Graphing It

When oxygen and steel wool were combined, the temperature is increased.This is an exothermic reaction because energy/heat was absorbed. The lowest temperature was 27 degrees Celsius and the highest temperature was 34.4 degrees Celsius.

Breakdown of the Reaction

Steel wool, also known as wire wool or wire sponge, is a bundle of very fine and flexible filaments. Steel wool isn't even made of steel or wool. Steel wool is made of iron. Oxygen is a colorless, odorless gas found in the air. This reaction not only changes temperature, it also changes the steel wool to a goldish color.

Evidence of the Chemical Reaction

4Fe + 3O2 = 2Fe2O3

In this reaction, solid iron is mixed with with gas oxygen and makes iron oxide. The reactants are oxygen and iron and the product is iron oxide. The Law of Conservation of Matter is shown as follows:

reactants:                                                                                   products:

4 Fe                                                                                                 4 Fe          

6 O                                                                                                   6 O
