Chemical properties
Reactivity
Through chemical reaction (chemical reaction changes the substance)
You think probable to catalysts.
These substances are called reactants.
A physical property can be observed without changing what the substance is made of. A chemical property can only be observed by altering a substance through a chemical change.
Usually it means that something has gone through a physical change and any chemical properties of that substance are not altered.
Burning wood is a chemical change because the chemical makeup changes through the addition of heat. wood + heat = ash and other gases Pretty much when one substance changes into another substance and the change is irreversible, it is a chemical change.
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.
