What are replicates in Analytical Chemistry? O The component of a sample that repeats over different assays. Similar assays done to different samples A sample that contains exactly the same amount of analytes than the original sample similar samples that are analyzed at the same time and in the same way

FINAL Experiment 1- January 2021_-789644623 - Saved Layout Review View Table A friend of yours went panning for gold last weekend and found a nugget that appears to be gold. With your newfound scientific prowess, you set out to determine if it is really gold. Your tests show that the nugget has a mass of 7.6 g. Immersing the nugget in water raised the volume from 7.22 mL to 8.06 mL. The density of gold is 19.32 g/cm3. What will you tell your friend? acer

How do I solve for the percent value? The sample data calculated the answers but I have no idea how they obtained the percent error values. Calculate sample data #1 with detailed steps.

2 In your one semester being enrolled in the subject Analytical Chemistry II, write your major take aways that you will never forget and explain why? For the purposes of improvement in terms of course delivery and curriculum, what changes do you wish to suggest? Finally, as a reflection, in a scale of 1-10 (1 being the lowest and 10 being the highest) how do you rate your performance in this subject.

The following volumes of 0.000300 M SCN are diluted to 15.00 mL. Determine the concentration of SCN in each sample after dilution. These values will be used during the experiment. To enter exponential values, use the format 1.0e-5. Sample 0.000300 M SCN (mL) [SCN'] (M) 1 1.50 3.50 7.00 4 10.00 3.

Explain your rationale for using the summative assessment (below) from the lesson plan on mixing substances in a 5th-grade classroom based on the below standard and learning objective, including how it aligns with the learning objective.  Summative Assessment  Summative: Components of the Lab Report Purpose: The student should clearly state the purpose of the experiment, which is to determine whether the mixing of two or more substances results in new substances. Procedure: The student should describe the steps they took to conduct the experiment. This includes the substances they chose to mix and the safety equipment they used. Observations: The student should record any observable changes that occurred when the substances were mixed. This could include a color change, the formation of a precipitate, or a change in temperature. Conclusion: The student should state whether a new substance was formed based on their observations. They should also reflect on their accuracy in…

New employees at Avondale Industries’ unmanned systems production line in Denver, CO, participate in employee training under the direction of the training and development department, but the line managers conduct the actual training. During the last two trainings, the line managers cut the sessions short and explained that the employees would receive better training while working on the production line. The trainer responsible for the program understood the line managers’ viewpoint about developing skills used on the line but needed them to see that training should provide more than just developing those specific skills. Which of the follow statements best explains why training should provide a longer-term view than just teaching line workers the skills needed to perform satisfactorily in their current jobs?     Giving line workers expanded training helps them understand more than specific skills; it also helps them become more confident contributors.   Training with a…

Discuss the language demands included in the lesson on mixing substances in a 5th-grade classroom by Identifying key vocabulary terms students must know in order to master the learning objectives for the lesson based on the below standard and learning objective. Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.

After collecting all of the class data in Part IV Table E, graph mass in grams of regular cola on the y axis in and the volume of regular cola on the x axis in mL. On a separate piece of graph paper, prepare another graph using of the same type using diet cola. What is the slope of the best fit line on each graph? What does the slope represent?

Based on this. What was the percentage error in the percentage of water in the sample, compared to pure MgSO4•7H2O?

Current Attempt in Progress From the curves shown in Animated Figure and using the following Equation, determine the rate of recrystallization for pure copper at the several temperatures. Make a plot of In(rate) versus the reciprocal of temperature (in K-1). (a) Determine the activation energy for this recrystallization process. (See Section FACTORS THAT INFLUENCE DIFFUSION.) (b) By extrapolation, estimate the length of time required for 50% recrystallization at room temperature, 20°C (293 K). (a) i kJ/mol (b) i days
