Neither. Copper is not a mixture at all. It is a pure element.
A mixture of gold and copper in a coin is considered a homogeneous mixture because the two metals are evenly distributed throughout the coin and cannot be easily separated.
Brass is a homogeneous mixture because it is a solid solution of copper and zinc. Both elements are uniformly distributed at a microscopic level within the brass, resulting in a consistent composition throughout the material.
18 karat gold is a homogeneous mixture. It consists of 75% gold and 25% other metals, such as copper and silver, which are uniformly distributed throughout the gold.
No, sterling silver is not a heterogeneous mixture. It is a homogeneous mixture made up of 92.5% silver and 7.5% other metals such as copper.
Bronze is considered a homogeneous mixture because it is a uniform alloy composed of copper and tin atoms dispersed throughout the material. This results in consistent properties and composition throughout the material.
No, brass is not a heterogeneous mixture. It is a homogeneous mixture composed of copper and zinc.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
