Question

use the chemical reaction to answer the question. 4fe + 3o₂ → 2fe₂o₃ what happens to atoms of fe and o₂ during the reaction? (1 point) they are rearranged they gain mass they are lost. they maintain their properties.

Explanation:

In a chemical reaction, atoms are neither created nor destroyed (Law of Conservation of Mass). They are just rearranged to form new substances. In the reaction \(4Fe + 3O_{2}\to2Fe_{2}O_{3}\), the Fe and \(O_{2}\) atoms are rearranged to form \(Fe_{2}O_{3}\). Atoms do not gain mass (mass is conserved), they are not lost (again, conservation of mass), and they do not maintain their properties as they form a new compound (\(Fe_{2}O_{3}\) has different properties than Fe and \(O_{2}\)).

Answer:

They are rearranged.
