A Chemical Reaction is a process that occurs when two or more molecules interact to form a new product(s). Compounds that interact to produce new compounds are called reactants whereas the newly formed compounds are called products.
The iron wool has a much larger surface area in contact with the air than a nail. This means that more iron is available to combine with the oxygen in the air. The other reason is the easier build-up of heat.
The "(II)" in the name tells you that the oxidation state is 2 (see below). You will know that it is +2 because you know that metals form positive ions, and the oxidation state will simply be the charge on the ion.
When you touch the 9 volt battery to it, the steel wool makes a completes the circuit of the battery. Steel wool is made mostly of iron which is extremely conductive. The surge of electrical current from the battery heats up the iron which causes it to react with the oxygen in the air surrounding it.
Iron burns with a dazzling flame, scattering sparks – incandescent particles of iron cinder Fe₃O₄. The same reaction of iron and oxygen also takes place in air, when during mechanical processing, steel heats up drastically from friction. 3Fe + 2O₂ = FeO • Fe₂O₃.
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Chemical reactions often involve color changes, temperature changes, gas production, or precipitant formation. Simple examples of everyday reactions include digestion, combustion, and cooking.
Chemical reactions are the processes by which chemicals interact to form new chemicals with different compositions. Simply stated, a chemical reaction is the process where reactants are transformed into products.
