The mass increases until the rust flakes off,which leaves less original mass. Eventually the gate will rust completely away.

When iron rusts the resulting substance has a greater mass than the original iron With which theory does this seem to agree?
lol figure it out i ain't a geek don't ask me
When an iron nail rusts does its mass lose?
The iron nail, in wet conditions, will eventually rust completely away. * * * * * But if you collect all the rusted particles that fall away, then there will be an increase in mass.
Why does steel wool turn blue after it's burned?
Iron wool gains mass when it is burnt because the oxygen in the fire oxidizes and rusts the iron. The additional oxygen molecules on the iron wool in the form of rust increases the mass of the wool.
How do we know that a chemical reaction takes place when iron rusts?
- the mass of the initial iron is increased - the color and appearance of iron oxides is different compared to the color of iron - the physical properties are modified - the chemical properties are modified
How do you find moles in iron?
The molar mass of iron is 55,845 g.Moles of iron = mass of iron/55,845
Why does iron weigh more after it rusts?
because the iron bonds with oxygen, so the weight becomes the original weight of iron plus the original weight of Oxygen.
Why would the mass of a rusted nail would be greater than the mass of the nail before?
When iron rusts, it combines with oxygen to form iron oxide (rust). You now have the original mass of iron PLUS the mass of the combined oxygen.
When an iron nail rusts what does its mass do?
The iron is reacting with other substances in the surrounding enviornment. This typically changes the iron atoms into molecules of iron oxide. Because the rust contains more atoms, the iron and now oxygen atoms, the mass of the nail increases.

If there are 3 grams of iron in a sealed container with most air the sealed container with iron moist air weighs a total 5 grams will there be 3 grams of rust if all the iron rusts?
No, iron oxide weighs more than pure iron. The iron will pick up the extra mass of the oxygen molecules that bond with it.
Does increasing of mass of rusty iron violate the low of conservation of mass?
No, because the principle of conservation of matter states that during a chemical reaction, matter is neither created nor destroyed. The total mass of reactants MUST equal the total mass of products.
Why does steel wool turn blue after it's burned?
Iron wool gains mass when it is burnt because the oxygen in the fire oxidizes and rusts the iron. The additional oxygen molecules on the iron wool in the form of rust increases the mass of the wool.
What is indication of a chemical reaction?
HEAT, Heat is the the number one indication of a reaction. Also, changes of state of matter and mass are also indicators of a chemical reaction. an example is when an iron fence rusts.
When iron rusts does its weight increase or decrease?
Actually it doesn't affect its weight at all. During the chemical change that occurs when iron rusts, the weight does not change because weight never changes during a chemical reaction because nothing new is being created nor destroyed, only combined.
How do we know that a chemical reaction takes place when iron rusts?
- the mass of the initial iron is increased - the color and appearance of iron oxides is different compared to the color of iron - the physical properties are modified - the chemical properties are modified
Why is the mass of a rusted nail greater then the mass of the nail before it rusted?
The nail is iron. Rust is a chemical reaction. 4Fe + 3O2 --> 2Fe2O3 When the nail rusts it becomes chemically bonded to oxygen. This combination is heavier than just iron. Therefore, it gains mass.
