name 3 economic advantages of a high atom economy
makes more effecient use of raw materials
less waste to deal with
lots of raw materials go to make desired product
what is an environmental advantage of high atom economy
as less resources used and less harmful chemicals placed into the environment
what is the equation for atom economy
