Detailed explanation-1: -Brass is an alloy made up of uniform composition of copper and zinc. It is a homogeneous mixture in which zinc and copper can be varied to create a range of brasses with varying properties.
Detailed explanation-2: -What Is Brass? Like copper, brass is a non-ferrous, red metal. Unlike the pure metal, however, it is a metal alloy that primarily consists of copper and zinc. Other metals-such as lead, tin, iron, aluminum, silicon, and manganese-are also added to produce more unique combinations of characteristics.
Detailed explanation-3: -Brass is Homogeneous because of the uniform compositions, like sugar solution.
Detailed explanation-4: -So, brass is an example of a homogeneous mixture.
Detailed explanation-5: -Brass and bronze are made up of varying amounts of metals, depending on how it is made. The elements are not bonded in constant ratios, much like the raisins and flakes in Raisin Bran. Therefore, brass and bronze are simply mixtures of elements. Metal mixtures are called alloys.
