Which of the following is an example of a homogeneous mixture?
a. bronze
b. sand
c. copper
d. zinc

Homogeneous (in terms of Chemistry) means "in the same physical state"

For example if Nitrogen and Hydrogen reacted, and they were both gases, the reaction would be homogeneous.

Sand is a compound, so therefore not a mixture.

Copper and Zinc are both elements, so again, not a mixture.

Bronze is an alloy, a mixture of Copper and Tin. As Copper and Tin are both solid (metals), we can say this mixture is homogeneous.

The answer is (A) Bronze.

The correct name for n3-ion should be azide.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
