Physcial or Chemical Change?

For many of us Physical and Chemical Changes were just a review of what we learned from grade 8, 9 & 10...but for some of us who don't, Physical and Chemical Changes are easier than you may actually think!
Here are some key notes from Mr. Doktor that will give you ideas and insight on what Physical and Chemical Changes are all about:

 

Physical Change:

- Involves changing shape or a state of matter
    Examples: Crushing, Tearing, etc..

- No new substances are formed
    Examples: Cutting wood, Boiling water, etc...

Chemical Change:

- New substances are formed
- Properties of the matter changes

    - Conductivity, Audicity, Colour, etc...
      Examples: Iron rusting, Burning wood,
                        Digesting food

Now that you are a bit familiar with Chemical & Physical Changes, can you identify some of the things in this video that is either chemical or physical?

We also did some review on writing and balancing chemical equations

Here are some examples, try them!

1. A solution of aluminum chloride, carbon dioxide and water can be prepared mixing pure aluminum carbonate with a solution of hydrochloric acid

2. Write a balanced equation for the reaction of aqueous barium hydroxide neutralizing a solution of phosphoric acid if solid baruim phosphate and water are produced

To finish off, here's a funny video for you to watch but NEVER try at home
