Steel Wool + Oxygen Chemical Reaction

By- Lilly McMichael + Catherine Halstead

Graph of Experiment

When steel wool and oxygen make contact the temperature increases at a steady pace.  This is an exothermic reaction because energy was being released.  In our experiment the lowest temperature was 23 degrees Celsius and the highest temperature was 33 degrees Celsius .

Chemical Equation

Fe + O2 --> Fe2O3

During the reaction of steel wool and oxygen, steel wool mixes with the oxygen which creates iron oxide.  The reactants in this experiment are iron (Fe) and oxygen (O).  When these 2 elements bond together their product is iron oxide.

Law of Conservation of Mass

In our experiment the Law of Conservation of Mass is demonstrated below.

Reactants:                                                                                                 Products:

4 Fe                                                                                                             4 Fe

6 O                                                                                                               6 O                                                                                                    Balanced Equation

                                                           4Fe + 6O --> 2FeO3

Chemical Reaction Evidence

In the experiment we knew that there was a chemical reaction occurring.  We knew this because there were a few key pieces of evidence.  After about 30 seconds of the steel wool making contact with oxygen a very gross smell started to come from the steel wool.  Also, the steel wool turned from a dark grey color to a greenish-black color.
