Interpretation: The reason for the mass of rust to be greater than the mass of powdered iron needs to be explained.
Concept Introduction: Oxidation of metal takes place when they are exposed to air or moisture. Here, the reaction of metal and oxygen takes place to form metal oxide.
Explanation of Solution
When the iron powder is left in the air or exposed to the air, it gets oxidized to form rust. This is called corrosion. In this process, a
Therefore, the mass of iron and oxygen is equal to the mass of iron rust. Since the mass of rust is the sum of masses of powdered iron and oxygen, thus, the mass of the rust is greater than the mass of powdered iron.

- Draw and show the full mechanism of how the molecule ((1E, 3E, 5E)-1-methoxyhepta-1,3,5-triene) is built using substitution and elimination reactions. You can start with an alkane of any carbon length with any number of leaving groups attached or with a alkoxide of any carbon length (conjugate base of an alcohol). Show each step and and explanation for each reaction. Also include why the reagents and solvents were picked and what other products can be expected.arrow_forwardDon't USE AIarrow_forwardDon't USE AIarrow_forward
