Question

caroline and andrew were examining a brass statue. caroline told andrew that the statue was made from a solution. andrew said that the statue could not be made from a solution because the brass was solid. which characteristic of the brass statue indicates that it is made from a solution?
o all samples of the brass melt at the same temperature.
o all samples of the brass are the same color throughout.
o all samples of the brass conduct electricity at the same rate.
o all samples of the brass have cu and zn atoms in a single phase.

Explanation:

A solution (in this case, a solid - solution alloy like brass) has a uniform composition throughout at the atomic level. Brass is an alloy of copper (Cu) and zinc (Zn). In a solution (alloy), the different atoms (Cu and Zn) are evenly distributed in a single phase. Electrical conductivity can vary depending on the exact composition (ratio of Cu and Zn), color can also vary slightly with composition (for example, different shades of yellow depending on the Zn content), and the melting point is a range for alloys (not a single temperature like for pure metals).

Answer:

All samples of the brass have Cu and Zn atoms in a single phase.
