Is a salt (NaCl (aq))solution a mixture or compound and is bronze (Cu(s) + Sn(s)) a mixture or compund?

Question

i think salt solution is a mixture and bronze is a mixture. Am i right?

Answer 1

NaCl(aq) is a mixture of NaCl and H2O. NaCl itself is a compound.

Bronze is more subtle, because you have to know the phase diagram for Cu-Sn. It may be that there are regions where they form what is called a solid solution, which is a mixture. But I know of one intermetallic compound of the two, which is Cu31Sn8.

Answer 2

A salt solution is a homogeneous mixture (another name for a solution)

the Bronze is more difficult. Bronze is normally classified as an alloy, which is usually classified as an alloy. Most textbooks define an alloy as a metal solution. This is the anwer your teacher is probably looking for.
