Iron reacts with oxygen to form iron oxide (rust). whichof the statements below best describes this statement? a. iron oxide is the liquid state of iron. b. iron oxide is the gaseous state of iron. c. iron oxide is formed by rearranging atoms. d. iron oxide is made up of only iron atoms.

Option (C) is the correct answer.

Explanation:

When iron reacts with oxygen in the presence of moisture then it results in the formation of iron(III) oxide. The equation for this reaction is as follows.

This , is known as rest and it is a red color oxide. Rusting of iron is a redox reaction in which atoms of iron and oxygen rearrange with each other.

Therefore, we can conclude that iron oxide is formed by rearranging atoms.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
