Iron is oxidized in the presence of oxygen and water to form rust. It is a chemical reaction in which electrons from the iron atoms are transferred to the oxygen atoms. The iron and oxygen atoms then form a compound. Most commonly, two iron (Fe) atoms will each give 3 electrons to be divided between 3 oxygen atoms, which take 2 electrons apiece. The balanced equation is:
4 Fe + 3 O2 --> 2 Fe2O3
What else can I help you with?
What can cause iron to rust and go through chemical weathering?
Iron rusts and undergoes chemical weathering due to exposure to oxygen and water. The process of rusting, known as oxidation, occurs when iron reacts with oxygen in the presence of water, forming iron oxide (rust). Over time, this chemical reaction weakens the iron and causes it to break down.
How do decomposers affect oxygen?
Decomposers are organisms that break down dead or decaying material. They affect oxygen levels by depleting them since they need oxygen to break down material.
What does the body break down during respiration?
Oxygen
What does a cell use to break down food?
oxygen
Why does painting an iron object slow down its rusting?
Painting an iron object creates a barrier between the iron and oxygen, which is necessary for rusting to occur. The paint acts as a protective layer that prevents the iron from coming into contact with moisture and air, thus slowing down the rusting process.
What would happen if we didn't have iron?
If we didn't have iron in our body, we will die. Iron is one of the big components of hemoglobin, the essential protein found in erythrocytes. Without iron, hemoglobin would not assemble properly and would not be able to pick up oxygen. Without the blood picking up oxygen, the body will starve and will have an excess build up of CO2. As cells begin to break down due to lack of oxygen, you will die.
What is a type of chemical weathering apex?
One type of chemical weathering is oxidation, where minerals containing iron are exposed to oxygen and water, causing the iron to rust and the rock to weaken and break down.
What does Fe2S3 break down into?
Iron(III) sulfide (Fe2S3) breaks down into iron(III) oxide (Fe2O3) and sulfur dioxide (SO2).
Oxygen weathers rock through a process called?
oxidation. Oxygen reacts with minerals in rocks to form oxides, which causes the rocks to break down and weather over time. Rusting of iron minerals is a common example of this process.
What process uses oxygen and break down glucose?
respiration
Do humans break down sugars into energy or oxygen?
they break sugar down using enzymes which are proteins, into energy, oxygen is used as an energy supplier to the reaction which creates water and Co2
The break down of food without oxygen?
anaerobic respiration is the breakdown of food without oxygen.
