LAC 28:XI.9744. Matter and Its Interactions

A. Using data, identify changes that occur after a chemical reaction has taken place (e.g., change in color occurs, gas is created, heat or light is given off or taken in). B. Use drawings and diagrams to Identify that adding or removing thermal energy increases or decreases particle motion until a change of state occurs. C. Use a model to identify a chemical reaction in which the mass of the reactants is shown to be equal to the mass of the products. D. Use a model to show how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
