What is the main difference between a physical and chemical property?
a chemical property, objects must undergo a chemical reaction and change into a new substance. For example: corrosion (iron rusting)

What happens to the density when you add or take away mass?
you change the density. The more mass you have, greater the density; less mass less density.
