Presentation transcript:

January 22, 2016 Learning Target: I will construct a chemical equation for a chemical reaction. Entry Task: All chemical reactions have reactants (inputs) and products (outputs). In your own words (don’t use the glossary!) define the terms reactant and product as you think they apply to yesterday’s lab. Agenda: Lesson 8.2 – Reacting two Elements Student Sheet 8.2 Reflecting Questions 1-3 pg 95 Chemical Reaction Notes Turn in lesson 8

Chemical Reactions Reactants: The starting substance(s) in a chemical reaction. The reactants in yesterday’s lab were oxygen (O2) and iron (Fe)

Chemical Reactions Products: The new substance formed as a result of a chemical reaction. The product in yesterday’s lab was iron oxide (Fe2O3)

Chemical Reactions Word Equation Reactants Product Iron + Oxygen Iron Oxide **Think of chemical equations like math problems, but with elements and/or compounds instead of numbers**

Chemical Reactions Chemical Equation Fe + O2 Fe2O3 Reactants Product(s) Fe + O2 Fe2O3 ** When writing chemical equations use an arrow in place of an equal sign**

Chemical Reactions Reaction Type Iron + Oxygen Iron Oxide Reactants Product Iron + Oxygen Iron Oxide Fe + O2 Fe2O3 Synthesis Reaction – A chemical reaction in which two or more elements react to form a new compound.
