What are two random errors and two systematic errors that could potentially occur when taking the...
Homework Answers
1. Systematic errors: These types of errors are observed due to instrumental, methodological or human mistakes that cause deviation from actual value. E.g (i): Error in the calibration of pH meter and
(ii) Error in the reading of pH meter may cause a lower reading of pH 6.90.
2. Random errors: These errors are caused due to uncontrollable flactuations in variables that affect experimental results. E.g:
(i): Decrease in pH caused due to random increase in atmosphere temperature of laboratory.
(ii):Stirring error
(iii): Liquid junction potential error.

1. When measuring the inner and outer diameters of the hollow block, what were the main sources of experimental error? Group these errors into those that are systematic and those that are random. 2. How could you improve the measurement of the block diameters? In particular, consider how to improve the accuracy of the average value of diameter and how to reduce the uncertainty in the measurement. 3. To how many significant figures can you state the volume of material...

Communication problems can often surface when barriers or “blocks” to listening occur, whereby the intended listener may be: a.) Taking a mental holiday: The person is daydreaming or focused on thoughts that have nothing to do with the current conversation. b.) Judging: The person is focused on your clothing, tone of voice, posture, or hair style and is ignoring the conversation. c.) Rehearsing: The person is busy thinking about how to respond to your comments and is ignoring what you...

Consider the following errors that could be made when running TLC. Indicate what should be done to correct the error. A two-component mixture containing 1-octene and 1, 4-dimethylbenzene gave only one spot with an Rf value of 0.95. The solvent used was acetone. A two-component mixture containing a dicarboxylic acid and tricarboxylic acid gave only one spot with an Rf value of 0.05. The solvent used was hexane. When a TLC plate was developed, the solvent front ran off the...

Dont need (a) or (b) thank you
You have a 0.025 L solution of piperazine (perhydro-1,4-diazine), a weak dibasic base. The K, values for its conjugate acid are 4.65*10 and 1.86*10-10 (in a solution with an ionic strength of zero). You would like to know the concentration of your solution and decide to titrate with HCl. You make a 0.10 M solution of the acid and use methyl orange as an indicator. You reach the endpoint after adding 54.16 mL...

1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...

Hi, please help 1)Draw two molecules that could hydrogen bond with each other. Draw and indicate the H-bond and label which is the donor and acceptor. 2) Look up the structure of the subunit of hemerythrin, an oxygen binding protein from invertebrates. It has been found that in some α-helical regions of the protein, about every third or fourth amino acid residue is a hydrophobic one. Suggest a reason for this finding, based on the structure you found. 3) Which...
