Question

(4 marks)
a. Describe what you would observe if an object made of iron was left out in the open for
a long time. Why would you observe this?

​

Answer 1

Answer:

If an object made up of iron was left out in the open for a long time it would get rusted. ... The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.
