Question

Among the following, bronze is a/an example of:
A. An element
B. A mixture
C. A compound
D. All of these

Answer 1

Hint: We know that an alloy is a homogeneous mixture of two or more metals or a metal and small amount of non-metals. It is also known that alloy is prepared by mixing the various metals in molten state in required proportions and then cooling their mixture to the room temperature.

Complete step by step answer:
We can say that the compounds are homogeneous but mixtures may be homogeneous or heterogeneous. Therefore we can say that, this point cannot be used to decide between a mixture and a compound.
We know that properties of an alloy are different from the properties of the constituent metals. It is known that brass is an alloy of copper and tin. It contains 90% copper and 10% tin. Bronze is very tough and highly resistant to corrosion. It is used for making statues, coins, medals, cooking utensils and ship’s propellers.

Therefore, the correct option is option (B).

Note:
We know that the electrical conductivity of an alloy is less than that of pure metals. For example, brass is an alloy of copper and zinc and bronze is an alloy of copper and tin are not good conductors of electricity but pure copper is an excellent conductor of electricity and is used for making electrical circuits.
