WebIn this experiment, students will use zinc granules react with hydrochloric acid to generate hydrogen gas (1-1). Then, use the hydrogen gas to reduce copper oxide to elemental copper upon heating (1-2). Analyze the mass content of copper in the sample, and finally determine the empirical formula of copper oxide. Zn(s) + 2HCl(aq) H 2 (g) + ZnCl 2 WebAnalysis/Conclusion: The purpose of this lab was to determine the empirical formula of a compound (magnesium oxide). In order to calculate the empirical formula, the mass of each element in the compound was determined. Then, the number of moles of each element in the sample was calculated.
WebAn empirical formula consists of the symbols of the elements combined in a compound with subscripts showing the smallest whole-number ratio between the elements of the compound. In this lab, students will determine an empirical formula from experimental data. Students will oxidize tin by treating it with nitric acid.
