How is the Law of Conservation of Mass demonstrated through the balancing of chemical equations? 2c. How would the equations for a chemical reaction differ from that of a nuclear reaction? 2d. What are the ways that you can differentiate between different types of chemical reactions? 3a. How do the reactants and products differ in synthesis, decomposition, and single replacement reactions? 3b. How are the products of fusion and fission different? 4. What is the relationship between the amount (mass) of products and reactants in a chemical reaction? Evidence Outcomes (District): 1. Examine, evaluate, question, and ethically use information from a variety of sources and media to investigate the conservation of mass and energy. 2. Recognize, analyze, interpret, and balance chemical equations (synthesis, decomposition, combustion, and replacement) and nuclear equations (fusion and fission.) 3. Predict reactants and products for different types of chemical and nuclear reactions. 4. Predict and calculate the amount (mass) of products produced in a chemical reaction based on the amount of reactants.
