Chemical reaction between iron and oxygen, which is given by the formula 4Fe + 3O2 = 2Fe2O3. This formula shows that when iron is found in the presence of oxygen, the two chemicals join together to form a new compound. This reaction is called an oxidation/reduction reaction and represents the other (along with acid/base reactions) most common type of chemical reaction. In an acid / base reaction, a proton (H+) gets transferred from one substance to another. In an oxidation/reduction reaction electrons get transferred from one substance to another. In this reaction iron transfers some of its electrons to oxygen. The iron atom becomes an Fe+3 ion and oxygen becomes an 0-2 ion, which quickly joins with an H+ ion to form water. These two elements combine to form iron oxide, or rust. During the corrosion process, iron does not seem to react with air at all. Water is necessary for the oxidation reaction to occur, to facilitate transport of the electrons, although we do know that iron will rust in air after a long time, since there are water droplets in the air. Another substance that facilitates the transport of electrons is vinegar. 2 Fe + O2 + 2 H2O ---> 2 Fe 2+ + 4 OH-
2 Fe + O2 + 2 H2O ---> 2 Fe(OH)2
sorry the little 2's and + - ions are not shown correctly here. Yahoo does not allow subscript and super script.
The Fe (OH)2 is further oxidized to Fe(OH)3 :
4 (Fe+ii - 1 e- ---> Fe +iii)
adding +8 OH- to both sides of the formula yields,
4 Fe(OH)2 + O2 + 2 H2O ---> 4 Fe(OH)3
and 2 Fe(OH)3 ---> Fe2O3 + 3 H2O
The oxide breaks into pieces so that the oxidation continues even further.

∙ 11y agoIt is a synthesis reaction, because you are taking 2 elements and combining them chemically to produce a compound. Iron rusts when it reacts with oxygen in the air. The balanced equation is 4Fe + 3O2 --> 2Fe2O3.

∙ 14y agoThe rusting of iron is a combination reaction, because iron and oxygen are combined to create iron oxide, which is more commonly known as rust.

What type of reaction occurs and how does the mass of the object after rusting compare with its original mass?
1. Rusting is an oxidation reaction of iron.2. The mass of an object increase after rusting.
What type of chemical reaction occurs when copper rust?
Rusting is a reduction/oxidation reaction.
What type of change is it when you heat a mixture of powdered iron and sulfur iron?
It is a chemical reaction
Is magnetization of iron a chemical reaction?
No, magnetization is not a chemical reaction. Magnetic iron and non-magnetic iron are chemically the same substance. Magnetization is a process of alignment of atomic magnetic fields, which is a purely physical change, not a chemical change.
How do you make iron rust faster?
The rustin of iron can be treated as any other chemical reaction. Increasing temperature increases the rate of reaction. Hence increasing temperature can increase the rate at which iron rusts.
What is the chemical reaction for rusting?
2Fe + 02 --> 2FeO (depending on the type of iron)
Why is rusting a chemical change?
Rusting is a reaction which combines molecules to form other molecules: metal + oxygen -> rust. The definition of a chemical reaction is molecules turning into other molecules, so rusting is a chemical reaction.

Chemical change
Why does metal rust and what is the chemical reaction for rusting?
== == Being a layman, this answer will be a lay answer, until a chemist can improve it. The word rust is often used generically to describe the corrosion of several metals, BUT in actuality, ONLY IRON, or metal alloys containing IRON can rust. Most metal do corrode, but the term rust applys only to ferrous [iron] metals. The rusting of iron is an oxidation-reduction type of chemical reaction whereby oxygen combines with the outer region of the iron containing metal.
What type of change is it when you heat a mixture of powdered iron and sulfur iron?
It is a chemical reaction
What type of reaction occurres when iron has rusted and how does the mass of the object after rusting compare with its original mass?
The mass would be greater
Rusting of iron is a slow type of combustion?
Rusting is an oxydation but not a combustion.
