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.
Brass is a homogeneous mixture because it is an alloy consisting of copper and zinc. Alloys are made from combinations of different metals. Homogeneous mixtures are uniform in their compositions.
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.

Bronze is a homogeneous mixture (alloy) of mainly copper and tin.
