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…

I think they weigh the same but I do not really know how to explain it.

Think about the situation where you are investigating the relationship of study time vs. exam grade.a. Which variable would be on the x-axis (and why)?b. Which variable would be on the y-axis (and why)?c. Would you expect the slope to be positive or negative (and Why)? 2) Contrast and compare interpolation with extrapolation. Which is “safer” to use and why?3) Look up how “the best fit straight line” is constructed. The term “Least squares” should be in your explanation.4) If I plot some data and end up with a r2 of (-) 0.99, is my plot useless? Explain.

The experiment involves diluting a 16% sugar solution, prepared by dissolving 16 g of sugar in 100 mL  water.  Three different solutions are prepared by mixing the 16% sugar solution with various volumes of water.Make appropriate choices from the dropdowns.  Work from left to right.  Each answer can be calculated from numbers to the left of it in the row. The objective is to calculate the number in the right-hand most column in each row (% sugar in the solution). 16% sugar solution taken / mL water added/ mL diluted solution / mL Dilutionfactor % sugarin diluted solution 25 25                             [ Select right answer]                          ["50", "25", "100", "150"]                                        [ Select right answer]                          ["1", "0.5", "2"]                                        [ Select right answer]                          ["8", "50", "12.5", "25"]            25 8.3                             [ Select right answer]…

Question 11. THIS IS NOT FOR A GRADE! **It's a practice exam with the answer posted with it!** I just need help with the concept please explain

You are interested to know the Q10 value for mean heart rate (# of beats/10 sec) for a species of crab for the temperature interval of 25°C - 35°C. To find this value, you collect data for these six temperatures and calculate mean heart rate (# of beats/10 sec) for each temperature. Here is the data: 10°C 15°C 20°C 25°C 30°C 35°C Mean Heart Rate (# 23.67 23.89 24.33 27 35.89 37.78 beats/10 sec) What is the Q1o value for heart rate (# of beats/10 seconds) for the temperature interval of 25°C - 35°C? Round your answer to two decimal places.

In a particular trial, a student got a value for R of 0.083. Calculate the percent deviation of this result. Enter a number without the % sign. The percent deviation should be reported as a positive value.

Please answer the rest. they are very short answers. Thank you so much. final answ is enough. need 1,2,6

All the pre lab and post lab question must be answered please. So I mean all the questions not just one question but all. Thanks

15. (The following problem is an actual incident) A state pharmacy inspector came to a pharmacy to assay capsules labeled as "erythromycin 500 mg." When the inspector looked at the formulation record, erythromycin stearate 500 mg was formulated. The original Rx was written for erythromycin 500 mg. As a result, the pharmacy was fined for misbranding. How bad was the error? Determine by calculating the percent error. MWerythromycin = 733.93 g/mol MW erythromycin stearate = 1,018.4 g/mol
