ciaras bike has rusted, which means that the iron in the metal changed to rust. what has occurred? an energy formation an exothermic reaction a chemical reaction a precipitate formation
Answer
Brief Explanations:
Rusting is when iron reacts with oxygen and water to form iron - oxide (rust). This is a chemical change where new substances are formed, which is characteristic of a chemical reaction. While rusting is exothermic, the most general and accurate description here is a chemical reaction. Energy formation is not the main process described. Precipitate formation occurs in solutions and is not relevant to rusting of iron in air.
Answer:
C. a chemical reaction
