How would you justify whether reactivity is a chemical or physical property?
May 29, 2015
- Reactivity is surely a chemical property as it is determined by the valence electrons of a substance.
- Secondly, always a chemical change determines physical change in the substance. So if chemical properties of a substance is changed then surely its physical properties will have some or the other change.Example: formation of magnesium oxide after burning in air.
- But,if there's a physical change,that doesn't mean always there will be a chemical change too. Example: Cutting of wood.
I guess it will help..
