To determine the mass of oxygen needed to oxidize 125 g of iron (Fe) to iron(III) oxide (Fe₂O₃), we first need to consider the balanced chemical reaction: 4 Fe + 3 O₂ → 2 Fe₂O₃. From the molar masses, iron has a mass of about 55.85 g/mol, so 125 g of iron is approximately 2.24 moles of Fe. According to the stoichiometry of the reaction, 3 moles of O₂ are required for every 4 moles of Fe, meaning about 1.68 moles of O₂ are needed. The mass of O₂ can be calculated as 1.68 moles × 32 g/mol = 53.76 g. Thus, approximately 53.76 g of oxygen is needed to oxidize 125 g of iron to iron(III) oxide.

What gas you needed to make iron rust?
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.
What is the compound needed to make iron 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.
Does 100g of iron turn into 100g of iron oxide?
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.
When Iron and oxygen are combine it forms iron oxide List the reactants and products of this reaction?
Reactants: iron an oxygen Product: iron(III) oxide, Fe2O3
Does iron reacts with water?
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 is?
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.
How many grams of oxygen are required to oxidize 140 g of Iron into IronIII Oxide what is the formula mass of the known?
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.
What gas you needed to make iron rust?
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.
Is rust combination of iron and oxygen?
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.
What is the compound needed to make iron 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.
Will oxygen and iron burn?
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.
What is the word equation for iron oxygen?
iron oxide
What 2 things are needed to make iron rust?
Whenever water or air is around iron for a while it can rust because the iron bonds to the oxygen forming iron oxide.
How rusting of iron needs both moisture and oxygen?
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.
How many grams of oxygen needed to get iron3 oxide?
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.
What elements are in 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.)
What is the main compound in rust?
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.
