∙ 12y agono. a chemical change is a change in the chemical properties, i.e. it would change the chemical formula of the substance. magnetizing the needle does not change it into a new substance, it is a property which can be observed without changing the needle chemically. Magnetizing a needle is a physical change, not chemical change.

Is a Chemical change of pizza Paper and An iron nail or of Physical change?
iron nail
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.
Is letting a nail rust a physical or chemical change?
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
Is a rusty nail a chemical or physical change?
A rusting nail is the oxidation of iron, in which the iron in the nail and the oxygen in the air react to form a new substance, iron oxide, with different properties from the iron and the oxygen.
What is a physical change Milk becomes sour an iron nail rusts?
Both milk souring and iron rusting are chemical changes.
Is a Chemical change of pizza Paper and An iron nail or of Physical change?
iron nail
Is tarnishing an iron nail a physical or chemical change?
It is a chemical change
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
Is an iron nail melting a chemical change?
No.
Why is a rusted nail chemical change not physical change?
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
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.
Is rusting a nail a physical change or chemical change?
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Is bending an iron nail physical change or chemical change?
physical
Is heating an iron nail a physical or chemical change?
Heating is a physical change.
Is letting a nail rust a physical or chemical change?
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
How do you know rusting on a nail is a chemical change?
It is a chemical change because the molecular nature is changed; iron become after oxidation an iron oxide.
Why is rusting nail chemical change?
A rusting nail is the oxidation of iron, in which the iron in the nail and the oxygen in the air react to form a new substance, iron oxide, with different properties from the iron and the oxygen.
