In a student experiment, the empirical formula of a copper halide was found by adding aluminum metal to an aqueous solution of the halide, displacing copper metal. the copper metal was filtered, washed with distilled water, dried, and weighed; three separate determinations were performed. the copper halide solution contained 42.62 g of copper chloride per liter. the student recorded the following experimental data. trial volume of copper chloride solution (ml) mass of filter paper (g) mass of filter paper with copper (g) a 49.6 0.908 1.694 b 48.3 0.922 1.693 c 42.2 0.919 1.588 part a write the empirical formula of copper chloride based on the experimental data.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
