I'm posting this again because the answer I got last time made no sense to me.

Peter looked on his cereal box, he saw that it read 'contains added iron.'
Peter wanted to see the iron in his food.

Peter got out a magnet, and the iron came to the top of the flakes. They were tiny pieces of black.

Why did the iron come to the top of the flakes?

I think that the iron came to the top of the flakes because when iron is attracted to a magnet they are raised up to the surface. I know that, but I need help on the force that pulled them up to the surface, and another question I was stuck on:

Why were the tiny iron pieces black?

Was it because when two elements combine they turn to black from the chemical reaction, because originally Iron the element is grey. But it didn't say a compound, so the iron is an element right? So why are the pieces black :S please help, i'm confused!!

because iron is magnetic so when he put the magnet near the iron it attracted to the magnet,black was just happened to be the color

I think the it was magnetic force that pulled them up, if I am recalling that correctly, because magnetic force is related to magnets.

Sorry, I don't know how to help you with your second question.

I hope I helped you a little!

The reason the iron came to the top of the flakes when Peter used a magnet is because iron is a ferromagnetic material. Ferromagnetic materials are attracted to magnets and can be magnetized themselves. When the magnet is brought close to the cereal flakes, the magnetic field from the magnet attracts the iron particles present in the cereal, causing them to move towards the surface of the flakes and appear on top.

Regarding the color of the tiny iron pieces, it's important to note that iron by itself is actually silvery-gray in color. However, when iron comes into contact with certain substances or undergoes certain chemical reactions, it can form compounds like iron oxide or iron sulfide. These compounds can have a black or dark color. In the context of the cereal, it's possible that the iron particles present in the flakes reacted with substances in the food during processing, leading to the formation of iron compounds that appear black.
