Iron reacts with oxygen in air to for rust.
oxygen, to form rust
Iron can react with water in the presence of air and form rust.
Iron left damp and exposed to oxygen is prone to rust as the iron, water and air react to oxidize iron at the surface of the pan. Drying an iron skillet immediately after washing helps to protect the skillet from rusting.
yes
When iron reacts with air, they form ferric oxide.
If you expose iron to air then it gets rusty but it sure does take ime to get rusty.
No, hydrochloric acid does not need air to react with iron. When hydrochloric acid reacts with iron, you will notice the reaction because of the bubbling.
Bromine does not react with air because it is not possible. It is a non reactant element.
Oxygen
I think it's rust (iron oxide or hydrated iron oxide) because when iron reacts with water and air, rust is the product. At least that's what we were taught in science today!
Humidity ... damp air, water from rains.
Iron oxide is rust. It is formed when the element iron reacts with oxygen in the water or air.
most common metals tarnish slowly in exposure to air. metals that tarnish quickly in exposure to air are for example: lithium, sodium and potassium Gold is one of the slowest to tarnish.
