Answer:
when iron come in contact of water or moisture is called rust
Explanation:
ok brooooooooo
Answer:
1. Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides and iron(III) oxide-hydroxide, and is typically associated with the corrosion of refined iro n
2. Hydrogen is a gas that burns with a 'pop' sound.
3. Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.
4.The reason is carbon's ability to form stable bonds with many elements, including itself. This property allows carbon to form a huge variety of very large and complex molecules. In fact, there are nearly 10 million carbon-based compounds in living things!
