Question

An alloy is

• A. an element
• B. a compound
• C. a homogeneous mixture
• D. a heterogeneous mixture

Answer 1

The correct option is C

a homogeneous mixture

The explanation for the correct option

(C)a homogeneous mixture

Alloys

• An alloy is a homogeneous mixture of two or more metals, or a metal and a non-metal.
• properties of metals can be enhanced by the addition of certain metals or elements.
• An example of an alloy is brass.
• Brass is an alloy of $66\%$ copper and $34\%$zinc.

The explanation for incorrect option

Elements

• A basic form of matter that cannot be broken down into simpler substances through a chemical reaction is defined as elements.
• Examples of elements are gold$\left(\mathrm{Au}\right)$, silver$\left(\mathrm{Ag}\right)$, and iron$\left(\mathrm{Fe}\right)$.

Compounds

• A compound is a substance made up of two or more elements that have been chemically mixed in a certain proportion.
• Examples of compounds are Baking soda$\left({\mathrm{NaHCO}}_3\right)$, Ammonia$\left({\mathrm{NH}}_3\right)$.

Heterogeneous mixture

• Mixtures in two or more phases are heterogeneous mixtures.
• Examples of heterogeneous mixtures are salt and oil.

Hence, options (A), (B), and (D) are incorrect.

Hence, option (C) is correct. An alloy is a homogeneous mixture.
