Physical Properties of Iron
1. Boils at 2750°C
2. Iron's density is 7.874g/cc
3. It is silver- white when pure
4. Its Atomic Mass is 55.847
5. It reflect 65% of the light that hits it
Chemical Properties of Iron
1. Oxidizes in damp air
2. It dissolves quickly in dilute acids
4. It corrodes fast in high temperatures
5.When iron is exposed to air it reacts with oxygen
to form hydrated ferric oxide on its surface (rust).
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
Iron is a metal and has properties of metal without being metalloid.
It is a physical change unless it is caught on fire to mold into a different shape then it would be a chemical change. The substance that does change shape does not develop new chemical properties.

The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
They are two different elements composed of two different types of atom. They have different chemical and physical properties.
Sodium iron is not a known chemical compound. However, sodium and iron separately have distinct chemical properties. Sodium is a highly reactive alkali metal, while iron is a transition metal with variable oxidation states. When combined, they can form various compounds with different properties depending on their ratio and bonding.
The formation of rust from iron and oxygen is a chemical reaction. This is because the iron reacts with oxygen in the air to form a new compound, iron oxide (rust), which has different chemical properties from the original iron.
Iron sulfide is a chemical compound formed by iron and sulfur combining. It has unique properties different from its constituent elements, such as a distinct crystal structure, color, and chemical reactivity. Iron is a metal, sulfur is a non-metal, and iron sulfide is considered a compound with its own distinct properties.
Because iron oxide is not iron and the chemical/physical properties of substances are different.
When iron rusts, it undergoes a chemical change. This is because the iron reacts with oxygen in the air to form iron oxide, which has different chemical properties compared to the original iron.
Iron keeps its unchanged chemical properties, but in a mixture it might add new, mostly physical properties to the alloy, this is also true for the other elements in the mixture, eg. C or Ni, or Cr in steel alloys.
Rusting of iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This reaction leads to the formation of a new substance with different properties from the original iron.
