Is a nail rusting a physical or chemical?
A nail rusting is a chemical 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.
Is bending an iron nail physical change or chemical change?
physical
Melting a nail physical or chemical change?
Melting a nail is a physical change because only the state of matter is being altered, from solid to liquid, without changing the chemical composition of the nail. The nail can solidify again by cooling, showing that the change is reversible.
Is hammering a nail a chemical or physical change?
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
Is heating an iron nail a physical or chemical change?
Heating is a physical change.
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 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 nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
A nail rusts is a chemical or physical change?
The rusting of a nail is a chemical change because it involves a reaction between the iron in the nail and oxygen in the air to form iron oxide (rust). This results in a new substance being formed with different properties than the original nail.
Is freezing of water evaporation of gasoline and rusting a nail a physical change?
Freezing of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
Is removing nail polish chemical or physical change?
This is probably an example of the sort of ambiguity which is the reason 'physical' and 'chemical' changes tend not to be mentioned outside of early science education. The exact physical make-up of the solute (nail polish) is not changed, but chemical bonds are both broken and made in this process (various intermolecular bonds). The reaction is reversible, but then, all chemical reactions are reversible, but require extra energy put into the system to reduce the entropy. Probably the best approximation would be to say it is a physical change, since all/most of the molecules involved are structurally unchanged.
