Question

Assertion: An alloy is considered as a mixture. Reason: Alloy shows the properties of its constituents and can have variable composition.

If both A and R are true but R is correct explanation of A

If both A and R are true but R is not correct explanation of A

If A is true but R is false

If both A and R are false​

Answer 1

Answer:

both A and R are true and R is the correct explanation of A

Answer 2

Both assertion and reason are true but reason is correct explanaion of assertion.

Explanation:

• An alloy is a homogenous mixture of two or more metals or non-metals or nonmetals mixed in a molten state.
• It can either be a solid solution of the elements of a single phase or a mixture of two or more metallic phases.
• Solid alloys give a single solid phase microstructure, and are therefore used where their properties are superior to those of pure component elements.

• Separation of components from alloys is not possible physically.
• An alloy is considered as a mixture because it shows the properties of its constituents as well as some improved properties and they can have variable composition.
• They are considered as mixtures because the elements that make it up are physically mixed together, but not chemically combined as in a compound and so they retain properties of its components.
