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.

2. 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 + O H2O
Example:

3. 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
Burning Charcoal
Reactants: Carbon & Oxygen
Product: Carbon Dioxide

4. Reactants Product Examine the reactants Examine the product
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)!
