Question

Which of the following alloys contain tin? This question has multiple correct options
A. Bronze
B. Gun metal
C. German silver
D. Type metal

Answer 1

Hint: Alloy is a mixture of two or more metals. Determine the constituents of each alloy. From the alloys, select the alloys in which tin is one of the constituents.

Complete answer:
Alloy can also be formed when metals are mixed with nonmetals. The properties of alloys are different from its constituents. Usually alloys are harder than pure metals and have greater strength.
Metallic bonding is present in alloys. You can express the composition of an alloy in terms of mass percentage or atomic fractions. Substitutional alloys and interstitial alloys are two types of alloys. They differ in the arrangement of atoms in the crystal lattice.
The alloy german silver contains copper, zinc and nickel. Sometimes it also contains lead and tin. Since it has a silvery white colour, it was named as nickel silver or german silver .
The alloy bronze contains copper, tin and arsenic.
The alloy gun metal copper, tin and zinc.
The alloy type metal lead, antimony and tin.
Thus, the alloys bronze, gun metal and type metal contain tin.

Hence, the correct options are (A), (B) and (D).

Note: You can classify alloys as homogeneous alloys and heterogeneous alloys. Only one phase is present in homogenous alloys. Two or more phases are present in heterogeneous alloys. Example of heterogeneous alloys is steel.
