Write one word problem and solution.A exemplar are included - be aware that the assignment has been changed slightly this year to include a requirement for percent yield. PS: Some trouble happened in my home, so I didn't go to many classes. And my teacher never sees the email. So I don't know the key points of the assignment. Can you try to tell me what key points that the assignment wants me to do?

I need help calculating and setting up questions 4 or 5.   thank you for your help!

I have my graph made but need to do the following but do not remember how.  "Use graph paper in lab book to plot moles S2O82- consumed versus time in seconds and fit with a line of best fit.""To determine the slope of your line do not use any of the data points from your data, use 2 points on your straight line.""Units of rate are M/s so you must calculate rate from the slope of your line (mol/s)" The first picture is the graph, using the seconds and moles from the second picture.

Instructions You are required to produce a short lab report using the information given in the accompanying document, ‘Lab report assessment_student data’. This document introduces an experiment, and also provides a set of experimental data for this experiment. You are required to use this data to perform steps 8 and 9 of the procedure. This includes calculations of a particular value, and then comparison to the true value. Consider any experimental errors when comparing calculated values and true values. Your report should be between 300 and 500 words (including all table contents and titles of tables and graphs). Your lab report should consist of three sections only: • Experimental • Results and Discussion • Conclusion You do NOT need to include an introduction section. Your experimental section should be written in appropriate lab report format, (passive voice, 3 rd person, in paragraphs). Your results and discussion section should contain the data presented in table format, and…
