Notes SPI 0807.9.10 Reactants & Products Science Learning Intention: Identify reactants and products in a chemical reaction. Purpose: to recognize the components of a chemical reaction. Success Criteria I will show that I understand this topic by earning a 90 or higher on the quiz. I Can Statement By the end of this unit I will be able to say... ...I can identify reactants and products in a chemical equation.

2H2 + O2 2H2O Example: 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. Reactants (Hydrogen & Oxygen) Product (water) 2H2 + O2 2H2O Example:

Identify the reactants and products 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) Below are the reactants Below are the products Plus Sign Yields Sign Burning Charcoal Reactants: Carbon & Oxygen Product: Carbon Dioxide

Memory Trick Reactants Product Examine the reactants Reactants- starting materials in a chemical reaction. Examine the product Products- substances formed/produced in a chemical reaction Remember: the arrow ALWAYS points towards the product(s)! Memory Trick Letter “P” for points goes with letter “P” for products. The arrow always points to the products! Reactants Product

Identify the REACTANTS in this equation. 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)

Identify the PRODUCT in this equation. 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)

Identify the REACTANTS in this equation. 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 2Na and CL2 …or you could simply indentify the reactants as Na (sodium) and Cl (chlorine)

Identify the PRODUCTS in this equation. 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)
