Use the word equation below to explain how a chemical change differs from a physical change. iron + sulfur -> (heat) iron sulfide

Considering the equation :

iron + sulfur heat > iron sulfide

or

Fe + S > (heat) FeS  

So, When iron and sulfur react to form iron sulfide. The chemical composition in the reactants that is of iron and sulfur is different from the chemical composition of the products that is iron sulfide. But in a physical change, the chemical composition of the sample doesn't change. So this reaction is a example of chemical change.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
