Errors of different varieties may arise throughout the course of an experiment. Below, match the different types of errors with their corresponding definitions. Group of answer choices Errors that have an equal chance to be positive or negative. These errors will arise because it is impossible to make any measurement completely exact. Errors that will have a consistent directional bias every time the experiment is carried out. These errors tend to always be positive or negative, meaning over or underestimating, respectively, the true value of the measurement due to experimental limitations. An error that is within the direct control and/or caused by a mistake from the chemist. Options Random error Systematic error Human mistake
A spherical object has a specific gravity of 3.46 and a radius of 1.42 cm. After this spherical object is placed into 46.4 mL of water, what should the resulting volumne (in ml) be? Type your answer... Previous Next
Why should the selected rule(s) be followed? Weighing wet items will cause the displayed mass to be greater than the actual mass of the object. A residue left on the balance will contaminate the balance pan surface and anything that comes into contact with it afterwards. Objects at any temperature other than room temperature can create air currents which can affect the balance pan, causing the measured mass to be higher or lower than the true mass. There may be discrepancies in accuracy between individual balances.

Q5: The following corn yields were collected from various acre sized plots from around Kickapoo IL: 196 bushels, 202 bushels, 192 bushels, 203 bushels, 199 bushels, 204 bushels, and 189 bushels. You checked for outliers and found none. The standard deviation for the set came out to be (s = 5.757 bushels) and the average came out to 197.857 bushels. How many bushels of corn per acre of land did the Kickapoo area produce? Are these measurements accurate and precise? Explain.
