Burning Steel Wool is a Chemical Reaction The chemical equation for this reaction is 2H 2 (g) + O 2 → 2H 2 O (g) I use this reaction as one of five science investigations in my unit for Middle School Science on Chemical Reactions.
Is steel wool a compound or mixture?
Steel wool is made from an iron alloy, not a chemical compound with a formula. Is steel wool a physical or chemical change? Is steel wool a physical or chemical change?
What is the chemical equation for the chemical reaction of steel wool?
This is proof that that the steel wool has been chemically changed into the compound iron oxide. The chemical equation for this reaction is 2H 2 (g) + O 2 → 2H 2 O (g) I use this reaction as one of five science investigations in my unit for Middle School Science on Chemical Reactions.
What is the carbon content of steel wool?
The steel from which steel wool is made is called low-carbon steel and contains between 0.1 and 0.3 percent carbon by mass. An alloy like steel wool is a mixture of metals that results when two or more metals are melted and combined.
What happens when you burn steel wool?
When the steel wool burns, it is oxidized and thus this is a chemical change. What is the chemical formula of steel? Steel wool is made of small ribbons of steel, and steel is an alloy of iron with a percent or so of carbon. There will be some traces of other metals in it as well.
What compound is steel wool?
The first thing to understand is that steel wool is actually mostly iron (Fe). In fact, steel is an iron alloy: iron with about 2% carbon mixed in. For simplicity, lets just say it's mostly iron. We used a 9-volt battery to light the steel wool because the terminals are close together.
Is steel wool a chemical reaction?
Steel Wool has a protective coating that keeps oxygen from coming into contact with the iron. Vinegar contains acetic acid which removes this coating. When the protective coating is removed, oxygen in the atmosphere can reach the iron in the steel wool and a chemical reaction called oxidation occurs.
What is the chemical equation for steel?
Steel is a mixture of iron and carbon fused together with one or more other metals or nonmetals. Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula.
Does steel wool have chemicals?
(While steel wool is often covered in other chemicals — powdered soap, for example — only the iron is burning and mixing with oxygen.) Air is only 20 percent or so oxygen, so the burning happens at a kind of half-speed that looks like a cartoon dynamite fuse.
What happens if you mix steel wool and vinegar?
When you soak the steel wool in vinegar it removes the protective coating of the steel wool and allows the iron in the steel to rust. Rusting (or oxidation) is a chemical reaction between iron and oxygen, this chemical reaction creates heat energy which increases the temperature inside the beaker.
What is the formula for rust?
Rust is apparently a hydrated form of iron(III)oxide. The formula is approximately Fe2O3•32H2O, although the exact amount of water is variable. (Note that this is about halfway between iron(III) hydroxide, Fe(OH)3 or ½{Fe2O3•3H2O], and anhydrous Fe2O3).
What is steel made of chemically?
steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron).
What is steel composition?
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements.
What is the symbol of steel?
Steel is not an element. It is largely iron, but has many other elements in it, alloying elements as well as impurities and residuals. The commonly found elements are, Fe, Cr, Ni, Mn, C, Si, S, P, N, Al, As, Be, B, Co, Cu, H, Mg, O, Nb, Se, Ti, W, V, Zr.
Is steel wool poisonous?
INHALATION: Overexposure can cause irritation to the respiratory tract. Symptoms may include coughing and shortness of breath. CONTACT WITH SKIN or EYES: If exposure to dust or particles of steel wool occurs to the eye, it may cause irritation, redness and pain.
What happens when you mix steel wool and oxygen?
Steel wool (iron) will burn in air quite gently, since air is about 20% (by volume) oxygen. When the steel wool is placed in 100% oxygen the reaction proceeds much faster and vigorously.

What type of reaction is steel wool and battery?
When the strands of steel wool touch both terminals of the battery, they will complete the circuit and cause electricity to flow. This will heat up the steel wool, which will cause it to react with the oxygen in the air, or in other words, BURN!
What is the reaction of steel wool and oxygen?
Steel wool (iron) will burn in air quite gently, since air is about 20% (by volume) oxygen. When the steel wool is placed in 100% oxygen the reaction proceeds much faster and vigorously.
What is observed in steel wool reaction?
Learners may see the steel wool burning and bright orange sparks falling. They may even notice some smoke. Learners may hear the crackling sound of the steel wool burning. Learners may notice a metallic smell in the air.
Why does the steel wool ignite?
These iron threads have a lot of surface area surrounded by pockets of oxygen. When both battery terminals touch the steel wool, the electrons from the battery move rapidly through the steel wool creating a complete circuit. The electrical current heats up the wire (700 degrees). The heat causes the iron to react with the oxygen surrounding the steel wool. This reaction creates the spark that we see and the release of heat that heats up the next iron molecules, thus causing chain reactions through the steel wool. The very bright light is because of the extreme heat. This chemical reaction of iron and oxygen, also, creates a new substance, iron oxide (FeO2). Iron oxide is heavier than iron, making the resulting product heavier than the original steel wool. This experiment is an example of an exothermic reaction, a chemical reaction that releases energy in the form of heat. Once the steel wool has burned , it is a greyish color and can no longer be ignited. This is proof that that the steel wool has been chemically changed into the compound iron oxide.
What happens when the battery terminals touch the steel wool?
When both battery terminals touch the steel wool, the electrons from the battery move rapidly through the steel wool creating a complete circuit. The electrical current heats up the wire (700 degrees). The heat causes the iron to react with the oxygen surrounding the steel wool.
Does wood burn with oxygen?
Wood actually lets out combustible gases as it burns, which react immediately with oxygen. Iron doesn’t do this. Since our atmosphere is only 20% oxygen anyway, it takes some special measures to get enough oxygen to react with iron to cause combustion. Chemical Reactions.
Is iron flammable?
Normally we do not think of iron as being flammable, this is because bulk iron doesn ’t self-sustain its bur ning like most flammable materials. But the strands of steel wool are thin enough with enough surface area that heat produced is self-sustaining and will continue to burn through if there is enough air present.
What is steel wool burned in?
Steel Wool is burned in an oxygen rich environment which dramatically increases the rate of reaction.
How to burn steel wool?
Procedure. Fill the cylinder with oxygen and cover it with a large glass square. Holding a piece of steel wool with tongs, ignite the steel wool by placing it in the flame of a bunsen burner. Quickly remove the glass cover and put the glowing steel wool into the oxygen. The steel wool will burn very brightly.
Does steel wool burn brightly?
The steel wool will burn very brightly.
