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 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.
How fast a nail will rust by water?
This really depends on the concentration of impurities in water. More the impurities, faster it will rust the iron nail. To reduce rusting of any iron the best way is to paint the nail.
Is a rust forming on an iron nail chemical or physical?
A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.
Explain why the mass of a rusted nail would be greater than the mass of the nail before it rusted Assume that all the rust is still attatched to the nail?
When a nail rusts, iron in the nail reacts with oxygen in the air to form iron oxide (rust), which has a greater mass than iron alone. As a result, the overall mass of the nail increases when it rusts because the mass of the iron in the nail combines with the mass of the oxygen in the air to form iron oxide.
What happens to nail after heating?
It either cleans the nail, or makes the nail have rust.
Can rusting happens with iron nail when it is kept in distilled water?
Yes, rust happens to iron nail though it is kept in distilled water.
What happens to a nail when it sokes in coke with?
the nail will get shiny the coke will get rid of all rust on iron. We use coke to clean the rust of our bicycles
Why does saltwater make a nail rust?
It's not just saltwater that makes a nail rust, even water makes a nail rust. Rust is simply oxidation, it happens when oxygen comes into contact with something and creates a chemical reaction and creates "oxides". Iron + oxygen = Iron oxide (red rust on steel)
When a nail rust iron from the nail combines with oxygen from the air to form what?
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
Why does an iron nail rust?
Iron present in the nail oxidizes in oxygen to form the iron oxides
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.
Is rust forming on an iron nail is that a mixture?
Rust forming on an iron nail is a chemical reaction rather than a mixture. Rust is a compound made up of iron oxide that results from the reaction of iron with oxygen and water in the presence of air.
Why a rusty nail weighs 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.
Can you reverse an iron nail rusting?
NO!!!! There is a phycial chemical equation named the 'Gibbs Free Energy Change'. If the calculations result in a negative answer then the reaction is feasible, but the reverse (positive answer) is NOT feasible. DeltaG = DeltaH - T*DeltaS is the basic equation. DeltaH is the enthalpy change (kJmol^(-1) DeltaS is the entropy change (J mol^(-1)(K^(-1)) Careful with these units and their conversion. T is the temperature in (Kelvin(K)). So without putting in any numbers, for the rusting of iron 'DeltaG is negative(-). However, to try and make the reaction go the otherway , then DeltaG is positive(+), and so is NOT feasible.
What happens if you put an iron nail into vinegar?
When an iron nail is placed in vinegar, a chemical reaction occurs that causes the iron to rust. This process is known as corrosion, where the vinegar reacts with the iron to form iron oxide. Over time, the iron nail will continue to corrode and develop a reddish-brown layer on its surface.
Can a nail rust?
it can rust it reacts with atmosphere and reacts with iron oxide then it get rusted
