Transcribed Image Text: One of the most recognizable corrosion reactions is the rusting of iron. Rust is caused by iron reacting with oxygen gas in the presence of water to create an oxide layer. Iron can form several different oxides, each having its own unique color. Red rust is caused by the formation of iron(III) oxide trihydrate.
When an iron object rusts, its mass increases. When a match …
The given statement tells that when an iron object rusts, its mass increases. When an iron object rusts, the change in state of iron occurs as iron reacts with oxygen and result in the formation of iron oxide. The addition of oxygen to iron increases …
