Document Summary
List some examples of each: chemical change: when atoms rearrange and the original substances transform into different substances. Ex: iron rusting, sugar burning i: often shown by temperature or color changes, physical change: results in a different form of the same substance i) Includes state of matter changes: what is the difference between a physical property and a chemical property, chemical property: a property that a substance displays only by changing its composition via a chemical change i) Ex: corrosiveness, ammability, acidity, toxicity, etc: physical property: a property that a substance displays without changing its composition i) What do we mean when we say a reactant is in excess: limiting reactant: the reactant that limits the amount of product in a chemical reaction i) The reactant that makes the least amount of product: a reactant is in excess when it does not limit the amount of product. Any c in a combustion reaction produces co2 and any h forms.
