chemical change:)
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Physical change
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
Burning is a chemical change.
Moving furniture is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, while a physical change involves a change in the physical state or appearance of a substance without altering its chemical composition. When you move furniture, you are simply changing its position or location, which is a physical change.
Both. A chemical reaction occurs & a physical change is noticeable.
Oxidation and reduction are chemical changes.
It's a chemical change because the apple is oxidizing. It turns brown, because of the oxygen, hence the word " oxidizing".
Oxidizing mercury is a chemical change because it involves a rearrangement of atoms in the mercury molecules to form new compounds (such as mercury oxide). This results in a change in the chemical composition of the substance.
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
It is a chemical because it is producing a new substance.
A physical change
Burning is always a chemical change. Look at it like this; if you can't put it back together like it was to begin with, it most likely has gone through a chemical change i.e. copper oxidizing, burning paper...
No, the fragrance of a flower is a physical change, not a chemical change. The scent is a result of volatile compounds evaporating from the flower, but the chemical composition of the flower itself remains the same.
Physical change of the paint, not the door.
it is a chemical change
An acid is a chemical compound, not a physical or chemical change.
