Read the following passage.

the cathode ray experiment indicated the existence of negatively charged particles in an atom. this experiment also disproved the part of dalton's atomic model that claimed indivisibility of the atom. when the experiment was repeated using cathodes made of a different metal, each time the results were consistent. these discoveries of thompson were later substantiated by robert millikan when he calculated the charge on an electron.

use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
