When iron (Fe) rusts, it combines with oxygen (O2) to form various forms of iron oxide such as Fe2O3, Fe3O4, or FeO2. In each of these there are oxygen molecules bonded to the iron. The oxygen comes from the air, water or other solution. So an object which was formally pure iron, once rusted, will contain additional mass from the oxygen and weigh more than it did before.
What else can I help you with?
Why does the rusty nail weigh more than the original nail?
The rust that forms on the nail is actually iron oxide, which has a greater molecular weight than iron. This additional weight from the rust causes the rusty nail to weigh more than the original nail.
Why does powdered iron rust?
Powdered iron rusts more easily because the increased surface area allows for greater exposure to oxygen and moisture, which are the primary causes of rusting. The smaller particles of powdered iron have a larger surface area compared to solid iron, leading to a faster reaction with oxygen and water.
Why does a rusty nail weigh more than the original nail?
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Does a pound of feathers weigh more than a pound of iron what truly is the difference between the two?
No, a pound of feathers and a pound of iron weigh the same, as they both weigh one pound. The difference between the two is their density and composition - feathers are less dense and made of organic material, while iron is a denser metal.
Why does rust weight more?
Rust is typically denser than the original iron or steel it forms from, which means it weighs more for the same volume of material. This is because rust has a larger molecular structure compared to iron, leading to an increase in mass.
Why does the rusty nail weigh more than the original nail?
The rust that forms on the nail is actually iron oxide, which has a greater molecular weight than iron. This additional weight from the rust causes the rusty nail to weigh more than the original nail.
When powdered iron is left exposed to air it rest Y is the mass of the rest is greater than the mass of the powdered iron?
I believe the mass is greater as rust is the combination of iron plus oxygen, similarly the smoke and ash from a fire, if collected, would weigh more than the fuel alone before it was burnt. strange but true. Ask a chemistry boffin to prove the maths.
This reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron?
A reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron has a much greater surface area and all chemical reactions take place on surfaces.
Why does powdered iron rust?
Powdered iron rusts more easily because the increased surface area allows for greater exposure to oxygen and moisture, which are the primary causes of rusting. The smaller particles of powdered iron have a larger surface area compared to solid iron, leading to a faster reaction with oxygen and water.
Does iron weigh the same as iron oxide?
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
How does a rusty nail weigh more than an original one?
A rusty nail may weigh more than a new one due to the oxidation process. Rust is formed when iron reacts with oxygen, adding mass to the nail. The rust layer can make the nail heavier than when it was in its original form.
Which weights more.1kilo of iron or 1 kilo of cotton?
They weigh the same, as they both weigh 1 kilogram.
What is fingerprint powder made of?
Depending upon conditions which might call for more exotic media, the most commonly used substances are powdered graphite and/or powdered iron filings.
Why does a small volume of iron weigh more than a large ball of cotton?
Because iron is much more dense.
Why does a rusty nail weigh more than the original nail?
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Why does iron weigh more after it rusts?
Iron weighs more after it rusts because rust is formed by the addition of oxygen from the surrounding environment. This increase in weight is due to the formation of iron oxide layers on the surface of the iron, which adds to the overall mass of the object.
Which would weigh more a brick made of iron or the samesize brick made oflead?
A brick made of lead would weigh more than a brick made of iron of the same size. This is because lead is denser than iron, meaning it has more mass packed into a similar volume.
