in table 3.5, why are the mass ratios of copper to chlorine not the same for compound i and compound ii? experimental error the copper changes to chlorine in compound ii there is another element not shown the two compounds are not the same

in table 3.5, why are the mass ratios of copper to chlorine not the same for compound i and compound ii? experimental error the copper changes to chlorine in compound ii there is another element not shown the two compounds are not the same

Answer

Brief Explanations:

Different compounds have different chemical compositions. The mass - ratio of elements in a compound is characteristic of that compound. Since compound I and compound II are different compounds, their mass ratios of copper to chlorine are different.

Answer:

the two compounds are not the same
