Percent Yield Lab ReportInstructions: For this investigative phenomenon, you will need to determine the percent yield ofmagnesium oxide from the given reaction to determine if it is a useful commercial process.Record your data and calculations in the lab report below. You will submit your completedreport.Title: percent yield labObjective(s): I will react magnesium metal with the oxygen in the air by burning metal anddetermine the percent yield of magnesium oxideHypothesis:No hypothesis needed for this lab. Your theoretical yield calculation serves as your prediction forwhat you expect the lab to produce, and that will be determined later in the lab.Procedure:Access the virtual lab. Because this lab is virtual, summarize the steps used to collect your data.In addition, list and explain your controlled variables, independent variable, and dependentvariable for this lab.Materials:Percent Yield Virtual LabVariables:Remember, controlled variables are factors that remain the same throughout theexperiment. An independent (test) variable changes so that the experimenter can see theeffect on other variables. The dependent (outcome) variable will change in response tothe test variable.Controlled variables: Bunsem burnerIndependent Variable: # of magnesiumDependent Variable: the yield
Summary of Steps:Data:Type the data in the data table below. Don’t forget to record measurements with the correctnumber of significant figures. Hint: Using the same instrument, you should have the samenumber of digits to the right of the decimal.
