The alloy bronze contains copper and tin. This is:

a) Homogeneous mixture

b) Heterogeneous mixture

c) Solid solution of two immiscible metals

d) Pure substance

The correct answer is: a) Homogeneous mixture

Alloys like bronze are homogeneous mixtures because they have a uniform structure and composition throughout the material.

Explanation:
Bronze is an alloy primarily made of copper (Cu) and tin (Sn). In an alloy like bronze, the two metals are mixed at the microscopic level, forming a uniform composition throughout the material. This means that every small sample of bronze contains copper and tin in the same proportion as the entire piece.

Because the components are evenly distributed and cannot be easily distinguished by visual inspection or simple mechanical separation, bronze is classified as a homogeneous mixture. Although it contains multiple elements, it is not considered a pure substance since it consists of more than one type of atom combined physically, not chemically bonded in fixed ratios like compounds.

• Heterogeneous mixture refers to mixtures where components are visibly distinct.
• Solid solution of two immiscible metals is incorrect because copper and tin are miscible when melted and form a solid solution upon cooling.

Pure substance applies to elements or compounds, not to alloys made of multiple elements.
