Question

1. toby wants to create a model to show how iron (fe) changes when it rusts and forms iron oxide (fe2o3). which statement explains how he should model these substances? iron is a compound and should have only one type of atom. iron oxide is a mixture and should have two different types of atoms mixed together but not chemically bonded. iron is an element and should have multiple atoms bonded together. iron oxide is a mixture and should have three different types of atoms bonded together in a specific ratio. iron is an element and should have only one type of atom. iron oxide is a compound and should have two different types of atoms bonded together in a specific ratio. iron and iron oxide are both mixtures that contain different types of elements. atoms of iron and atoms of oxygen should be mixed together and chemically bonded

Explanation:

An element consists of only one - type of atom. Iron (Fe) is an element. A compound is made up of two or more different types of atoms chemically bonded in a specific ratio. Iron oxide (Fe₂O₃) is a compound with iron and oxygen atoms bonded in a specific ratio.

Answer:

Iron is an element and should have only one type of atom. Iron oxide is a compound and should have two different types of atoms bonded together in a specific ratio.
