discussion, please take the Scientific Method Tutorial and if needed review optional readings.Describe an example of how you use the scientific method in your daily life. Which observation(s) lead you to use the scientific method? State a good hypothesis, how you are testing the hypothesis (the experiment), results and conclusion. What are the control and treatment groups in your experiment? What is the dependent and independent variables in your experiment? Name at least one controlled variable.In your replies please provide suggestions for how the other students' scientific method examples can be improved. Examples: How can the hypothesis be edited to make it more specific (better)? Is a proper control group included? Are the independent, dependent and controlled variables correctly identified? How can the experimental design be improved? Also consider sharing any useful videos, tutorials or web-sites that helped you better understand the scientific method.

CHE 122 GMC Concentration Temperature and solubility of Salts Lab Report
CHE-122: Principles of Chemistry IILaboratory 1 Procedure – Concentration, Temperature and the Solubility of SaltsBackground:Solution is a homogeneous mixture of solute and solvent, solution = solute + solvent.
Figure 1. Ionic compound, NaCl salt (solute), dissolved in water (solvent) forming the solution.In this experiment we will analyze water solutions of ionic compounds, their concentration, and solubility in water.Concentration, in our case molar concentration, is the amount of solute, expressed in moles, that is divided by volume of the solution, expressed in liters. In the formula bellow, M is a molar concentration, n is a number of moles, and V is a volume of a solution.M = n/VEquation 1. Molar Concentration.Solubility provides information about amount of solute that can be completely dissolved in solvent at given temperature. It is expressed in grams of solute per 100 grams of solvent.
Figure 2 shows the typical representation of the solubility data, that is combined in the plot called temperature and solubility curve.
Figure 2: Temperature and Solubility Curve for Various Ionic Compounds in Water.This plot can tell us the mass of salt, expressed in grams, that can be dissolved in 100 grams of water at given temperature. There are three types of solutions that are described in this graph:Unsaturated solution: The solution that does not contain maximum amount of salt that can be dissolved in 100 g of water at given temperature (all the values below the graph line for analyzed salt).Saturated solution: The solution that contains maximum amount of salt that can be dissolved in 100g of water at given temperature (the values on the graph line for the analyzed salt).Supersaturated solution: The solution that contains excess of the dissolved salt than could be dissolved by the 100g of water under normal circumstances, temperature, and/or pressure (points above the curve for the analyzed salt).Temperature and solubility of ionic compounds: Temperature allows to dissolve more solute in 100 g of water, so we say that in most cases solubility of the ionic compounds increases with temperature.
There are several objectives of this lab:To enhance your ability to perform molar concentration to mass of the solute calculations.To familiarize you with the solubility curveTo improve your comprehension of the solubility.Pre-Lab Questions:Analyze Figure 2. Temperature and solubility curve for potassium nitrate, KNO3,And answer the following questions:What property is listed on x-axis?What property is listed on y-axis?2.Using graph for KNO3, in Figure 1, decide if the following solutions would be saturated or unsaturated?110g of sodium nitrate in 100g of water at 40°C?60g of sodium nitrate in 100g of water at 70°C?a. 140g of sodium nitrate in 200g of water at 60°C?3.According to the graph in Figure 1, will 50g of sodium nitrate completely dissolve in 100g of water at 50°C? Explain.Procedure:Collecting DataFrom the course home page, access the simulation environment by clicking on the Concentrationlink.1.After the simulation environment loads, set Volume for 0.1L by clicking on the bottom faucet. If necessary, you can add water by clicking on the top faucet.Select cobalt (II) nitrate, Co(NO3)2, from the "Solute” category.Gently shake saltshaker to add salt (solute) to the solvent.Keep adding until you obtain saturated solution.Record the concentration of cobalt (II) nitrate.Use Molar Concentration, M, to obtain number of moles, n, and then convert n to mass of the salt, m.Remember that the volume equals 100 mL (we can assume that the density of water is 1 g/mL so 1mL = 1g).Use n = m/MM for mass calculation, n is a number of moles, m is mass in grams, MM is molar mass in g/mol, calculated from atomic masses listed in periodic table.Record your calculations:Analyze your data and compare it with Figure 2. a solubility curves.Record your observations.Prepare complete lab report.Repeat procedure described in points 3-6 for two more salts: potassium permanganate, KMnO4, and sodium chloride, NaCl.
Solute/SaltSolution Concentration in mol/LSolution Volume in LCo(NO3)2KMnO4NaClCalculations and Data Analysis6.Using solution concentration data collected in Point 7 calculate amount of salt in grams that dissolved in 100 g water.Solute/SaltM in mol/Ln in molMM in g/molm in gSolubility in g/100g of waterCo(NO3)2KMnO4NaClNotesThis section should include notes about any observations or calculations of data collected during the lab.
Preparing Solubility Curve13.Using the following data draw the solubility graph for cobalt (II) nitrate, graph has to be included in the labreport:Temperature, °C01891Solubility, g/100g of water84.03 g98.93338.914.Use your solubility curve to obtain the temperature of your simulation. Hint: use solubility of Co(NO3)2 calculated in point 11.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.2.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?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?
