(a)
Interpretation:
Whether the given error is systematic or random has to be stated.
Concept Introduction:
Systematic error:
These error occur due to instrumental flaws or due to errors in experimental design. These errors can be replicated. It can be detected and corrected. These errors are otherwise called as determinate errors.
Random error:
Random errors are uncontrollable, unpredictable and are completely random. These errors are not reproducible. These are caused due to instrumental changes or due to the change in the measuring environment. Random errors has an equal chance of being positive and negative. These errors are otherwise called as indeterminate errors.
To state: Whether the given error is systematic or random

Quantitative Chemical Analysis
- Give the structure(s) of the product(s) for the reactions below, and be sure to indicate any relative stereochemistry (you can assume that each of the Diels-Alder reactions will proceed with endo selectivity). Draw out relevant enantiomer(s) if they are expected to form. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. If more than one product is formed, please indicate which one will be the major product or if they will be formed in equal amounts. In all cases, equimolar amounts of both components/reagents are present unless indicated otherwise .arrow_forwardCalculate the residence time of strontium (Sr2+) in the world ocean, given that the average concentration of strontium in the world’s rivers is approximately 0.87 µmol L-1 (5 pts).arrow_forwardA package contains 1.33lbs of ground round.
