Steel is a mixture composed primarily of iron and carbon, along with other elements like manganese, chromium, and nickel. Therefore, it is classified as a mixture, specifically an alloy.
Stainless steel is a mixture of different elements, primarily iron, carbon, and chromium. It is not a pure substance because it contains multiple components in varying proportions.
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
Steel is considered impure as it is an alloy made up of iron and various other elements such as carbon, manganese, and silicon. The impurities in steel can affect its properties and performance in different applications.
Iron is an element, so it is a pure substance.

Iron is a pure substance. It's an element (Fe) and a bar of Iron is no mixture. If it was pure iron, then by definition it would be pure. However iron is rarely pure, it is usually in alloy with something.
The pure substances from the options provided are a rod of steel, a cube of sugar, and a block of wood. Steel and sugar are pure chemical compounds, while wood is a homogeneous mixture of different compounds but is considered a pure substance in the context of the question. Leather and milk are mixtures of various compounds and are not pure substances.
pure substance, propanone

Methane is a pure substance.
iron is a pure substance. A pure substance is any form of matter that has a uniform composition and cannot be separated by physical methods such as filtration. A mixture can be separated into its components by physical means. <<>> Most nails are made from mild steel so they contain a small amount of carbon around 0.2%
