Question

two different ionic compounds each contain only copper and chlorine. both compounds are powders, one white and one brown. an elemental analysis is performed on each powder. which of the following questions about the compounds is most likely to be answered by the results of the analysis? a what is the density of each pure compound? b what is the formula unit of each compound? c what is the chemical reactivity of each compound? d which of the two compounds is more soluble in water?

Explanation:

Elemental analysis determines the relative amounts of elements in a compound. From these amounts, the formula unit (empirical formula showing the simplest - whole - number ratio of atoms) can be calculated. Density, chemical reactivity, and water - solubility are not directly determined by elemental analysis.

Answer:

B. What is the formula unit of each compound?
