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.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

idk what is it? is this a question that you know the answer or u dont
