An iron alloy
(Explanation): Iron metal is a pure substance, so it cannot be a solution, so it's not that one. An iron ore is found in nature and is iron chemically combined with other substances, so it's not a mixture because mixtures aren't chemically combined. Iron rust is also chemically combined iron with oxygen, so it's not a mixure. Therefore, the iron alloy is the correct answer
(btw, an alloy is where you heat the metal to a liquid and mix in other metals like zinc to make pennies and stuff)
A metal alloy mixture of two or more metals and a solution is a mixture of two or more substances so they are the same.
An alloy
these are called alloys steel is an alloy of iron, carbon, and other substances to give it specific properties. bronze and brass are alloys of copper and tin or copper and zinc.
an alloy is a solid solution and a solution usually refers to solid or gas
A solution of two or more metals is called an alloy.
A metal solution for an alloy could be a complete or partial solid solution.
An alloy may be a solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions.
This is an alloy. As tgere are different sorts of alloys its best to call it a solid solution alloy to distinguish it from mixtures of different phases which are found in steel for example.
