Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.
What is one example of systematic error that can occur in an experiment and one example of random error that can occur in an experiment?
There are three types of error in the laboratory: random error, systematic error, and gross error. Elaborate how can you use standard deviation and percent error in identifying the errors made in the measurement.
but the answer is false... so it will affect precision and accuracy? I know that this error belongs to systematic error, so systematic error affect precision?
Explain the difference between random error and systematic error.
Distinguish between accuracy and precision and between systematic and random error (§1.5) (EPs 1.57–1.59)
Give two examples of the Method error (one of the classification of systematic error). Please do not give what is already given in the example. Thank you
Which of the following represents the correct use of an internal standard (IS) in a quantitative analysis method? a) IS added to all standards and samples b) IS is added to all samples and the highest concentration standard c) IS added to all standards d) IS added to all samples
What is the difference between a decigram balance and an analytical balance?
What is the smallest mass that we can measure on an analytical balance that has a tolerance of ±0.1 mg, if the relative error must be less than 0.1%?
