Vehicle airbags inflate when the ionic compound sodium azide rapidly decomposes to the elements sodium and nitrogen. If the azide ion is a polyatomic ion with the formula N3−, what is the formula of sodium azide?

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
