  1. SPI 0807.9.10 Reactants & Products Notes Science Tennessee SPI Objective: Identify the reactants and products of a chemical reaction. Essential Question(s) How do I recognize reactants and products in chemical equations? I Can Statement I can identify reactants and products in a chemical equation. Success Criteria I can prove that I understand this topic by showing you the reactants and products in a chemical equation.

  2. SPI 0807.9.10 Reactants & Products Notes Science Chemical Reactions • Are represented by chemical equations Chemical Equations • Have two parts: (1) reactants and (2) products • Reactants: are the "ingredients" of a chem reaction. These are the things you are combining… the things you start with. • Products: are the things that you produce in a chemical reaction… the things you end up with. 2H2 + O2 2H2O Reactants (Hydrogen & Oxygen) Product (water) Example:

  3. Examine the chemical equation below. • This example represents burning charcoal on a BBQ grill • Notice the chemical symbols, chemical formulas, and signs. Identify the reactants and products Reactants: Carbon (C) & Oxygen (O) Product: Carbon Dioxide (CO2) Here are the reactants Here are the products Yields Sign Plus Sign Burning Charcoal Reactants: Carbon & Oxygen Product: Carbon Dioxide

  4. SPI 0807.9.10 Reactants & Products Notes Science Examine the reactants Reactants- starting materials in a chemical reaction Remember: the arrow ALWAYS points away from the reactants! Here are the reactants

  5. SPI 0807.9.10 Reactants & Products Notes Science Examine the products Products-substances formed/produced in a chemical reaction Remember: the arrow ALWAYS points towards the products! Memory Trick Letter “P” for points goes with letter “P” for products. The arrow always points to the products! Here are the products

  6. SPI 0807.9.10 Reactants & Products Review Science 2H2 + O2 2H2O Identify the REACTANTS in this equation. Reminder: The arrow always points towards the product(s)! Reactants 2H2 and O2 …or you could simply identify the reactants as H (hydrogen) and O (oxygen)

  7. SPI 0807.9.10 Reactants & Products Review Science N2 + 3H2 2NH3 Identify the PRODUCT in this equation. Reminder: The arrow always points towards the product(s)! Product 2NH3 …or you could simply identify the product as NH3(ammonia)

  8. SPI 0807.9.10 Reactants & Products Review Science 2NaCl 2Na + Cl2 Identify the REACTANTS in this equation. Reminder: The arrow always points towards the products! Reactants 2Naand CL2 …or you could simply indentify the reactants as Na (sodium) and Cl (chlorine)

  9. SPI 0807.9.10 Reactants & Products Review Science Sn + 2H2O SnO2 + 2H2 Identify the PRODUCTS in this equation. Reminder: The arrow always points towards the products! Products Sn and 2H2O …or you could simply indentify the products as Sn (tin) and H2O (water)

  10. Review Questions SPI 0807.9.10 Reactants & Products Science The arrow always points towards the product(s)!

  11. Review Questions SPI 0807.9.10 Reactants & Products Science The arrow always points towards the product(s)! Reactants Products

  12. Review Questions SPI 0807.9.10 Reactants & Products Science The arrow always points towards the product(s)!

  13. Review Questions SPI 0807.9.10 Reactants & Products Science The arrow always points towards the product(s)! Reactants Product

  14. Review Questions SPI 0807.9.10 Reactants & Products Science The arrow always points towards the product(s)!
