Is rusting a physical or chemical change give reason for your answer?
Rusting of iron is a chemical change because it happens due to a chemical reaction between iron and air in presence of moisture.
Why is rusting a chemical change for kids?
Key Chemistry Terms In chemistry, the substances you start out with are called “reactants,” and the ending substance is called the “product.” Iron, water and oxygen are the reactants involved in the creation of rust. The product is hydrated iron oxide, often referred to as rust.
Is rusting of iron is a chemical change yes or no?
Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.
Why is rusting of iron a chemical change but magnetization of iron is a physical change?
Rusting of iron is oxidation of iron from Fe to Fe2O3 and is an irreversible process. hence a chemical change. Whereas, iron bar gets magnetised only when it is in vicinity of a magnet and is a reversible process, hence it is a physical change.
Is rusting of iron an endothermic process?
Iron rusting : It is an exothermic process because heat is released during the iron rusting process. Hence, an egg cooking is an endothermic reaction. whitan8586
When iron rusts is it a physical change or a chemical change?
When iron rusts, iron molecules react with oxygen molecules to make a compound called iron oxide. Rusting would only be a physical change if iron molecules remained pure iron throughout the process.
Is rusting of iron a combustion reaction?
Rusting of iron is a combustion reaction because it involves oxidation of iron, an exothermic reaction. With rust, the iron atoms combine with the oxygen atoms in the air forming iron oxide or ‘rust’.
Is iron turning red a chemical change?
When iron is heated until it turns red, the color change shows that a chemical change has taken place. 17. When matter undergoes a chemical change, the composition of the matter .
