yea your correct ouo Chemical change is any change that results in the formation of new chemical substances. At the molecular level, chemical change involves making or breaking of bonds between atoms. For example, these changes are chemical: iron rusting (iron oxide forms) gasoline burning (water vapor and carbon dioxide form) eggs cooking (fluid protein molecules uncoil and crosslink to form a network)

during chemical reaction, objects turn colors, and I was thinking because the screwdriver changed color while rusting, that would be a chemical change
