Question

Steel wool is often used to clean up pans. Steel wool is mostly iron (Fe). In fact, steel is an iron alloy: iron with about 2% carbon. In lab, you burn steel wool, creating quite a spectacular glowing mass. What kind of property is being demonstrated, and how do you know?

Answer 1

We used a 9-volt battery to light the steel wool because the terminals are close together. Touching the battery to steel wool sends a current through the thin wire, and it heats up a lot (to about 700 degrees C). These temperatures cause the iron to react with the oxygen (O2) in the air and creates iron oxide (FeO2).

does that help?

Answer 2

A) Burning steel wool demonstrates a chemical property, flammability.
