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.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
