Observations After Interaction Steel Wool + Oxygen
➪<em> </em><em>Steel wool in simple words is Iron. When it comes in contact with air and water it starts the process of rusting which is a type of slow combustion. A layer of brown substance coats the iron which is the result of the reaction...~ </em>
By placing the steel wool in a jar with plenty of oxygen and water, you start a chemical reaction. The iron and the oxygen react to form a new reddish-brown substance, called iron oxide or rust. In this experiment, the water level in the glass should rise as the oxygen inside combines with the iron in the steel wool.
