Slide10Chemical Formulas/Reactions
State the Law of Conservation of Mass:
When the Law of Conservation of Mass is said to be “conserved”, the chemical equation must be _____________________. This means that the total mass of the _________________________ must equal the total mass of the products.
List the possible examples of evidence that indicate a chemical change has occurred:Temperature change Gas Produced
Light produced Color changePrecipitate formed
The amount of mass in the reactant equals the amount of mass in the products.
