CHEMISTRY SECTION 1 The composition, structure, properties, and reactions of a substance. Useful Chemistry Over the past 100 years there has been incredible advances in Chemistry (overall
knowledge of chemical structures and reactions, ability to produce synthetics) Many of the things we take for granted today were unimaginable when your greatgrandparents were your age. Our growing knowledge of chemistry has made many of these processes and products possible. For example
Farmers and gardeners used manure for their livestock to fertilize the crops and gardens. Now most use fertilizers produced in chemical laboratories. Synthetic PESTICIDES: Herbicides kill unwanted plants Insectides kill unwanted insects
Polymers A Type of compound(2 or more elements) that occurs in nature E.g. Silk in spider webs and sap from rubber trees Synthetic Polymers A Polymer is a giant molecule made up of
many small identical sub-molecules. Neo prene shoe soles, hoses, wet suits Polyethylene milk jugs Polystrene styrofoam ups, insulation Polyurethane upholstery, clothing Alloys mixture of metals
Many of the products you use today from cars to jewellery are made from alloys. Steel is an allow of iron and chromium. Pure gold is very soft and gets damaged very easily so most jewellery is made with alloys.
Other examples of common materials that have changed over the past 100 years 1.3 Chemical Safety At Home and at Work We use chemicals every day. List 5 chemicals you use daily/ weekly:
Examples: Bleach/ cleaning products Toothpaste/ Nail polish remover, make-up/ soap Cologne/ perfume Oil/gas in cars Pop Printer ink Chlorine in pool or hot tub
WHMIS: Which stands for Workplace Hazardous Materials Information System. MSDS: Material Safety Data Sheet HHPS: Hazardous Household Product Symbols
WHMIS E.g. WHMIS Compressed labels aregas on the container that contain the material.
The label summarizes how to handle it. People who work at jobs where chemicals and toxic cleaners are used t be educated in WHMIS training. WHMIS Oxidizing Flammable Material
WHMIS Poisonous and Poisonous Material Infectious Material (TOXIX) WHMIS
Corrosive Biological Material Hazard Reactive MSDS sheets are slightly more detailed. They are not stuck to a container. They give information on the physical and
chemical properties of the material. Safe handling, first aid advice and disposal procedures Hazardous Household Product Symbols HHPS: These types of labels are found on
products that are: reactive (likely to explode, or create a violent reaction if mixed) dangerous and toxic. They are bright and visible, so that your attention is immediately drawn to the notice, and you know to be careful with it.
HHSP Stop signs indicate danger. It is the most harmful of the HHSP They are red Diamonds means warningmedium warning They are orange
Upside down triangles mean caution the least dangerous, but still be careful They are yellow
