Which one is a chemical change rusting of iron or melting of iron?
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Why is melting of butter is a physical change whereas rusting of almirah is a chemical change?
Melting of butter is a physical change because it involves a change in state from solid to liquid without altering the chemical composition of the butter. Rusting of an almirah is a chemical change because it involves a reaction between iron in the almirah and oxygen in the air to form a new substance, iron oxide, which has different properties than the original iron material.
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
Is iron rusting after being left outside a chemical change?
Yes. Iron rusting is a chemical change. Rust is no longer iron, but is iron oxide, therefore a chemical reaction has occurred.
Is iron rusts a physical or chemical reaction?
Iron rusting is a chemical change.

Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
Iron rusting is a chemical change since it involves the formation of new substances due to a chemical reaction between iron and oxygen. Copper melting, water freezing, and gas condensing are physical changes where the substances may change state but do not form new chemical compounds.
Why is rusting iron a chemical change what is classifications?
Because the rusting of iron is based on a chemical change, a reaction of oxydation.
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.
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
Can rusting iron nails be a chemical change?
Rusting of iron is chemical. It is the combination of oxygen with the iron, creating a different chemical: rust or iron oxide.

Is iron rusting a physical change or a chemical change?
it is a chemical change
Is iron rusting after being left outside a chemical change?
Yes. Iron rusting is a chemical change. Rust is no longer iron, but is iron oxide, therefore a chemical reaction has occurred.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
