Is rust formation an endothermic reaction because it absorbs energy?

Answer 1

Rust is exothermic.

The chemical reaction of iron and oxygen is called rust.

Try this easy experiment: place some finely spun iron (steel wool) over a very hot flame (such as a propane torch or bunsen burner). The steel wool will burn and turn grey after glowing red for some time.

This experiment will show that there is an exothermic reaction between iron and oxygen.

No, rust formation is not an endothermic reaction. It is an exothermic reaction because it releases energy. Rust formation occurs when iron reacts with oxygen in the presence of water to form iron oxide (rust). This reaction releases energy in the form of heat, making it exothermic.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
