Question

Brass is an example of
A.Homogeneous compound
B.Homogenous mixture
C.Heterogeneous mixture
D.Heterogeneous compound

Answer 1

Hint: Brass is an alloy of copper and zinc. Now just figure out what could be the answer by recalling the definition of compound and mixture.

Complete step by step answer:
Brass is an alloy made primarily of copper and zinc. The proportions of the copper and zinc are varied to yield many different kinds of brass.
Brass involves two materials that are solids at room temperature.
A mixture is formed when two or more substances are physically mixed together. A compound is formed when two or more substances are chemically combined through a chemical reaction.
An alloy is considered as a homogeneous mixture because it is a mixture of two or more metallic elements. The composition of metals remains the same in every sample of alloy.
Hence we can say that Brass is an example of Homogeneous mixture.

 The correct option is B.

Additional information: Lead is commonly added to brass at a concentration of around 2%. The lead addition improves the machinability of brass.
Brass has long been a popular material for decoration for its bright gold-like appearance, e.g. for drawer pulls and door knobs.
 It has also been widely used for all sorts of utensils due to many properties, such as low melting point, workability (both with hand tools and with modern turning and milling machines), durability, electrical and thermal conductivity.
 It is still commonly used in applications where low friction and corrosion resistance is required, such as locks, hinges, gears, bearings, ammunition casings, zippers, plumbing, hose couplings, valves, and electrical plugs and sockets.

Note: Basic modern brass is 67% copper and 33% zinc. However, the amount of copper may range from 55% to 95% by weight, with the amount of zinc varying from 5% to 45%.
