Question

Assertion: Amalgam is an alloy.
Reason: An amalgam is a substance formed by the reaction of mercury with another metal.
A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C. Assertion is correct but Reason is incorrect
D. Both Assertion and Reason are incorrect

Answer 1

Hint : To answer the above question, we need to understand what an alloy is. We also need information about amalgam alloy and what are its components. Alloys are a mixture of elements that showcase selective properties of their components.

Complete Step By Step Answer:
An alloy is a combination of metals, or a metal combined with one or more other elements. For example, the alloy red gold is produced by combining the metallic elements gold and copper, white gold is formed by combining gold and silver, and silver combined with copper produces sterling silver.
Amalgam is the alloy which contains the mixture of mercury with some other metals. These metals may include any metal, with iron being the exception. In dentistry, silver-mercury amalgams are used frequently. Gold-mercury amalgams are used in the extraction of gold from its ore.
So, the correct option is (A).

Note :
Alloys have a wide range of uses in all fields including industry, medical and extraction. Alloys exhibit the properties of both of its components. So, they can be created selectively with the desired components. However, the properties of combination also matter.
