Why is rust mainly found at the edge of a rust spot and not in its center?

Balance the reaction equation?
Hi, I really don't know much about chemistry, but can someone explain to me how to balance a reaction equation? Thanks in advance.
4:2:1?
What do I need to add to 4 parts water, 2 parts vinegar, and 1 part detergent?
Why the dome model?
Why is the C atom shown larger than the O atoms in the space-filling model, even though the latter has a smaller radius? LG
Verification of Hess's theorem Experiments in a calorimeter?
Hello, I'm afraid I don't understand this homework question and would like a solution with an explanation. Thank you in advance. To verify Hess’s theorem, the following experiments were carried out in a calorimeter: a) Formulate the reaction equations b) Calculate the molar reaction enthalpy Note: The heat capacity of the solutions is approximately the…
Is this reaction equation correct?
It's the combustion of an alkane. Are these reaction equations correct? The second one is not complete, how do I do it?
Go ahead!
New areas are attacked and oxidized from the edges of the grate areas. There the grate particles are formed, which can be powdered away.
I have something against rust, so he has no chance, even at the edges.
Yeah? It’s understating the rust!
Yeah, that works.
With this I sprayed a fixed nut once and not 5 min. later she was able to turn up without resistance! :-))

If it’s rust converter, it’ll pull the oxygen out. After drying, remove with anti-rust paint etc. We’re back at once. Salmon, zetra.
that is often because the edges have been cut, hammered, deformed. A different crystal structure is thus present in these regions, which allows oxygen (red is a compound of iron with oxygen) to penetrate better.
My strength is also lower on canned, so there the grate is more effective.
Depending on how it has grown, iron rust can also develop a very good protective effect against environmental influences. Then the metal under the thick grate layer is better protected against the further rust than the “half rusted” material outside.
