Case #3 Janet is putting a lot of effort into her final science report. She has neglected the course earlier in the year and has chosen a difficult topic to impress her teacher and get a good grade. Her friend
Sarah, who is a very good student, is working on the same topic. Janet asks whether she can work cooperatively with Sarah, as permitted by her teacher. Janet then puts in little further effort, knowing she can rely on Sarah to do a good job. Since she is Janet's friend, Sarah raises no objections to having Sarah simply put her name on the report and share the grade.
1. Since Sarah does not object, what is inappropriate about Janet's action?
2. What other options are open or available to Sarah?
3. If you were Sarah, what would you have done?
4. How could the teacher change the assignment without discouraging students' cooperation, while preventing students from simply taking credit for work done by
others?

What is the name of this hydrocarbon?

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
