Is a rusty nail physical or a chemical change?
The rusting of a nail is a chemical change. This is because the iron in the nail reacts with oxygen in the air to form iron oxide, which is the rust. This process involves a chemical reaction and results in a change in the composition of the nail.
Is iron rust physical change or chemical change?
The rusting of iron is a chemical change because the iron reacts with oxygen in the air to form iron oxide. This process cannot be reversed by physical means and results in a new substance being formed.
Is filtering air to remove dust and pollen a physical or chemical change?
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.
Is formation of silver sulfide when silver reacts with sulfur in the air a physical change?
chemical, specifically an "oxidation" reaction (even though oxygen is not involved).
Is Mg burned in air chemical or physical?
Burning Mg in air is a chemical change. When magnesium reacts with oxygen in the air, it forms magnesium oxide. This is a chemical reaction that results in the formation of a new substance with different properties than the original magnesium.
Is a Silverware tarnishing a physical or Chemical change?
It's a chemical change. The silver reacts with sulfur compounds from the air.
What about tarnishing of silver is chemical or physical change?
It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.

Is burning a magnesium ribbon a physical change?
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.
Is Mg burned in air chemical or physical?
Burning Mg in air is a chemical change. When magnesium reacts with oxygen in the air, it forms magnesium oxide. This is a chemical reaction that results in the formation of a new substance with different properties than the original magnesium.
Is silver tarnishing a physical or chemical change?
Silver tarnishing is a chemical change. It occurs when silver reacts with sulfur compounds in the air to form a layer of silver sulfide on the surface. This chemical reaction changes the composition of the silver, resulting in the tarnished appearance.
Is tarnishing silverware a physical change or chemical change?
Tarnishing silverware is a chemical change. It occurs when silver atoms react with sulfur compounds in the air or on the surface of the silverware, forming silver sulfide. This chemical reaction changes the composition of the silverware, making it appear tarnished.
Is a gate rusting a physical or chemical change?
The rusting of a gate is a chemical change. It occurs when the iron in the gate reacts with oxygen in the air and moisture to form iron oxide (rust), which is a new substance with different properties than the original iron.
Is it physical or chemical change a silver spoon tarnished?
Tarnishing of a silver spoon is a chemical change. It occurs when the silver reacts with sulfur compounds in the air or food, forming silver sulfide. This chemical reaction alters the composition of the spoon, resulting in the tarnished appearance.
