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.

What type of reaction occurs and how does the mass of the object after rusting compare with its original mass?

Rusting is a chemical reaction known as oxidation. When a metal object rusts, it gains mass because the iron in the metal reacts with oxygen to form iron oxide (rust). The mass of the object after rusting will be greater than its original mass due to the addition of the iron oxide.


How are rusting the same as burning?

In some ways. Rusting is an oxidation reaction similar to fire and it does release heat, but it is so slow that the heat does not affect the reaction. In a fire the heat released goes helps sustain the reaction.


What type of change is it when you heat a mixture of powdered iron and sulfur iron?

The change is a chemical change known as a chemical reaction. When heated, the iron and sulfur react to form a new compound called iron sulfide.


How is rusting and transmutation related?

Rusting is a specific type of oxidation reaction that occurs when iron reacts with oxygen in the presence of water to form iron oxide. Transmutation, on the other hand, is the process of changing one element into another through nuclear reactions. While both rusting and transmutation involve chemical or atomic changes, they occur through different mechanisms and at different scales.


What type of reaction produces iron?

Iron is typically produced through a chemical reduction reaction of iron ore (Fe2O3) with carbon in a blast furnace, resulting in the production of metallic iron. This reaction is a form of chemical reduction, where iron oxide is reduced to elemental iron by the carbon monoxide produced in the furnace.

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.

What type of energy causes rusting to occur?

Rusting occurs due to a chemical reaction between iron, oxygen in the air, and water, resulting in the formation of iron oxide. This reaction is driven by both chemical energy and environmental factors such as humidity and temperature.

Rusting of iron is a slow type of combustion?

Rusting is a chemical process where iron reacts with oxygen in the presence of water to form iron oxide. This is a slow process compared to traditional combustion, such as burning wood, where a rapid chemical reaction releases heat and light energy. Rusting does not produce flames or a dramatic release of energy like combustion.


What type of reaction occurs and how does the mass of the object after rusting compared with its original mass?

1. Rusting is an oxidation reaction of iron.2. The mass of an object increase after rusting.


The type of weathering that is commonly known as rusting?

The type of weathering commonly known as rusting is chemical weathering. It occurs when metals, such as iron, are exposed to oxygen and water, causing a chemical reaction that forms rust. Rust weakens the metal structure over time, leading to its deterioration.

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.
