Which has the greatest density water granite iron or dry air?
its, IRON
Is rusting of an iron fence physical change?
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
Water plus air plus iron equals?
Rust
What would happen to iron railings if they are not painted?
They would rust. Iron reacts with the air or water to create iron oxide which is the scientific name for rust. The paint acts as a protective coating stops the air getting to the iron.
What happens when air is combined with substances like iron and water?
Air, iron and water will cause the iron to rust.

When iron oxide is made does the iron take the oxygen out of the water or out of the air?
It takes the oxygen from air because without the presence of air, iron cannot turn into ferric oxide. The iron first reacts with air and then reacts with water to form rust.
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
Which type of change is a rusting bicycle physical or chemical?
The steel of your bike contains iron, which becomes iron oxide [which is rust]. It has reacted with oxygen in the air. Water in the air makes this happen more easily which is why you should keep your bike dry, or at least keep your bike painted well so that the iron/steel doesn't come in contact with air. The iron and oxygen were separate at the beginning, and are bonded together into a new substance at the end, so that tells us that this is a chemical change. A physical change is one where no new substance is made, but the substances we already had get reorganised. For example. when water boils, the steam is still the same molecule, water, just reorganised.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
What kind of change iron to rust?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
Was does iron react with?
Iron can react with water in the presence of air and form rust.
Which way in gold behave like iron or differently from iron?
Gold is not affected by air or water but iron is affected by air or water as it rusts
What makes well water change color?
The minerals in the soil where the water comes from. Frequently it is copper. Iron will also cause the water to change color as will oxygen, which will cause minerals in the water to change (iron oxidizes).
What else is needed for iron to go rusty?
Water and oxygen are both needed. Without either one the iron will not rust.
