Unit 1: Applications of Matter and Chemical Change 100 years ago you would have had things such as unprocessed cheese, Beef jerky, eggs, or materials like tent canvas, raw cotton or sheep skin and leather shoes or boots. What are some items that have just been developed in recent history?
Polymer – The word “polymer” comes from the greek words poly (many) and meros (parts). A polymer is a giant molecule made up of many small and identical sub-molecules.

HHPS – hazardous household product symbols WHMIS – workplace hazardous materials information system
What are some indicators that a chemical reaction has occurred?
Types of Chemical Reactions • Combustion fuel + oxygen carbon dioxide + water vapour + energy • Neutralization acid + base salt + water • Simple Composition Reaction – Two or more elements combine to form • a compound. Whenever you see two elements as reactants, you • know that the reaction is a simple composition reaction. • Simple Decomposition Reaction – A reaction that breaks a compound into • its component elements.
