Question
I only need the answer for the 3rd part about which one explains the experimental error. Select all of them that apply
sapling learning Use the atomic weight in the periodic table to determine the equivalent weight of calcium Number Suppose you heat a sample of the metal in air to form its oxide and use the mass data to obtain a value of 18.930 for the equivalent weight. Sl nB93 or he ecutifs e and use the mass data to obtain a valiue What is the percent error for the experiment? Number Which of the following can explain the experimental error observed? The metal was not completely oxidized. The product contained an impurity. Some of the product was lost during heating.Explanation / Answer
OPTION A: The metal was not completely oxidized. [ANSWER]
OPTION B: The product contained an impurity. [ANSWER]
OPTION C is not reasonable because this is a metal, so it hardly evaporates. So it is only A and B.
