I am not asking for help in writing this report.  Could you solve the calculation parts for the steps on the last page? like 13, 14, 15, 17, 18, and 19. This experiment is based on this video: https://www.youtube.com/watch?v=SVvGtcFhdls

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

2 W S Type your answer to the following: Consider the steps the student took in the following scenario. Then describe anything the student did wrong and how it would have affected the student results (too high, low, or unchanged) and why. X A student forgot to weigh the filter paper prior to filtering the salt from the sand. To make up for this, the student weighed a different filter paper from the box and used that mass in the calculations.

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.

Scientific methods Instruction: Clearly provide the statement for each step of the scientific method in 1 sentence: 1. 2. 4. Problem 3. Hypothesis Experiment Conclusion 5. Data Course code: CHEM 141 SCENARIO 5: Study Habits and Test Performance A group of students in a class notice that their test scores vary, even though they study similar amounts. They want to determine if different study habits affect test performance. The students note down the study hours of each student and their corresponding test scores. They also survey students about their study methods, such as reading notes, practicing problems, or group study. The students speculate that students who engage in active study methods, such as practicing problems, will perform better on tests compared to those who passively review notes. They begin by…

Categorize each as a determinate or an indeterminate error and further classify determinate errors as instrumental, method or personal. a) An unknown sample being weighed is hygroscopic. b) One component of a mixture being analyzed quantitatively by GC reacts with the column packing. c) A radioactive sample being counted repeatedly without any change in condition yields a slightly different count at each trial. d) The tip of the pipet used in the analysis is broken. e) In measuring the same peak heights of a chromatogram, two technician each report different heights.

4. Now that you know how to take measurements from the video, it's time to determine the trial you will use for your calculations.   Pick your first trial based on your birth month: Trial 1: January, February, or March Trial 2: April, May, or June Trial 3: July, August, or September Trial 4: October, November, or December   Which is the first trial you will observe?
