Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
No, when 100g of iron reacts with oxygen to form iron oxide, the resulting compound will have a different mass than the initial iron due to the addition of oxygen atoms. The mass of the iron oxide formed will be greater than 100g, as the oxygen atoms combine with the iron atoms to form the compound.
Reactants: iron an oxygen Product: iron(III) oxide, Fe2O3
Pure Iron (Fe) doesn't directly react with water, but it will oxidize (rust), especially if the iron is just wet and is exposed to air a lot. I believe iron will eventually oxidize if kept completely underwater too, but as there is less free Oxygen for it to react with down there, it is a longer process.
The oxygen that rusts iron comes from the air. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, known as rust.
To calculate the amount of oxygen needed to oxidize iron, we need to use the stoichiometry of the reaction. The equation for the reaction of iron with oxygen to form iron(III) oxide is: 4 Fe + 3 O2 -> 2 Fe2O3. This shows that 3 mol of O2 are required to react with 4 mol of Fe. So, we first need to calculate the number of moles of Fe in 140 g of Iron, then use the stoichiometry to determine the number of moles of O2 needed. The molar mass of Iron(III) oxide (Fe2O3) is 159.69 g/mol.

Yes, rust is a chemical compound that forms when iron reacts with oxygen in the presence of water or moisture. This reaction causes iron to oxidize, forming iron oxide, commonly known as rust.
Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
Oxygen can support combustion, but iron itself does not burn in typical atmospheric conditions. However, iron can oxidize, forming iron oxide (rust), in the presence of oxygen and moisture. This process is a slow form of oxidation rather than rapid combustion.
iron oxide
Whenever water or air is around iron for a while it can rust because the iron bonds to the oxygen forming iron oxide.
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
Rusting of iron is a chemical reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust). The presence of moisture is necessary to allow the iron to dissolve and come into contact with oxygen from the air, initiating the rusting process. Without oxygen, the iron cannot oxidize to form rust.
To form iron(III) oxide, the chemical equation is: 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) From the equation, it can be seen that 3 moles of oxygen (O2) are needed to react with 4 moles of iron (Fe) to produce 2 moles of iron(III) oxide (Fe2O3). The molar mass of oxygen (O2) is approximately 32 g/mol. Therefore, you would need 96 grams of oxygen to react with the iron needed to form iron(III) oxide.
The scientific name for rust is iron oxide. It is made up of the elements iron and oxygen. Turning iron to iron oxide is an example of corrosion.
