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.
Which has the greatest density water granite iron or dry air?
Iron has the greatest density, followed by granite, water, and then dry air. Density is the mass per unit volume of a substance, and iron has a higher mass per unit volume compared to granite, water, and dry air.
Water plus air plus iron equals?
The combination of water, air, and iron can lead to the formation of iron oxide (rust) on the surface of the iron due to the process of corrosion. This chemical reaction occurs when iron reacts with the oxygen in the air and water, leading to the characteristic reddish-brown color of rust.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
What brings about rusting of iron change?
Rusting of iron occurs when iron is exposed to oxygen and water, which leads to the formation of iron oxide (rust) on the surface of the iron. The presence of both oxygen and water is necessary for the rusting process to occur. Rusting can be accelerated by factors such as saltwater, acids, and pollutants in the atmosphere.
What happens when air is combined with substances like iron and water?
Air, iron and water will cause the iron to rust.
What type of change is rust formed into iron after exposure to air?
The formation of rust when iron is exposed to air is a chemical change. This process, known as oxidation, occurs when iron reacts with oxygen in the presence of water to form iron oxide, which is what we see as rust.
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.
When iron oxide is made does the iron take the oxygen out of the water or out of the air?
Iron oxide is typically formed by the reaction of iron with oxygen in the air, not water. Iron reacts with oxygen in the presence of air to form iron oxide. Water does not play a significant role in the formation of iron oxide in this context.
Which has the greatest density water granite iron or dry air?
Iron has the greatest density, followed by granite, water, and then dry air. Density is the mass per unit volume of a substance, and iron has a higher mass per unit volume compared to granite, water, and dry air.
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.
Is an iron nail rusts a phisical change?
It is a chemical change. Oxygen in the air (and sometimes water vapor) combines with the iron to form oxides. The rust is a new chemical with very different properties: it has little strength, can be washed away, and is no longer attracted to a magnet.
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.
Water plus air plus iron equals?
The combination of water, air, and iron can lead to the formation of iron oxide (rust) on the surface of the iron due to the process of corrosion. This chemical reaction occurs when iron reacts with the oxygen in the air and water, leading to the characteristic reddish-brown color of rust.
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.
