Reaction when iron wool burns

WebWhen burned over a Bunsen burner, the iron wool is being burned in air. Air contains 2 1 % of oxygen, a medium to low concentration. The rate of reaction is quite low, and the iron wool burns relatively slowly. However, when burned in pure oxygen the reaction is much more rapid and intense. WebIron filings sparkle when you shake them into a flame; iron wool also sparkles, but not as excitingly. But laboratory tongs are also made of iron. You can heat these to red heat for ages, and they won't burn in air. So is iron very reactive or not? Think about aluminium as well. The powder blown into a flame burned immediately and fiercely.
