because the iron bonds with oxygen, so the weight becomes the original weight of iron plus the original weight of Oxygen.

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.

∙ 13y agoIron gets heavier as it rusts, because it bonds with the oxygen in the air, adding mass to the iron.
Wiki User
∙ 16y agoBecause oxygen molecules have bonded with the iron and added their weight to the mass.

∙ 12y agoWhen the iron rusted, it reacted with oxygen to form iron oxide, which is rust. So, the new mass is the original iron plus the mass of the oxygen that combined with it.

What transition metal rusts when exposed to oxygen?
Iron is the transition metal that rusts when exposed to oxygen, forming iron oxide.
Which metal rusts first copper or iron?
Iron rusts first because it is more reactive than copper. When iron comes into contact with oxygen and water, a chemical reaction occurs that forms rust, whereas copper does not rust easily due to its lower reactivity.
Witch metal does rust the fastest iron bronze?
Iron rusts fastest compared to bronze. Iron is more susceptible to corrosion due to its chemical composition, which reacts with oxygen in the air to form iron oxide (rust). Bronze, on the other hand, is a copper alloy that is more resistant to corrosion compared to iron.
What is the reducing agent when iron rusts?
The reducing agent when iron rusts is the iron itself. Iron atoms lose electrons to oxygen atoms in the presence of water and oxygen gas, leading to the formation of iron oxide (rust).
When iron rusts iron atoms are destroyed true or false?
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
What transition metal rusts when exposed to oxygen?
Iron is the transition metal that rusts when exposed to oxygen, forming iron oxide.
What do you see when iron rusts?
When iron rusts, it forms a reddish-brown coating on the surface. This coating is a combination of iron oxide, and it can flake off, exposing more of the iron underneath to continue the rusting process.
What happens to iron when it is in air and gets wet?
It rusts. Check the "related links" if you are concerned for more information regarding the chemical reactions that take place and the different products formed when iron rusts.
Which metal rusts first copper or iron?
Iron rusts first because it is more reactive than copper. When iron comes into contact with oxygen and water, a chemical reaction occurs that forms rust, whereas copper does not rust easily due to its lower reactivity.
Witch metal does rust the fastest iron bronze?
Iron rusts fastest compared to bronze. Iron is more susceptible to corrosion due to its chemical composition, which reacts with oxygen in the air to form iron oxide (rust). Bronze, on the other hand, is a copper alloy that is more resistant to corrosion compared to iron.
What rusts faster?
iron
Is iron nail biodegradable?
No. Iron rusts but it is not biodegradable.
Why is most Iron in the world not found as the metal?
Iron rusts.
Why does the iron rusts when magnesium is put in the water with the iron?
When magnesium is put in water with iron, the magnesium acts as a sacrificial anode due to its higher reactivity. This causes the magnesium to corrode instead of the iron, protecting the iron from rusting. This process is known as cathodic protection.
What is the reducing agent when iron rusts?
The reducing agent when iron rusts is the iron itself. Iron atoms lose electrons to oxygen atoms in the presence of water and oxygen gas, leading to the formation of iron oxide (rust).
Is rust a carbon?
No. When iron rusts, it becomes iron oxide, or more specifically, iron (II) oxide or iron (III) oxide. Fe + O --> FeO iron oxygen iron (II) oxide
When iron rusts iron atoms are destroyed true or false?
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
