1). a). what is the difference between a physical property and a chemical property?

b). give an example of one physical property and one for chemical property for each pf the following: wood, gasoline, and baking soda?

Physical is the property related to the forces and physical phenomenon's and the thing that has a physical property doesn't reacts with something. Chemical property is based on the reactions between atoms/ chemical compounds , the bonds are developed between electrons so it's often refered to the chemical elements.
