Question

Alloys are homogeneous mixtures of two or more elements. The elements could be two metals or a metal and a nonmetal.
If true enter 1, else enter 0

Answer 1

Hint: Basically, an alloy is a substance which is formed from the combination of two or more metals. They can also be formed from combinations of metals and other elements. Moreover, the properties exhibited by alloys are often quite different from the properties of its individual components.

Complete step by step answer:
An alloy is a material which is composed of two or more metals or a metal and a nonmetal. Further, it may be a solid solution of the elements of single phase or a mixture of two or more metallic phases. These are used where their properties are superior to those of pure component elements. The term intermetallic compound is used to refer to alloys that have well defined crystal structure and stoichiometry. Now, let’s discuss some of the examples of alloys.
A.Steel- It is an alloy that is extremely popular due to its low cost and high tensile strength. It is primarily an alloy of iron and carbon. The composition of steel is primarily accounted for by iron which is usually $75\% $ of the alloy’s weight. It can also contain varying amounts of carbon and other elements based on the type of steel. So, for example the composition of stainless steel is:
a)Less than $1.2\% $ carbon
b)Approximately $85 - 88\% $ iron
c)At least $10.5\% $ chromium
B.Bronze- It is an alloy of copper and tin. It is widely used in coins, trophies, tools and some form of electrical hardware. The composition of bronze is:
a)Tin –up to $12\% $
b)Copper $75\% $

Hence, the statement is true.

Note: Alloys can be classified on the basis of the total number of phases present. For example, homogeneous alloys feature only one phase and heterogeneous alloys feature two or more phases. Moreover, the elements that are commonly used for alloying are chromium, vanadium, Nickel, Molybdenum etc.
